 Sir you reached home, not yet dear, hopefully you know, know, know Tanya, very good, so you have finally reached to Bangalore. 20 no, 25 questions I created, what I remember is, how come you are getting 20 questions? Yeah, I got like, have I forgot to say 5? 21 slides. How many? 25, not 25 is fine, 25 is fine. Good, good, good, good, good, good, good, good, good, good, good, good. Sir where? In Bhopal only, dear. Sir, you will get 2 weeks quarantine, sir. If I will come to Bangalore, yes, home quarantine. Yes, home quarantine. Anyone who has little trouble? Sir, my free start today. Sir, you have reached? Good, good, good. Okay, good, good, so you have 2 weeks start today, so hopefully, like how was the procedure, just for the awareness sake of it? Sir, it was like, I mean it was a little kind of slow, but they were very disciplined on the airport, so. Okay, so no wastage of time, no waiting in the sun and all that thing, right? No, no, no sir. Okay, good, good, good, good, good, good, good. So 55 people already here, very good, very good, very good, very good, very good. Quick, I repeat the code, 779338 is the code. So either we reach to 05 or 60, whichever first we will hit it. No addition. 779, okay, 4, quick, 1, 2 and here we go to the first question. Sir, your screen share has stopped. Okay, thank you very much for the update, I'll do that. Meanwhile, you guys are doing this. 779338 is the code, very good, very good, very good, very good. 779338, very good, very good, very good, very good. 51 people responded to this and boom. Why? How come? How come, how come, how come, how come this happened? An object that is slowing in the positive direction would be experiencing a deceleration. True. Psych theme is positively psych or negatively psyched here. Aditya. Thank you very much, thank you very much. No problem, no problem, relax. Can we move on to the next question and before that, I'll look at the leaderboard. 35 plus 16 people responded and let's see. Okay, not a huge difference between Tarun, Abhishek and Tarun was the fastest one to respond. Abhishek is good. Okay, let's go to the next one. Good, good, good, good, good, good, good, good. Same number of responses. That's beautiful. 52 people responded, 53 people responded now. That's beautiful. That's beautiful. That's beautiful. And again, the same scenario. Guys, total calculation will be required. Total. An object originally addressed. It will be suppose, suppose, suppose, suppose, suppose, suppose, suppose, suppose, relax. Suppose if you want me to calculate also, I will do that. Okay. Clear. It's equal to ut plus half. Suppose you even take it 10. T square is 100. It is 500. So if this would have been 491, thinkable. True. But it is not 491. Right. Okay. C4 clear, C4 clear, C4 clear, C4 clear, C4 clear. Good, good, good, good, good. Good. Let's go to the next question. And before that, look at the shuffled leaderboard, I guess. So not that much shuffled at the top ranks. Just midway is there. Oh, truck. Okay. Tarun was the faster one to respond to this as well. Very good. Very good. Very good. Very good. Let's look at the next question. Good. The tsunami of responses is lit. 5 seconds, 35 responses was like boom. Like that's why my eyes couldn't notice it. If this would have been 5 seconds, 30 responses, my eyes could have noticed it. Right or not? Do you know this thingy or not? Your eyes can record one by sixth part of a second. Yes or no? Good. 15 people. There's a confusion. So question number one. No, no, no. Surely not. You know me. One by ten can be processed by brain, but eyes, what I have heard about is one by six. Am I correct? Sir, Arushi here. I had joined before and couldn't hear when I left and came back. My points are gone. No problem. Let's see which one question is there. We'll see what happens. Okay. Thank you very much for the update. And here we go to the third question. It's pretty obvious when we're done. Very intuitive. If an object speed is constant, speed is constant, then acceleration is zero. Yes. Right. No doubt. Good. Next question. So Arushi, do you have your scores here? Like your scores got updated. Why aren't... Can you just unmute and report? No, sir. No, you lost it? Yeah. Sorry. Sorry. Your video is kind of laggy. Yes, so it's laggy. My video is kind of... Okay. Let's have the lag test. One, two, three, four. Ten, me, fifty-five. Fifty-five. Kind of good. Kind of good. Kind of good. Don't say your video. Your audio is clear. Okay. Okay. I understood it. Whatever I'm writing on screen, please respond to it. Send that the same thing in the chat. Sir, I had a doubt though in this question. Sir, if an object speed is constant and it's going in a circular path, the speed may be constant, but isn't the direction changing? Got it, but we are not talking about circular motion now. We are still in one-dimensional motion, right? Okay. Yes, sir. Okay. Good. Very absolute query. Okay. Good. Good. Good. Good. Good. Good. Good. Good. Good. Good. Good. Good. Good. Good. ALL!! Good. Good. Good. Good. Good. Very good. And that was a beautiful scenario for the next question. Good. Good. Good. Good. Good. Very good. Good. Good. Good. Good. Good. Very good. I don't think so. E-R... Explanation. Required. E-R... Explanation. relax straight line and slant line okay a line it can be straight or slant will indicate a uniform acceleration okay. If it is a flat line parallel to the time axis then it will indicate zero acceleration but if it is slant it will indicate some positive or negative acceleration but uniform yeah so good good good good good good good go all those booms and bombs let's see okay very good very good very good very good let's go here and the shuffle scenario shuffle shuffle truck Rishabh I got I got him missed it Vihan Rishash Srijan Vihan Nitya Anish are leading the show now very good very good very good very good very good and let's look at the next question average speed average speed and average velocity can be equal true or false good good good to see a good bunch of responses coming towards a late it's okay you guys are reading it learning it fine yes why ten people said no but there is a word uses can they can be equal if it is in same and direction it's a linear approach can is a very important word over there can is a very very important word okay show let's look at the next question and before that the shuffle leaderboard I guess not that much shuffled Rishash Srijan Nitya Vihan Anish they will have an internal shuffle no no shuffle beautiful beautiful beautiful beautiful beautiful let's go for the next question motion is the change of position during an interval of time true or false true or false good good good good good good good good good good good good at tsunami of responses 10 second 50 people have already responded that's beautiful so when will the hard questions come when we have to calculate we want the hard questions because like otherwise everybody keeps getting the right answer and it's only speed okay good suggestion that will be remembered 38 people and 17 people are responding to it but it's still not the easiest question for everyone okay anyway good good good suggestion very good very good very good very good very good very good very good so motion is the change of position during an interval yes no doubt undoubtedly the very first line right good good good good good good good good next question and before that I guess now we'll have the Rishabh missed it with a how all this happened but Srijan Ghosh Vihan Nitya Karun drove fastest to respond was Karun very good very good and here we go to the next question good good good good good good good good good nice speed of responses 55 56 57 people have responded by now very good very good very good very good and then there was a short as a variation I have made let's see whether people notice that or not false is the right answer true is wrong beta because it should be half 80 square not half ta square again a boom COD post reaching to Bangalore here things are not good okay good good good good let's look at the leaderboard mute yourself why am I not able to mute please mute yourself whoever is unmute omit naffil can you please mute yourself the cursor not work thanks a lot I'm so I found one mute so that's a myth naffil omit naffil please mute okay left audio that's good enough no no no no my system got system got suck okay okay okay I am I am coming back coming back please wait so both of your accounts are on both of your logins are on unmute so if you can mute one of them it won't repeat guys chill it the reason it's echoing is because both of source logins are not good evening everybody this is Tushar I hope you are doing okay so probably there is some glitch at uncle search and no worries you'll be back in some time meanwhile let me check your physics physics knowledge lots of people were asking about easy question so tell me one more one you know all of you have to answer this now let's say earth is revolving right earth is rotating at its own axis all of you know that okay so if I jump at my place okay and somehow I get stuck there can I reach America if I jump high enough and why because I am jumping the earth is rotating so after 12 hours I should land in America isn't it who can explain why does it not happen so airplane goes up is stationary over there and what's inertia what's inertia why is inertia motion will continue to be at motion and if you jump so then you will you have been moving before you jump as well so even when you jump you have been moving along with the earth without realizing it yes so good good that you answered that well okay now second question if you don't start the engines in time the plane will lose speed and start stalling and I am on the let's say I'm in Stratosphere I'm I'm I'm just static over there okay so through says I can go to linger okay okay tick I will take taste that now second question you are on a train and you are having a object in your hand yes what for me sure this is not open please wait for presenter to activate it yes it's not activated right now because uncle sir is rebooting his system so meanwhile I'm engaging with you guys so tell me if you have an object in your hand and you're moving on a train and you throw it vertically upwards will it land in your hand or it will land with you know behind you or behind on the in your hand or behind so there are mixed how many of say how many if you say so in your hand in your hand not behind say in your hand as long as you are in the train and the object has been thrown in the train okay so uh yes so most of you are correct it will land in my own hand because the when I released it it was moved with the same velocity horizontal velocity with which I was moving so in the horizontal direction it will land in my own and very good okay that's nice now tell me another question so uncle sir is back are you back uncle sir hello yes yeah rebooted yeah done working fine now yeah yeah great so you can continue so guys um physics uh so those who were expecting hard questions for me the only thing is yes the right answer is you will have you will if you're asking me then we it will land in your hand okay so hence um there will be combination of easy and hard questions every time so hence uh you know try to maximize your accuracy so if it's easy I would expect after the session is over that you have 100 accuracy right so hence every exam is like that there are there will be surprises it might be easy and when it is easy it is more tough actually to beat the competition so that's where you need to be more alert okay so when it is easy it is more tough to beat the competition so hence be prepared for such situations okay so we'll resume the session we'll carry on the screen visible quickly drop in a wire and yes yes visible all the best folks 100 accuracy let me see so this was the scenario for the last 35 and 16 right the question was ut is equals to half at square and now we'll be moving toward the leaderboard shuffle leaderboard so the fastest one to respond to this was as I this is the first question I guess okay this is the second question okay relax this is the third question okay this is the four like relax okay done done done got it it will come back and resume back to the same scenario double seven nine three three eight is the same code be ready on screech beta because we kind of have missed which question we were doing so any next slide can be the question for you I remember Russia not doing this okay then there was a shuffle okay okay okay okay okay I guess one more question will be yeah this is the last question ready I guess now we'll have a fresh question on screen yes it is please look at it a similar question again the importance to a word so please please please please please again the same tsunami of 58 people responding to it so I guess 58 people are here but it's not indicating that everyone has responded who who with the motivation given by the char sir sir the efficiency and the accuracy has increased to a good level 49 people answering it correct nine people are still like somewhere missing the taste of it no problem no problem no problem again the word can is important okay good good good good good let's look at the leaderboard sorry for the disturbance we had in between because of the system getting hanged and who's the first one to respond who is the fastest one to respond I guess region because 982 turn on very good very good very good very good very let's look at the next question again be attentive if you are giving importance to the previous two similar question okay then you will get it easily telling you midway that's important word is missing so yes there will be a variation in the answer let's see if the accuracy has increased or decreased for us a variation is there because better the word can was missing if you go here the word can it can be called it's not mandatory equal okay very good very good very good very good very good nishant very good everyone let's look at the leaderboard I'm giving hint that's bad habit for me I generally give hint okay but after a good duration of time when people have already made the mistake so I give you enough chance to make mistake I'm very much pro toward making mistakes Shriram is the fastest one to respond the upper leaderboard is getting shuffled continuously and look at to the next question good please read it get it accurate like it it should be a record kiyaar bhai out of 60 people 60 made it correct good good good good good good good good good good guys excellent excellent excellent excellent again a nicer accuracy very good very good very good very good very good I don't think so there is an explanation required yes the initial point is called origin it doesn't mandate arises to be 0 comma 0 though right or not it can be anything with respect to the other point with respect to just a simple question over the quick chat just a simple question over the quick chat with respect to minus 1 comma 0 what is the position of origin with respect to minus 1 comma 0 what is the position of origin with respect to minus 1 comma 0 what is the position of origin 1 comma 0 one step toward the x-axis and 0 steps on the y-axis 1 comma 0 bacha with respect to minus 1 comma 0 the position of origin is 1 comma 0 very good very good very good very good very good very very good very good very good again so making the same line how many of you are at rest at this momentum and please answer this question only if you are damn sure absolutely you can say with whatever probability we are at rest if you can say that either the way you can say I am not at rest or you can say I am at rest can you say it by absolute accuracy like absolute surety good good good good good good good good good good one person said depends on perspective I want to know the name absolutely correct very good keep it up good answer very good very good very good very good so now now now now now true false are over now you are going to have mcq's okay 10 questions true false giving you a good ticket to leaderboard let's look at the leaderboard false true false and let's examine that when all the questions are done okay we'll observe the variation shrijan Ghosh Nitya Karun Dhruv good good good Tarun is consecutively the fastest one to respond Tarun is good good good good let's look at the next question now it's going to be mtq type please like a b c and b boom there came a big boom of 20 people boom so let's see if this is active that if everyone will be responding should it close by itself or not 54 people have responses there there are still people who haven't responded yet good good good so everyone hasn't responded yet there are people who okay 56 people now responded very good 5 to 5 44 people answering it right absolutely to I did like sorry which of the following is a scalar quantity okay speed is a scalar displacement force and velocities are vector by the end of this chapter you have already been through displacement velocity and speed force is coming up in the next chapter okay good good good good good good good you have seen that video with you right so there's a lot so so we are not able to hear you again there is some problem it seems today internet is not behaving well so what are tensors people are talking about tensors what is tensor so is it the way the poses are positioned like to create effects like worlds so physics cannot physics doesn't understand the language of video games video games understand the language of tense you know physics so you have to tell in the language of physics right as a bright object that describes relations between sets of algebraic object related to vector space okay coffee please get from okay so uncle sir you're back he's he's having some trouble okay is my voice audible now is my voice audible now is my yes yes thank you very much I don't know why this is happening after so long when I am tending to move to Bangalore the scenarios are pushing me toward Bangalore actually right okay so we were here which of the following quantity is a vector scalar so the answer is feel very good very good very good let's look at the leaderboard uncle sir one question sir please yes so what is vector in biology this is the question to me no no to the people what is the vector there are magnitude and direction no in biology that is physics yeah carriers of diseases okay good so yeah so name name few vectors malaria is caused malaria is a vector-borne disease right you have heard of right which kind of which kind of mosquito it is what what me no that's not for not start from malaria you know why malaria is called malaria now you know malaria was actually a misnomer so when Napoleon was fighting the British in North America he sent his troops to North America where they got sick and returned back and Mal means bad area we is related to air air so bad air you thought that it is bad air marshy air in the northern American you know forest which is creating the sickness and they called it malaria right but then later on they discovered that it is and rest you know already okay it's trivia time over thank you thank you very much thanks a lot this is like me I don't know about these intelligent people at least for me it was a good like icebreaker with a conversation with anyone so yes the next question quickly slope offered position time graph slope slope and area are the two parameters which we look at while calculating about any graph and all now the speed of responses have decreased so I guess people are getting somewhat what they were looking for not a tsunami of responses coming all together good good good good good the slope of a position a time a graph the slope of a pt graph slope can be calculated by the calculation of tan theta or y by x okay good and 57 people responding to it times up and ooh confusion da confusion slope it is about a position time graph but yeah how can it give displacement which is itself a position how can it give distance which is itself a position velocity and acceleration were possible responses direct relation is with velocity displacement is in double folder related with acceleration s is equals to ut plus half a t square good what's code I got disconnected is double seven nine three three eight thank you Nishant thank you Aditya for helping your friends out good good good good good let's look at the leaderboard velocity being the answer for what you calculate from the slope of a position time graph or a displacement time if this would have been the name as distance time then the answer which is not there in the options would have been speed which is the magnitude of the velocity Pratham responded to this the very first Pratham oh roasted napple nine okay fine so Pratham is still following so cut off huh Pratham is signed if you can relate to this very bad joke of mine read it the reading will take a lot of time read it the reading will take a lot of time very good very good very good very good very good it is talking about average velocity as the time will tend toward half and then I'll give a hint average velocity by its very formula is total displacement covered upon a total time taken the word total is having a lot of risk like importance over there it's crucial in the definition of average good good good please mute someone had unmuted their microphone please mute you will get to know who like from yourself that whether you are mute or unmuted thirty eight people responding it correct nine five and five people but you please read it computed by change in position divided by change in time okay computer by change in time divided by change in position very reciprocal the horizontal displacement on the graph will not be giving you average velocity because velocity will need displacement upon time neither the vertical displacement on the graph yeah so let's move on to both again so today is at what rate we are moving are going around the sun what is the speed of earth around the sun anyone we are going 30 kilometers per second so last second you are 30 kilometers behind okay so every second you are you are traveling 30 kilometers that is for free okay and it translate to one lakh seven thousand kilometers per hour so in every hour you are covering one lakh seven thousand kilometers multiple New Delhi to New York you know what do you say flights so one lakh seven thousand kilometers per hour so fast and that too free amazing isn't isn't 30 kilometers per second faster than the escape velocity so escape velocity on earth dude okay thank you very much thank you very much and here turn consistently answering fastest very good turn very good very good shrijan karun Dhruv and Vihan as of now leading the show let's move forward to the next question read it invest your time think about the question you will get it right which of the following is not a vector quantity in the language of cricket it's called Dushra if someone is into cricket then they will know that there exists a technique of bowling called as leg break it's one of the comments of spinners opt for okay in that it goes for Dushra yes there also physics card formulations are deployed so Bernoulli's principle is and what is that I forgot the term Magnus effect of Magnus effect here Magnus effect so they might know some yeah most of them would be knowing those crazy people play football so Bernoulli's equation is used the same same funda which is used to fly airplanes is used in cricket as well for both for swinging the ball okay and given see in order to give it a pace you swing it in order to give it a good spin you flight it 51 people answering right for the flight Magnus effect is uplifting in planes okay good good good good good good the question but I straight what was scalar initially is not a vector now same thing good good good good just checking who all are awake you know I was going to put the last question as how many days are there in this month then I thought no that would be really bad I literally love putting the last question I was thinking that let's put me how many days are there in this month and first I'm responding to the question past is good good good good though the top three rankers are kind of same and we are going to the next question tsunami of answers good good good good good good good good before people have responded the instantaneous velocity and instantaneous speed so I'll vote here most of the votes will be falling into the line of C or D charlie or delta but there exists a shorter variation because pedometer has some constraints because of which it will go only with one of the two options instantaneous speed or instantaneous velocity good good good last five seconds three two and one charlie no one opted even for delta few people opted for alpha okay just uh better average speed average cannot be it is about total distance covered upon total time at the very instant what is the definition of instantaneous speed or instantaneous velocity like by lottery system I'll calculate cost of cost of can you unmute and tell us the definition of instantaneous speed or velocity yes sir so instantaneous speed or velocity is the speed at that moment only very good so for that you need the speedometer when you look at this pedometer at the very instant it is telling you that speed very good very good very good why not velocity because velocity will need a sense of direction which lags in I don't know which is lacking in speedometer speedometer doesn't tell you the direction very good very good very good what is the difference between speedometer and odometer so odometer shows the distance but speedometer shows the speed so in your motor vehicle are two inbuilt parallely or like so in in in the vehicle there is one more meter what is that for beyond the speedometer there is something else what is that same rpm rpm meter rpm of rpm of the speed of the wheels no revolutions per minute yes but what who revolutions per minute of what something 10,000 in the oh that meter what does it measure it's also speed for angular speed which is measured in rpm and that's like the revolutions per meter of the engine's output engine's axle spinning right at that speed so when idling it is around 1000 by any chance has anyone visited the workshop with your parents why am I asking it is because have you ever seen the car or vehicle from down not upside down service the bottom view yeah which workshop which were service stations get a chance visit good good good good so 42 people responding it correct no one selecting the another choice by me very good very good very good and only 10 minutes left can we like go quickly without it very easily that will be done this will be over by nine okay it will remain a centum r will not become centum 1.2 hours so tarun and why you bully me our dear friend that's me so that's me such a painful name okay so look at the next question read it respond i hope you guys can see it i'm not able to witness it on my screen now it is witnessable over my screen as well which of the following choices does not give you a displacement velocity or acceleration neither displacement nor velocity nor acceleration good good good good this will need four hours a careful time to read this is an altered question so yes we'll surely look for some time very good very good very good very good 53 people are responded by the time now nine people to go 20 seconds placement time and acceleration time good good good good good good good good times up it will take some time for the limited speed to take up the correct responses 34 people only these but an area under position time graph will not give you anything slope of pt will give you velocity slope of vt will give you acceleration back area of at will give you velocity area of vt will give you displacement area of pt will not give you anything and slope of at as of now though is not giving you anything okay yep leaderboard so shrijan karan are maintaining their top positions both the beautiful uh shrijan was the fastest one to respond to this very good very good very good let's move through the next question read it carefully don't make a mistake please read it carefully if you'll just thought about miss you might get it wrong high probability okay what is feed feed feed fth feed number two we use a foot scale yeah that's a reconsider it f multiplied by time square something no problem no problem ask five seconds again 57 people have already responded to it why isn't it showing that everyone has so we have 58 59 people i guess 33 people only getting it right but charge it is length per meter per second square it's a length meter per second square okay now there is no meter per second square but there is some other unit of distance because it is said what which is a possible unit so you don't mentally really have to look for the you don't mentally really have to look for the si unit okay possible units if you know you know by now cgs system of unit mks system of unit there exists one more called as fpms system of unit fps yes or no why or and why or and why or and by the way what is the value of acceleration due to gravity in feet per second square what is the value of acceleration due to gravity in feet per second square 32 karun very good at least you responded remember that 32 feet per second square in feet per second square good good good good good so we are moving to the leaderboard now okay accelerating our flow so that we can finish it at nine okay so yes here we have the leaderboard uh shijan karun vihan drop having a healthy good positive con teacher shijan responding to this fastest as well very good very good very good let's look at the next question again read it relax and respond because the options are so lengthy you will have to read them good good good good odd half the time and most of you have responded to you odd responses another 10 remaining good good good let's see that everyone has responded and the time getting concluded by itself the area beneath the velocity time graph is the important term because the options do discuss about two things distance displacement speed and acceleration there are vectors and scalars as well hence importance has to be given and here we go 30 people only responding it correct no problem bachas please please please read it my system is getting stuck i don't want this to happen please please please please please namrata is like x okay namrata look here bachay the area under velocity time graph will give you displacement the area under velocity time graph will give you displacement if you remember we even proved the second equation of motion s is equals to ut plus half at square by the usage of a velocity time graph and calculating its area proceeding to the next one and before that leaderboard if at all you find keemira like the screen which i'm sharing over moxtra is lagging i'll request to ignore it for a while because the screen at menti will be time sink so it won't be influencing your performance over the quiz okay nishant was the fastest one to respond and i am going to the next question the equations of motion apply only if the three equations of motion which you have studies they will be applied only if so if you look at that you have variables u v a s t there are u v initial and final velocity that means velocity is changing s displacement okay t time time is the only beautiful constant variable yes or no the only existing constant variable clear time and then comes acceleration okay fine and when you are solving it acceleration remains as a it is and hence telling you the answer in the very last second and here we go toward the leaderboard 33 people made it wrong oh i was thinking i'll not have to put any efforts to explain this guys that's beautiful but a big shock for me at the last better it has to be a uniform acceleration then only these three equations i told you we are talking about two classification uniform motion and non-uniform motion under non-uniform motion there are two categories non-uniform motion with uniform acceleration non-uniform motion with non-uniform acceleration for non-uniform acceleration we have different scenarios for uniform acceleration we have three equations of motion which we utilize and correct many numericals now this makes me clear there is a revision required at least of the concept might not be of numericals and here we go to the 20th question again think about the equations of motion read the options and apply a little logic as well okay beyond the equations of motion there is a logic also required because the word ideally is also used good good good good good good good good last eight seconds seven six five four three two one zero 33 people made it wrong oh wow guys you are bringing me to sadness no problem relax first of all let's discuss about but they are talking about the distance okay s can be calculated by two equations yes or no the mention of s is in two equations s is equals to ut plus half at square and v square is equals to u square plus 2 ks clear from this equation it is dependent on time from this equation it is dependent on square of the velocity please okay relax that's why think about this the think about the scenario right good no problem no problem no problem no problem let's look at the leaderboard yes beta please please please please repeat the line because it was written ideally the reaction time of the driver must not matter but the reaction time should matter so but if you're measuring the stopping time even if you take two cars and then compare them side by side and then like one person starts a little late the distance from the break time will be the same got it got it got your scenario let's let's crack it by selection by rejection now okay if you have to approach that way let's crack it by selection by rejection okay so now fine let's remove the time part clear okay let's look at the other options you're saying the speed of the car surely not the speed of the car it is dependent on the square right s is proportional to square of the velocity by the third equation of question and we have done these kind of questions counted be someone stopping at a signal counted be jew cycling on the road and watching watching the kid crossing the road counted be a bullet entering into a wood stock yeah good next question before that a leaderboard and then now next five questions are very fast okay easy look at them that's why i haven't even created their ppt okay so pratham was the fastest one to respond look at the next question quickly there's a quick glance at the concepts required before the next centymar so what is the magnitude of direction south is one because the directions are always denoted by unit vector it's not zero if it is zero you will never be able to move if you have if you have witnessed the classes one for the revision sake i have sent you the video as well if you will watch it you will find the answer no problem no problem no problem relax but our directions are always denoted by unit vectors we have discussed this okay no problem no problem no problem let's go to the next question i didn't get the question it is asking that surely direction south is a vector right yeah so what is its magnitude okay very very good no problem pratham is again the fastest one to respond very good very good very good and there we go to the next question again read it i'm very good and now a tsunami of responses the magnitude of a null vector is three two zero or one helping out someone no problem no problem some way you guys are learning please put your microphone over mute someone has muted it 49 people responding it correct null vector means the magnitude is zero very good very good very good next question and is there someone who came up with the fastest response pratham again is the one responding to this fastest very good pratham very good next question this will take a little bit to read and calculate please do that if you move from one two three as your coordinate to three three one and the next quadrant it will be provided the time assumed by you in three seconds one two three and three one good good good good good good good good good no problem 54 people responded to it and let's see the response so you guys have bluntly responded as that or let me see the calculation i'll just do the calculation here you are moving from one two three two three three one the change in position is final minus initial two three minus two one one minus three minus two the displacement as a magnitude will be square root of square square square which is four plus four plus one square root nine is three displacement upon time is one meter per second okay gi got it b for doubt gi got it very good very good very good very good very good very good very good leaderboard and next question so there are people making mistakes in minor detailing okay no problem no problem no problem we'll cover it up cover it up cover it up some other day someone talked made me a like made a habit of me talking in dot com today someone made it a habit for me to talk in triplets she is leaving the show now and here we go to the question the vt graph of any uniform motion is denoted by line parallel to velocity axis line perpendicular to time axis line parallel to time axis and line inclined with t axis inclined at time parallel to time axis perpendicular to time axis and parallel to velocity axis oh none of the options are correct i guess i did not mark it in such a bizarre scenario from me uh let me see if i can correct it what was the correct answer answer was line parallel to time axis okay let me see if i can correct it option c option c should be correct line parallel to time axis and if i oh i guess we will be able to move ahead i guess i guess i guess your scores will be calculated yes okay so we are we are neutral we are neutral we are neutral okay sure so let's and this being the last question thank you very much for your time sorry for the extension because of the system problem uh and here we have the oh shijan did not get it karun vihan pratham monisha but shijan prior lead was that good that he is kind of winning the show and here we go to the last question good good good good good good good good the area under displacement time graph will deliver the area under displacement time graph will deliver and 27 people responded to it like nothing i guess when i was marking these there was some problem with the internet which the responses did not record it so what's the connection nothing is the answer because a bit of nothing area in a displacement time graph will give you nothing okay and yes we have it without influencing the leaderboard so the final leaderboard is i guess now shijan will be influenced and now i guess because there was a difference karun no shijan is the winner very good very good very good very good very good very good sorry for the disturbances in the last two question and the hanging of the system and all may god bless me so that i can easily reach to banglore and things like this can get sorted thank you very much for your patience listening to me shijan congratulations for winning this again thank you thank you very much thank you thank you very much thank you thank you sir bye bye bye bye bye thank you dear bye good night
