 get and on the count of three two one here you go guys first question on your screen where would you find a pollen ratchet mechanism very common let's see if you know what a pollen ratchet mechanism is all the questions will have only 20 seconds so mark your answers quickly three two one right what is answer bicycle so the pollen ratchet mechanism is in bicycle you know the when you you know yes so when you reverse the pedal right there is a sound which comes continuous sound which comes when you reverse it so hence the cycle doesn't go in the reverse direction only in the forward direction goes this is because of pollen racket pollen ratchet sorry pollen ratchet mechanism right very very important in so it basically if you you know do some Google search you'll get it okay so bicycles in the rear wheel pollen ratchet mechanism is there which helps the bicycle to move only in one direction if you reverse by mistake someone takes a reverse of you know start peddling in the reverse direction it will not let it let him or her do it okay so the first is here here is the first leaderboard very quick oh no Karun in ps yes one very good so first leaderboard let's see if it is maintained next question on your board so the question is what is this so most of you would have seen this while you're you know light bulb no it's a spark plug so most of you have got it right right so spark plug you will study this in 10th grade electrostatics so yes in automobiles and various other equipment it is used okay back about it yes please go ahead so like if you see at the spark plug right at like if you have that picture again like does this right at the bottom there's like in between the spark area you have extremely valuable metals like palladium and gold and silver and stuff like that not gold but you can have like silver platinum and all those matters the next next question I will illustrate the functioning of what exactly it does and how is related to your academics as well okay so here's the next question and before that leaderboard so there is some yeah we shake this time got it correct very good so here is the next question they are used in so you see this gap this gap here right between the two metal pieces this gap actually helps in producing a huge amount of spark just in time I knew it and hence you got trapped right so it is not in not used in diesel engines or steam engines it is used only in petrol engines right no it's not in diesel engines are only found in petrol engines okay now concept clear so you know in in in petrol engine you have compression I don't know if you have gone through the the functioning of an engine so what happens in in engine is the fuel and air mixture is compressed the temperature rises up and there's a spark which you know the flue gases but in diesel engines the compression is double that of a petrol engine so hence the temperature is good enough to create a spark you don't require or you ignite the fuel you don't require a spark so only petrol engines always remember so if you have a you know diesel vehicle at home okay so hence there was a trap and steam engines come on you have to feed a lot of coal and you know the spark is not needed because there the thing which pushes the piston is steam you can't really burn the steam okay next leaderboard so most of you have got it wrong okay so Aditya Supreme best is now one first position okay okay next question guys what is this very commonly common sight very common sight correct you see it daily almost near your household keep blasting okay does it yeah this is one thing which really you know good so most of you know it that is an electrical transformer what does a transformer do it steps up or steps down the voltage okay now the picture which you saw was a step up or step down no not DC only AC so the it was a step down a step up it was a step down transformer right so it reduces the voltage because at your house in your household you require only how can you figure whether step up or step down no in your in your locality near this is the equipment which you see near your household right you have seen this now what happens is the power at very high voltage comes from the you know substrate the generating station so gradually it is decreased to 220 volt it is you know when it starts from that the sub you know generators generation point generation station side it is as high as 200 kilowatt okay so very very high voltage and now in your household you use only 240 volts around that okay so next is this leaderboard first so this was a very common easy easy oh see you can see everyone has got it correct okay very good only one shuffle next this will be a fact you must know this so I can see what is the you know K means kilo thousand so I think you know this right so I have said input side so input side voltage is 11 KV 11 KV is reduced to 440 volt and then from 440 to 2 volt 240 is your face to neutral voltage you'll come to know about all of this when you study electricity but you must know that the line if you by mistake anyone touches the other day there's a transformer near my home and one cat got stuck in the input side okay and we had to call the best com people switch it off and rescue the cat okay if you if by mistake you have touched that live wire 11 KV and then you may know you would have witnessed direct evaporation from solid solid to gas no liquid okay so next this is a leaderboard good so not everyone was aware of this now you are aware please be please remember next output is 440 volt line to line voltage 440 you all use this but do you know which technology is used to manufacture these this is the same technology with which the fuel tanks are made of bikes it's called blow-molding very good most of you know know this so blow molding is used to even you must know for example all these fuel tanks have you seen the bikes on the bike just next to the rider there's a fuel tank that fuel tank is also made using this technology okay so you have something and you blow the air inside it and it becomes a chip okay turn next very good Aditya Supreme best NPSYPR next you must know this how high you are right now from mean C level easy where do you see this information where is it written where is it written as mean C level usually written yeah it's 915 915 20 again no problem right so it is 915 meters where do you see this written so when you know any airplanes no any railway station you will see whenever you enter any real platform in the railway station wherever the station name is mentioned they will also mention the mean C level height okay so majestic if you go sometime you will see that written over there okay general awareness yes you must be observing guys this is the learning next question before that eat a board okay so not everyone knew this okay so don't chat in lag if this thing I don't chat only now so hence just focus on the next question here is the next question you must have seen gsm where is gsm written see not everyone knows what is gsm by the way it is a measurement of what is gsm anyone knows what is gsm yes yes yes yes so grams per square meter is required why for printing every printer has a particular gsm requirement okay so it's you know if you feed higher gsm paper into normal printing papers gsm 40 70 so a4 sheet you go it's the paper which you use it's around 100 gsm at max normally and you can go yes so depends on you know gsm is also used in plastic sheets so wherever there is a laminate it is measured in gsm grams per square meter any laminate structure is there you get gsm there okay next eat a board not everybody knew it gsm is also a mobile technology right communication technology if you are aware of that next in terms of purity 22 karat gold is equivalent to next time you visit any jewelry shop you will see they will give you a certificate of purity there one number is mentioned right good so 91.6 the number 916 is written in most of the gold jewelry if you have if you're right now if you're right now wearing it you can check any of your you know lockets or bracelets or whatever it will be written 916 right earrings yes it will be mentioned check someone would be wearing at home or if you have any okay show next awareness so shuffling is happening that means not everyone knows all the questions that's good okay next question on your screen guys I hope you've heard of this word petric or very very intoxicating the first smell of the rain okay so so the moment I said intoxicating everyone mark nicotine right so Geo spin is produced yeah it's produced by a bacteria so whenever water falls on you know very slow moving rain so it will always be when light rain is there when heavy rains are there you will not get the smell so light rain falls on ground the bacteria which is there produces geosmin and you know this is right so geosmin is the compound for that smell and it's really really great smell okay next core petri means stone and core is fluid or blood flowing in Greek God Greek God Greek God okay so Monisha is on first position very good chalo fastest was he man shoe next question first know this if you're aware you must be know knowing this there is so it'll be written on the back in red color yes and where which law says all this so there is a rule in India it's called drugs and cosmetic rules 1945 okay which has all these categorization so should you let's drugs are without prescription in fact without prescription you should not take any medicine but should you etch drugs are little you know what is it if not taken with a proper prescription it can be hazardous so should you etch right what did I say the rules are written where is it in where is that should you etch should you etch is mentioned in something called drugs and cosmetic rules 1945 okay remember that there are lots of other other should use as well for example there is a should you see you ready and all that so it talks about in fact there is a discussion on different types of poisons also okay so everything is mentioned over there so this is where it comes from okay guys you should be very careful while chatting anything or writing anything in the common chat box okay PM 2.5 and PM 10 are food colors narcotics refrigerants pollutants what is PM Prime Minister 2.5 okay most of you know it what is PM by the way PM means what is 2.5 and 10 then what is 2.5 and 10 here so the diameter diameter of what is 2.5 what kilometers microns right so whenever you are saying any physical quantity it has to have a unit attached to it so 2.5 and 10 microns are the diameter of the sphere in which that particle can accommodate okay minimum diameter of the sphere in which the particle can accommodate so you know very very dangerous PM 2.5 very very dangerous because you are you know it's not filtered while you breathe in so very difficult okay so these are harmful pollutants very good so all the top 10 people knew it except Raghav I believe everyone knew it okay next question how many words your city is divided into political question but you must be aware because after sometime I'm going to vote for these wards is it what is a ward by the way it's not hospital ward the entire municipal administrative area is divided into some areas yes how many so many people didn't know this there are 198 wards in Bangalore okay so each ward is represented by whom what is the name of that post operator very good and not on where do they sit where do they go where do what is the where is their office the municipal corporation yes very good and what do they do so what are the responsible for your local roads your electricity your drainage is not a headache of your central government or state government it is a responsibility of local municipality right people don't know and actually they blame the central government and state government for their local roads drainage and garbage collection and all that these are the responsibilities of local corporator or the municipal corporation right okay yes so now shuffling we are happening multiple number of times that's real fun let's see if you're really aware of these premier institutes of India which one is not in Bangalore Bangalore has a very good academic enrollment in terms of research and development in science and engineering which one is not there in Bangalore national chemical laboratory is not in Bangalore it is in Pune okay so most of you have got it correct good so NPR is there in Bangalore Rahman Research Institute is very much in Bangalore Indian Institute of Astrophysics is also in Bangalore but national chemical laboratory these are CSIR labs guys so national chemical lab about laboratories counsel for scientific and industrial research CSIR it takes care of industrial research and development in India multiple labs are there NPR also falls in there what you say administration okay okay so most see you are not aware of your city that's not cool you must be aware of your city okay so next is this this one which of the district borders Bangalore in which direction it is you must know in and out in and out about your city see lots of people and they go what is the awareness of my dear national public school children what is happening you are hot so you are aware of fortnight and abji's and model united nations but unfortunately you don't know about your neighborhood is Ramnagram between Tungkuru and Bangalore there is a another district called Bangalore rural okay so hence right so please be aware of your city leaderboard okay so good Ramnagar is the place where the I don't know have you heard of the movie Shole while going to Mysore oh it is there isn't it so Shole was shot in that place next question on your screen Google it quick Google my intention is even if you Google I don't mind learn but remember Google and remember these are not just to win any quiz you must learn also if you see three ask you everybody has what are the what are the districts can you tell me name name name manglore no manglore is not district my dear manglore falls in that Chinook a district that Chinook a Udupi Uttarakhand three Manipal is also not district Uttarakhand a Dakshin Kada and Udupi Uttarakhand after that Goa comes right so remember Goa Uttarakhand a Udupi then Dakshin Kada in which Mangalore famous fort of Mangalore is very famous for I am Kanadiga now come on here wherever you say you are for that place shallow very good maintain the lead next which of the following is now edible oil let me see who guesses who guesses or who can who knows it already very common very common sensible question let me see how many of you are aware really good yeah this is what the trap was yep so all cotton seed is also edible right so all three of them Google if you can Google Google shallow right so now palm oil rice bran oil cotton oil cotton seed oil all are edible that's what than we awareness see the awareness level now you can you can figure out that the very shuffling of the leaderboard can tell you how aware people are okay next awareness question but I think it is visible to you have you seen this somewhere see if you see your mobile phone it will be written over there not on the mobile phone as such on the package let me see okay okay so this was most of you have seen this this is related to European Union actually so they have come up with these standards on environment health and safety hazards safety standards right in Europe in European market mostly it is for it is actually for European market so if they are not see certified you cannot sell those product in those markets okay now it is also used across the globe so many people take that as a standard okay so you have seen this many times in electronic gadgets and other things show next yeah what happened oh my god what is this oh my god okay next come on come on come on use your phone this one is why is a safety match called a safety match have you ever explored why is a safety match called safety match safety safety pin why is it called safety pin oh cool most of you know it that's cool so safety matches is that until unless you know as it as you as you can figure out from you know so safety match so until unless you know deliberately this red phosphorus is put on the on the box so that until unless you match the stick with the box it will not light up automatically so that's why it is called safety match okay so you need to strike it against that right so hence good let me see oh my god oh my god oh my god yeah then so then it will be but safety match normally the temperature you're increasing the temperature no ashish if you put that in a flame it will automatically burn but it will not automatically burn in normal temperatures okay that ashish understood so Karun is leading have you done this experiment at home today you try this put on put on the gas burner and sprinkle some sodium chloride over it tell me the color you will get which color is it yellow yes so in chemistry later on you study no yellow yellow so later on you will see that sodium emits yellow like when bird sodium yeah I don't know if you have done this except have you have you ever explored this yes sir so hence you just do it today Monisha I don't believe Google do it and experiment yourself so you put it on a flame sodium sodium in the sodium chloride will emit yellow color okay I've done this and I'm saying okay never mind next see I've performed all of this experiments so if you check my Instagram and Facebook page you'll get the video of that is it okay okay so that's nice next hmm let me see how many of you are ready a vid a vid what is H.U.R.B. H.U.R.B. is books right so you don't know all of you read books what is ISBN stand for? Standout for book number okay Google says that great very good who issues ISBN where with which authority do you go to if you write a book explore that today okay here is the which authority gives you no God cannot be approached by mortal humans so far we have not we have we have not been able to crack that so sorry Monisha next yeah aksha is approached God today okay how many digits are there in ISBN this video should be easy Google it earlier there used to be nine so have you have you ever you know paid attention to these details guys hasn't no just tell me honestly anyone who knew it or anyone ever paid attention to figure it out anyone just just trust you know frankly tell me very honestly so that I could sense that whether you know or you knew I'm new okay not me I don't read books okay very good so there is a 13 letter 13 sorry 13 digit bar code is there yes it's always it will always be on the backside of the book very good show next guys enjoying or not all of you enjoying or not do you like do you like the quiz so cool people are aware about blood pressure okay what is blood pressure anyone what is blood pressure can anyone tell me pressure on what so which is the pressure of the blood applied applied to diversity effect of the atmospheric pressure on the body no dear this is the wrong wrong information what is blood pressure but he says arteries what is that arteries so see what happens is whenever a fluid so it's historic and diastolic oh these are all technical jargon's what is pressure pressure is for supplied per unit area correct now if there is pressure pressure in blood yes someone is saying come on go ahead it's pressure put by whom on what is the question very good so pressure put by the blood on the walls of the blood vessel is called blood pressure now blood vessels are not exposed to it on the other side so hence I know where you are explanation what money so that's the blood pressure is pressure applied by that's always remember it's not only blood which applies pressure whenever in your let's say washroom or in your plumbing circuits and water flows it applies some pressure on the walls of the duct every time a fluid flows across any duct it will apply pressure on the walls that's the fluid pressure in this case it is blood pressure right so very good now speak I don't know speak more manometer so manometer is usually used for measuring pressure okay so currently is still leading very good nice let's go to the next question let me now see you this one of very good let me see the awareness level right 120 by 80 millimeter hg what is the atmospheric pressure by the way guys ATM is the unit of one atmosphere is called 180 m so what is atmospheric pressure in mmhg so that means the pressure of the blood is lesser than atmospheric pressure and why are there are two numbers 120 and 80 which one is which one is the blood pressure or both are the blood pressure what is that 120 by Max and me is it so someone was mentioning systolic and diastolic so that's this so once the heart you know ventricle ventricle squeezes the blood out that's the highest pressure then it opens up it creates some kind of a vacuum and then blood flows in diastolic systolic right so understood now but tell me this this thing 120 by 80 that means you're saying the blood pressure is lesser than atmospheric pressure is that so yes or no if 760 mm is the atmospheric pressure then why is 120 by 80 mmhg what is the significance of 120 by 80 then why are we saying 120 mmhg when 760 mmhg is atmospheric pressure why is 120 mm the highest pressure now this is called gauge pressure guys please understand in physics gauge pressure means this is over and above atmospheric pressure so your blood pressure in absolute terms will be 760 plus 120 that is 880 mmhg of pressure is there in absolute terms but it so it is over and above atmospheric pressure but the point right so this is called gauge pressure right so it's over and above the atmospheric pressure oh most of you knew it already yeah that's nice good very good next question Tanya is already bored you must have seen this multiple number of times today also I had posted one very commonly used these days answer is Japan oh cool so people have a very good so the name of the person was Maha Hero Masha Hero Hara right 1994 was the year and the company was then so wave where he was putting these codes to identify components of vehicles and other other components in the shop floor Masha Hero Hara right what code that code was for some Wi-Fi okay I just picked it from Wikipedia okay cool let me see how many of you know this problem is you can do that also don't worry no problem have you ever thought of these things what is sim stand for how many if you actually knew it forget about you can Google that's okay but how many you actually knew it right now you know now you know right how do how does the mobile you know mobile towers identify you remember so subscriber identity module or identification module anything right so keep keep knowing keep knowing knowing is the final objective of this kind of session keep learning okay so very good so we'll now move a little faster Anika is in the first place now amount of rainfall is measured in let's say how many of you newspaper and are aware about it I'm out of rainfall is he spelling oh I don't think you're on mute right yes see people are not that aware it's measured in centimeters okay so area doesn't matter because whether it is two centimeters square or 20 centimeters square the height attained by water will be same isn't it so hence centimeters neither square centimeters not milliliters not millimeter cube you can you can also measure inches that's also done right how much India how much info does India get any idea around how much monsoon gets zero no 200 centimeter approximately around that no no no it varies place to place on an average 200 okay next only gandhar and aham fish go blah blah no knew it okay job very good next question this thing was in news recently why was it in news there is a company called space X and they it was the first non-government space agency which sent humans to ISIS first agency to do that said headed by a guy called Elon Musk right so not just that it was the first time in nine years US astronauts got to lift out of US by a US rocket because they didn't have a rocket they used to use the Soyuz rocket made by the Russians you know so one Indian actually perished what was the name I was preparing for my day then the day was second February 2002 so you must know all this great nice nice so let's go do so 400 kilometers orbit it looks majestic I don't know if you have seen what is some sunny Williams right what are what is the name Sunita Williams yes there's a very famous video of ISIS Sunita Williams video of life in ISIS go check it out on YouTube okay very good let's go to the next one in ISIS mmm let me see how many of you really are aware about it legit DK okay heat food yes microwave oven so magnetron is responsible for generating those microwaves okay so when a fluctuating microwave actually does what any polar molecule inside the food will start oscillating because of the microwave and when oscillation starts it starts you know the food resist the oscillation heat is developed and a very uniformly heated food material is obtained so microwave oven is the magnetron is present in the microwave oven yes oscillating waves correct so when the microwave hit those food particles the polar molecules start oscillating and that means okay cool next this is again you will study in grade 10 but you must know this very very common heating effects of current I gave the heat only induction cook top cook top right so you know the metal surface there are lots of current produced in the metal surface because of this induction the concept is called electromagnetic induction so there's a coil if you get a you know old induction cook top open it up and see there's a coil that coil creates magnetic you know electromagnetic induction in the vessel which is there kept on top current starts flowing it is resisted by the metal heat is produced and the food gets heated that's the fin funda next okay my right so lots of variations are happening that's nice next yes yes from Delhi the borders because my network went I'm sorry sorry sorry you can just reload no problem you will you'll be where you were I mean I don't have to work in itself so I have to escape of your versions oh oh oh I see sorry so this is your devices I am I am I holds for what is I am AI I am AI means mobile equipment identity okay so need a word so you try it and save it so it is used for anti-theft purposes if you know your I am I number if your phone gets stolen you can block the phone itself so it will become invalid the person who has stolen the phone cannot use it for making calls or any use but he can still take pictures I believe and he can use the Wi-Fi and all that but he can't make calls yeah this must be known to all of you if you are natives of Bangalore most of you would have been born here in Bangalore only so you must know who founded it right there is a famous you know okay airport name yes okay so most of you are no knowing this so I don't need to throw more light on this it was in 16th century by the way with where he did okay a night next who those three can't oh that I will not tell you now let me see this this much this one 50 in the registration plate denotes all of you would have seen this plate this kind of plate in your easy let's see many people do not know this right it's regional transport office so every city is divided into yes 0 2 or 0 3 is I think that place near Karpuram so everyone so K 0105 is yes good so that's how it is you yourself how many assembly constituencies are there in Bangalore city that means how many MLA's do you elect you don't elect we elect you will be electing after four years so by the time next I think next election will happen no not even next election next to next election you'll be able to in Bangalore city you must know this and you must also know who is your in which constituency you like you are located see people are not aware people are not aware at all people are not aware right there are 28 constituencies in your city you must know the name of your right constituency as well you must know your MLA's name you must know your constituency's name you must know your ward number all these are general awareness facts this is also important so Lok Sabha is for member of parliament how many member of parliament does Bangalore send every general election every five years right now how many MPs are there in Bangalore who are representatives of Bangaloreans this also oh see people are not really aware okay so three Bangalore north Bangalore central Bangalore south three constituencies are there for every constituency one MP is elected that is not in city Anika Bangalore ruler is outside city limits okay next so everybody knows this you must be aware these days required very much you must be trained at it as well last year we gave training on CPR I think we went to NPSHSR and Kormangula also where we using virtual reality we gave this training you know on what on Microsoft HoloLens it was amazing experience okay so many people know this cardiac arrest right so very good so it's an emergency not it's not a permanent and a very you know effective all the time solution it's for emergency just to you know supply air so that the depth of tissue can be delayed for some time that's it I don't know if you read newspapers so often would give chance to one person to explain what a CR is let me see your awareness level ah good you guessed it or you knew it what is cash is a ratio by the way it's the amount of what which is supposed to be at the bank like which bank the reserve bank where is this cash coming from investors and from the investors they get the cash and the cash like good who's speaking by the way I really like it who's this gandhar oh gandhar is there okay gandhar so the thing is when you put your money in the bank so what does bank do with that money they lend it to those people who require it for their business for farming whatever XYZ but they're not supposed to lend everything so if you if you give 100 rupees to your bank the bank is supposed to give those or keep it reserved for rupees right now it's around 4% I believe you have to just check the current rate you know rate so that much is kept reserved for all exigencies so they're not supposed to give everything out for other purposes so that's mandated by the agency called or the institution called Reserve Bank of India okay that's called cash reserve ratio it it impacts lots of macroeconomic factor like inflation interest rate and other things you'll get to know as you learn economics later on in this year okay so it is maintained next question oh sorry I could not show the net now I will see the this thing this is a good question I don't know if you're observant really observed it in how many languages 100 rupees is written on an Indian 100 rupees back note and you must also know how many scheduled languages are there in this country it's mentioned in oh most of you know it lots of people right good right yes 17 15 was there on the panel and two English and Hindi so in total 17 okay got it 15 was there in the panel Marathi Gujarati Odia Bengali Tamer Karada Malayalam Telugu all that okay and you must also know about the scheduled languages in this country it's mentioned in the constitution next question very close fight it is oh my god one wrong here and there and things will go topsy-turvy okay there is a nice question let's make you know this if you ever inquired about this why is stainless steel stainless what makes it stainless what do you do so what do you do for making it stainless good that oxygen and iron was not clicked by anyone but it is chromium around 11 percent of chromium is there in steel right so that it it uh fiddles with the reaction process of oxygen and iron and there is no rusting okay and my dear friends the last question of the evening be prepared before that the last leader board and do please give some feedback on the quiz on general awareness quiz so that we get some direction after the quiz is over so let's go for the last question guys last question is this before you go to bed or in the morning you gulp a glass full of milk you must know about 87 to 88 oh my god why why did you spoil it okay so many of you know that science is around four percent of fat four percent of proteins right and then lactose and then water so around when you next time you are drinking milk you're drinking water okay so here is the final leader board of the evening gandhar is on first position followed by raga amika nithin and this roshan and then tarun and drew and what aksha sujesh asi sujesh and roshni very very good congratulations gandhar well done i hope you enjoyed the quiz okay so please if you enjoyed the quiz write your specific feedback in mokstra if possible so that we could take your feedback and work on it right i hope this was good quiz for all of you did you guys enjoy the quiz was it useful for you did you learn something today did you learn something today did you know every question or you know one time i've had so sorry ahan do not get you okay do not get you ahan no it's really fun okay good thanks for that feedback so we will try to you know learn more such the thing so learning for you is be more aware so don't believe on things with you you know don't even believe on what you see also go beyond that try to figure out what is the reason behind whatever you are observing okay so that's how you build it's not a overnight process it will take a lot of time to be generally aware okay and if possible read one newspaper on a daily basis you will get to know so many other facts as well okay okay shadow by Lord thanks a lot enjoy we'll see you from tomorrow onwards in your regular classes and if possible drop in few lines in mokstra about the quiz thank you good night everything is available on youtube as well so the full playlist of all centimars are there if it is being updated so you can always go back to previous centimars thanks again guys thanks for your time good night and see you again bye
