Physics Tutorial Lesson: Keplers 3rd Law Planets Help College High School

[BboyaRze]

hold on, if T^2 is directly prop to R^3 then surely T^2 / R^3 = k not what you have wrote, (the other way round) ? please answer quick

[MrChimei]

@BboyaRze If T^2/R^3 = k then R^3/T^2 = 1/k (denoted here as k, rightly so as it is also a constant). What this means is that you can use either T^2/R^3 or its reciprocal, and solve using a constant. I hope this helps.

@MrChimei Thanks bru, this was giving me problemo's

@irronjuan Hi. Sorry about that we are always trying to improve. I hope the video was still helped.

when you name your video kepler's 3rd law, first you should show how to prove it, why it is true.

How high up is a geostationary satellite? Given that a satellite that orbits 200 miles above the Earth’s surface has a periodic time of 90 minutes and the diameter of the Earth is 7926 miles

[mcaruana1]

@fredeck19 Hi. You stated that the satellite is 200 miles above the earth but the question was how high is a geostationary satellite. A geostationary satellite is 35,000 km or 21,700 miles above the earth. I'm not sure what the given info of 200 miles is for. Also a geostationary satellite has a period of 24 hours so I think there is a problem with the question. I hope this helps.
