naaaahhh! Cummon! U dint make me crazy (I always am don worry :whistle: :ROFL:) i'm just sad i cant explain it :( -

*uuugghh* I dunno how to explain this way :( I only know how i did it :( n naahh! Ur doing awesome ;) -

well, imma right it just like what I wrote there :P U have done it right BUT u need to bring the 400 up, thats taken as a reciprocal too :) -
Physics Unit 4 JUNE 11/6/12
Its not wrong... i umm.. dunno how to do it ur way :oops: I jst did it by reasoning it... If it is 400 times less mass, then divide by 400 (inversely related) , if it is 15 times nearer, then multiply by 15^2 (directly related) 225/400 = 9/16 :) -

Yup! But even the 400 needs to go up ;) -
Physics Unit 4 JUNE 11/6/12
meaning? U need to make it 1/225 in the denominator, so it comes up n becomes 225 while u take the 400 down :) -
Physics Unit 4 JUNE 11/6/12
yes it is ;) I did it just like I wrote it there :P n yeah u need to take a reciprocal cuz its inversely proportional :) -
They were worth it ;) N thank you :D
They were worth it ;) N thank you :D- étudiante

u can substitute an do it, but why do the hassle when u can use simple ratio :p But either way is fine IF u dont mess up where u substitute the numbers ;) btw.. confirm my answer pls... m not completely sure... -

In Q58 which part do u wanna know? The last part is just that we need to put both the fields equal, and find R like GM/R^2 = Gm/r^2 and then solve for R :) for this 1 we need to use g = GM/r^2 so 400 times less massive means mass is less by 400 but r is inc by (15)^2 ; 225/400 = 9/16 (is that... -

U think? :rolleyes: :P I'd be jumping about if I had :P I have Astrophysics left still, the Stars Life cycle part and a bit of gas laws... wat abt u? :)
