11. Of all the planets in our solar system, Jupiter has the greatest gravitational strength.

a. If a 0.5 kg pair of running shoes would weigh 11.55N on Jupiter, what is the strength of gravity there?

 

b. If the same pair of shoes weights 0.3N on Pluto, what is the strength of gravity on Pluto?

 

c. What is the weight of the shoes on Earth?

my science fair project is do in a week helppppppppppppppllllllllllllleeeeeeeeeeeaaaaaaaaaaassssssssssseeeeeeeeeeeeee

Here's a link to the question..I have the first one correct butcan't seem to figure out the second question.

There's also another question..
http://capa2.phy.ohiou.edu/res/ohiou/ccliphys/dcCircuits/resistors/05_res_series_3equal.problem

I can't seem to figure out the last two questions. They're all verysimilar so I'm guessing there's a pretty main concept that I'mmissing.

PLEASE HELPPPP!

Once i get to the 1... and .....2 equations at the end, how doisolve for the xsin theta and x cos theta when i can't solve foroneand put it in the other equation to solve im so confusedpleasehelppp
