Mars has a mass of about 6.4 X 10^23 kg, and its moon Phobos has a mass of about 9.6 X 10^15 kg. If the magnitude of the gravitational force between the two bodies is 4.6 X 10^15 N, how far apart are Mars and Phobos?

A simple pendulum consists of a 3 kg point of mass hanging at the end of a 2 m long light string that is connected to a pivot point. a. Calculate the magnitude of the torque (due to gravitational force) around this pivot point when the string makes a 5 de...

How is it possible for gravitational potential energy to be negative? I Googled the answer, but all I could understand was that if the PE was zero at infinity as you move toward an object with gravity the KE must be positive because KE is the energy of mo...

simplify the fraction 4t to the second power-16 over 8 over t-2 over 6

Thanks a lot, we didn't get that formula. That might be why I was having problems. :)

Okay, so using the ground level for your reference point if you went under the crust the GPE must be negative for the total energy to remain zero? I think I get it! Thanks a lot!

yes it is Michael Jackson!

m=mols/L first, get the no. of moles. n=wt/mw where n = no. of moles wt = weight mw = molecular weigth n = 5.0g / 40 g/mol cancel the grams, so the left unit is mol. Ans. n=0.125mol You can now get the molarity of the solution, m = n/L where m = molarity...

Glitch is correct.
