Planet X has 20 times the mass of the earth and 3 times the earth's radius. It orbits star Y at a distance of 8 AU, where 1 AU is the earth-sun distance. Star Y has twice the mass of our sun. (a) What is the orbital period of Planet X in years? (b) An astronaut has an earth weight of 120 lbs. What is her weight on the surface of planet X?

Samantha the astronaut visits planet X. She plans a low-tech experiment to do that will demonstrate basic physics concepts to kids watching at home. First, while still on Earth she makes a pendulum that will have a period of Length Next, she has a spring with k 25 N/m. She wants to have a mass hang from the spring and oscillate up and down with the same period. How much mass should she put on the spring? mass kg Samantha...

And most importantly, why?
Two spherical conductors are far apart. Both have the same positive uniform charge density on their surfaces. One sphere has a larger radius than the other. The larger sphere has (a) less total charge than the smaller sphere. (b) less electric potential than the smaller sphere. (c) less total potential energy than the smaller sphere. (d) None of the above.
