Planet X has two moons orbiting in circular orbit around it. The mass of the first moon is twice the mass of the second moon. The radius of the circular orbit of the first moon is twice the radius of the second moon. If the first moon’s orbital velocity is 8000 m/s, what is the orbital velocity of the second moon?

A satellite is in circular orbit around an unknown planet. A second, different, satellite also travels in a circular orbit around this same planet, but with an orbital radius four times larger than the first satellite. Sue-Bob, the bad physics student, says: "The gravitational force of the planet depends inversely on the orbital radius squared. Since the second satellite's orbitai radius is four times that of the first satellite, the second satellite experiences on-sixteenth the gravitational force that is exerted...
