Asteroid a has a mass of 7.50×1020 kilograms (kg), and asteroid b has a mass of 7.10×1018 kg. assuming that the same force was applied to both (a shock wave from a supernova, for example), what would be the ratio of a’s acceleration to b’s acceleration?

how many times greater is the force of gravity on a 5 kg object lying on the surface of a moon than on a 5 kg object orbiting at a distance of 1 moon radii above the surface?

what is the mass, in msun, of a star observed to have a planet with an orbital radius of 2.00 au and a period of 4.00 years?

what is the ratio of the orbital velocities of two satellites, each in circular orbit around earth, given that satellite a orbits 3.40 times as far from earth’s center of gravity as satellite b? give your answer in terms of b’s velocity to a’s velocity.
