the surface of Planet X where the object's
weight is measured to be 20 N. The radius
of the planet is 4.0 x10^6 m. What is the
mass of Planet X? (G = 6.67x10^-11 N
m*2/kg^2) *
O 13x1019 kg
O 17x10^22 kg
9.6x10^24 kg
O 21x10°25 kg
There is a planet X that has a mass that is 24 times that of the earth and 4 times the earth's raidus. It orbits a star Y at a distance of 12 AU. (1 AU is the earth sun distance). Star Y has a mass 3 times that of our sun.What is the orbital period of Planet X in years?If an person has an earth weight of 140 lbs, what is it's weight on the surface of planet X?
