Question by 🙂: Science/Physics Help, A.S.A.P.!?
1)Find the change in the force of gravity between two planets when the masses of both planets are doubled and the distance between then stays the same.
2)Find the change in the force of gravity between two planets when the masses remain the same, but the distances between them is increased by a factor of 10 times.
3)Find the change in the force of gravity between two planets when the distance between them is decreased by a factor of 10 times.
9)The moon is about 3.8 x 10^8 M away from the earth and has a period of 27.3 days. What is the orbital speed of the moon around the earth in M/S? (Hint: First calculate the period of the moon’s orbit in seconds).
The equation is: V= 2 π R/ T (T=Period & R=Radius. /=over/divided by).
