What are the directions of rotation of a polar satellite and the Earth?

If the mass of a satellite is doubled and the time period remains constant,the ratio of the orbital radii in the two cases will be:

The period of a satellite in a circular orbit around a planet is independent of

Two satellites $A$ and $B$ revolve around the same planet in coplanar circular orbits. Their periods of revolution are $1\, h$ and $8\, h$,respectively. The radius of the orbit of $A$ is $10^{4}\, km$. The speed of $B$ relative to $A$ when they are closest is (in $km/h$):

Suppose an astronaut throws a spoon out of a spacecraft. Will the spoon fall to the Earth?

$A$ satellite $S$ is moving in an elliptical orbit around the Earth. The mass of the satellite is very small compared to the mass of the Earth.
