Answer: a. perigee speed

Explanation:

Firstly, we must define what is Perigee and Apogee:

The apogee is the point in an elliptical orbit around the Earth <u>where a body is furthest from the center of it and according to Kepler's 2nd law the speed of a satellite at this point is the lowest. </u>

On the other hand, the <u>perigee</u> is the opposite orbital point. <u>It is where a satellite is closest to Earth and its orbital speed is maximum. </u>

Therefore, if we want to throw an object in such a way that it is orbiting the Earth at the same distance respect to the ground, the minimum speed must be that which is in the perigee.

Elanso [62]
Salutations!

Describe the difference between revolution and a rotation, explain why each is important.

Revolution - Revolution is when the Earth revolves around the sun. This process takes 365 days/ 1 year.

Rotation - Rotation and revolution are both different. Rotation is when Earth is spinning on its own axis and also revolving around the sun. Rotation gives us day and night.

Why are they important?

Rotations gives us day and night which is 24 hours. Revolution gives us season. Earth's spins controls our live. We sleep at night and are awake in the days. Both of the spins are very vital to us.

Hope I helped (:
