Answer:
All of us know that the earth is rotating continuously in its orbit. But we dont realize the rotation due to gravitational force. The earth rotates in its own axis this causes day and night . While rotating on its axis, earth also rotates around elliptical axis around the sun which causes the different regions to experience different seasons. The side facing the sun experience summer and other side experience winter.
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.
