Answer 1

The correct option is D Balancing the earth's gravity

An artificial satellite is a man made object that is launched from Earth's surface, and is made to revolve around the earth. Man made satellites are used for many purposes:

• Weather forecasting
• Remote sensing
• Transmitting radio and TVsignal
• Telecommunication
• Defense and military, etc.

However, it is impossible for a man made satellite to balance or regulate the earth's gravity.
