An artificial satellite orbiting around the earth does not fall down. ...
Explanation:

An artificial satellite is an object placed into orbit around the earth. It is able to stay in orbit because of the earth's gravitational pull. The force of gravity is what keeps the satellite in orbit around the earth.

The correct option is D i.e. "Provides the necessary acceleration for its motion". This is because of the following reasons:

1. Centripetal force: The satellite is always accelerating towards the earth due to the force of gravity. This is known as centripetal force. The satellite is constantly changing direction but its speed remains constant. This is because of the centripetal force which acts perpendicular to the velocity of the satellite.

2. Balanced forces: The force of gravity is balanced by the force of the satellite's motion. The satellite is moving forward at a constant speed, which creates a force equal and opposite to the force of gravity.

3. Escape velocity: The satellite is moving at a speed that is higher than the escape velocity of the earth. The escape velocity is the minimum speed required for an object to escape the gravitational pull of the earth. The satellite is moving fast enough to overcome the force of gravity and stay in orbit.

Conclusion:

In conclusion, the artificial satellite is able to stay in orbit around the earth because of the force of gravity and the necessary acceleration provided by the earth's gravitational pull. This acceleration is what keeps the satellite in motion and prevents it from falling towards the earth.
