AI Generated Solution

To explain why an artificial satellite, in the presence of frictional forces, will move into an orbit closer to the Earth and may have increased kinetic energy, we can break down the explanation into several steps: ### Step-by-Step Solution: 1. **Understanding the Initial Conditions**: - An artificial satellite is in orbit around the Earth. In a stable orbit, the gravitational force acting on the satellite provides the necessary centripetal force to keep it in motion. 2. **Effect of Frictional Forces**: ...
