3. The answer is false

4. The answer is true

5. The answer is true

Explanation:

1. Because all renewable and nonrenewable energy sources are ultimately sourced from the sun, it is the primary source of energy on Earth. We obtain solar energy, which can be used for a variety of purposes. Hence the statement is true.

2. Since the force of friction goes against the direction that the ball is moving, Hence the statement is false.

3. Coal is an example of a nonrenewable source of energy. Hence the statement is false

4. Hydro energy is the largest source of renewable energy, which uses the natural flow of moving water to generate electricity. Hence the statement is true.

5. During the process of photosynthesis, solar energy is converted into chemical energy. Hence the statement is true.
