Answer:
She is making kinetic energy when she lifts the ball and when the ball is above her head the ball gains potential energy.

This would be 'chemical' weathering.
Acid rain would react with the minerals in the rocks, causing them to break down.

Answer:
19.6 J
Step-by-step explanation:
Before the ball is dropped, it has a <em>potential energy
</em>
PE = mgh
PE = 0.2 × 10 × 9.8
PE = 19.6 J
Just before the ball hits the ground, the potential energy has been converted into kinetic (<em>mechanical</em>) energy.
KE = 19.6 J
True but in more depth they both have the some same qualities in function but provide for each other when one makes oxygen, H2O, and energy and cellular respiration makes CO2 and glucose
