Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
Genetic variation is an effect

Answer:
Due to sloppy nature of the field.
Explanation:
This problem of rapidly drainage can be solved if the field should leveled because the portion is rapidly drained due to sloppy nature of the field. Sloppy nature of land moves water at the faster rate from higher elevation to lower elevation. We can see in tillage practices, the farmers used levelers in order to level the field in order to provide even resources such as fertilizers and water. So we can say that this problem can be solved if the field will be leveled.
