right anwser???

Answer 1

The correct answer is: to ensure that the water does not lose too much potential energy before reaching the turbines.

Answer 2

A child is swinging back and forth on a swing. Changes in her kinetic and potential energy are happening each moment. At which point, or multiple points, in her swinging would each of these two types of energy be at a maximum? In one to two sentences, describe these points and which type of energy is at a maximum at each point.(2 points)
whats the anwser

Answer 3

The maximum potential energy would occur at the highest points of her swinging motion, when she is at the furthest point away from the ground. The maximum kinetic energy would occur at the lowest points of her swing, when she is swinging the fastest.

Answer 4

An athlete is practicing shotput using a 16-pound shot, and he throws it 40 feet. He then uses a 12-pound shot and throws it 50 feet. In three to four sentences, explain why there is a difference in these throws using the ideas of mass and speed and how each relates to kinetic energy.(4 points)
whats the right anwser

Answer 5

The difference in throws can be explained by the concepts of mass and speed and their relation to kinetic energy. The athlete throws the 16-pound shot a shorter distance because it has greater mass, which requires more force to accelerate and launch. The 12-pound shot, with less mass, can be thrown a longer distance as it requires less force and can achieve greater speed. The speed contributes to the greater kinetic energy of the 12-pound shot, enabling it to travel farther.
