Question

The Hoover dam is a hydroelectric power plant that converts the energy of falling water into electricity. Which of the following determines the amount of potential energy of the water stored in the reservoir of the dam? Choose all that apply.
A.the electric potential energy of the water. B. the weight of the water C.the height of the water D. The temperature of the water (I think it's A and C but I'm not sure)

Answer 1

The correct answer to the question is : B) The weight of the water, and C) The height of the water.

EXPLANATION :

Before coming into any conclusion, first we have to understand potential energy of a body.

The potential energy of a body due to its position from ground is known as gravitational potential energy.

The gravitational potential energy is calculated as -

                      Potential energy P.E = mgh

 Here, m is the mass of the body, and g is the acceleration due to gravity.

h stands for the height of the body from the ground.

We know that weight of a body is equal to the product of mass with acceleration due to gravity.

Hence, weight W = mg

Hence, potential energy is written as P.E = weight × height.

Hence, potential energy depends on the weight and height of the water.

Answer 2

Answer would be: B & C
Potential energy = weight * height

Hope this helps!
