Gravitational potential energy -> Kinetic energy -> Mechanical energy -> Electrical energy.

The water starts up (potential) and flows down (kinetic), the flowing water turns a big wheel (mechanical) which creates electricity (electrical).

Answer:

gravitational potential energy into kinetic energy into mechanical energy into electrical energy

Explanation:

Hydroelectric dam is used to convert gravitational potential energy stored in water to electrical energy. The water is stored at a height. As the water is releases, the gravitational potential energy converts to kinetic energy. The water is allowed to strike the turbine which starts rotating. Thus, kinetic energy is converted to mechanical energy. The turbine is connected to generator where mechanical energy is converted to electrical energy.

Thus, the correct sequence of energy transformation is: gravitational potential energy into kinetic energy into mechanical energy into electrical energy

The value of x in the given right triangle in a semicircle is determined as 21.

<h3>What is the measure of a triangle in a semicircle?</h3>

The triangle in a semicircle is always a right angle triangle.

From the figure shown, we can say that the triangle  G J K is right triangle and m<K = 90degrees.

Given that m<K = 4x + 6, we will can use the following equation to find the value of x as shown:

4x + 6 = 90

4x = 90 - 6

4x = 84

x = 21

Thus, the value of x in the given right triangle in a semicircle is determined as 21.
