Given:
The energy in the river is converted into electrical energy
To find:
What type of energy is in the river that is changed to electrical energy?
Explanation:
The water of the river is generally stored by creating a dam. The turbine is moved by the kinetic energy provided by the water of the river when the lock gate is opened.
So, the potential energy and the kinetic energy change into electrical energy.
Hence, potential and kinetic energy both change to electrical energy which is the option (D) is correct.
