A city gets its electricity from a dam, where water is stored in a reservoir. How does the water provide the city with its power?(1 point) Responses Potential energy in the water becomes kinetic energy as it moves through turbines, which turn kinetic energy into mechanical energy that spins a generator, which changes mechanical energy into electricity. Potential energy in the water becomes kinetic energy as it moves through turbines, which turn kinetic energy into mechanical energy that spins a generator, which changes mechanical energy into electricity. Chemical energy in the water becomes thermal energy as it moves through turbines, which change thermal energy into electricity. Chemical energy in the water becomes thermal energy as it moves through turbines, which change thermal energy into electricity. Kinetic energy in the water becomes potential energy as the water moves through turbines, where kinetic energy becomes mechanical energy that spins a generator. Kinetic energy in the water becomes potential energy as the water moves through turbines, where kinetic energy becomes mechanical energy that spins a generator. Mechanical energy in the water is transferred to turbines that spin a generator, which changes the mechanical energy into electricity.

The correct response is: Potential energy in the water becomes kinetic energy as it moves through turbines, which turn kinetic energy into mechanical energy that spins a generator, which changes mechanical energy into electricity.
This describes the process accurately, starting with the potential energy of the stored water in the reservoir, which is converted to kinetic energy as it flows down, and then transformed into mechanical energy to generate electricity.
