Question

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)
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.
chemical energy in the water becomes thermal energy as it moves through turbines, which change thermal 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

Explanation:

• When water is stored in a reservoir, it has potential energy due to its height.
• As the water moves through turbines, this potential energy is converted into kinetic energy (energy of motion).
• The kinetic energy of the water causes the turbines to spin, which is a form of mechanical energy.
• The spinning turbines then spin a generator, and the generator converts this mechanical energy into electrical energy.

Answer:

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.
