2. Two different rivers have drops that are the same height. In river A, this drop of the river is a waterfall. In river B, this drop has the generator for a hydroelectric dam. In what way does the energy of the water differ between the drops in the two rivers?(1 point)
Responses
The potential energy of the water would be less at the top of the drop in the waterfall river A than at the hydroelectric dam in river B.

The kinetic energy of the water would be less at the bottom of the drop in the waterfall river A than at the hydroelectric dam river B.
3. Use the diagram to answer the question.
The water in the dam is stored at the top. This stored water flows into the turbine, causing it to rotate. The turbine, in turn, rotates the shaft of a generator that produces electricity.
The turbines can be seen inside this hydroelectric dam. Why are they located at that particular height?
