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 kinetic energy of the water would be greater at the bottom of the drop in the waterfall river A than at the hydroelectric dam in river B.

The turbines can be seen inside this hydroelectric dam. Why are they located at that particular height?

There is a large drop, so the water will have a lot of potential energy to transfer to the turbine.

There is a small drop, so the water will still have a lot of potential energy to transfer to the turbine.
