Two different rivers have drops that are the same height. In river A, this section of the river is a waterfall. In river B, this section has a hydroelectric dam. In what way does the energy 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 river A than in river B.
The potential energy of the water would be greater at the top of the drop in river A than in river B.
The kinetic energy of the water would be less at the bottom of the drop in river A than in river B.
The potential energy of the water would be less at the top of the drop in river A than in river B.
The turbines can be seen inside this hydroelectric dam. Why are they located at that particular height?

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