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) 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 . The potential energy of the water would be greater 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 greater at the bottom of the drop in the waterfall river A than at the hydroelectric dam in river \( B \).

Beyond the Answer
At the top of the drop in both rivers, the potential energy is the same since the height is identical. However, at the bottom of the drop, the kinetic energy differs due to the setup of the respective environments. In river A, as the water cascades over the waterfall, it rapidly loses potential energy, converting it into kinetic energy, creating a dramatic flow. Conversely, in river B, the water is harnessed by the hydroelectric dam, which can slow down the water flow to optimize energy conversion into electricity. Hence, the kinetic energy of the water would be less at the bottom of the drop in river A than at the hydroelectric dam in river B, as the dam’s design allows for a controlled and efficient energy extraction process.
