Question

Four rivers have the same volume of water flow over time but fall from different heights to power hydroelectric dams. Which dam would provide the most hydroelectric power? (1 point)
• dam B: fall height of 75 feet
• dam C: fall height of 135 feet
• dam A: fall height of 175 feet
• dam D: fall height of 100 feet

Answer 1

The power generated by a hydroelectric dam is directly proportional to the height of the fall. Therefore, the dam with the highest fall height, dam A with a fall height of 175 feet, would provide the most hydroelectric power.
