Question

4 rivers have the same vol. of h2o flow but fall from diff. heights to power dams. which dam would make the most power? dam d: fall height of 85 feet dam b: fall height of 55 feet dam c: fall height of 120 feet dam a: fall height of 250 feet

Explanation:

Step1: Recall power - height relation

The power generated by a dam is related to the height from which water falls (more height means more potential energy converted to electrical energy).

Step2: Compare given heights

We have dam A with 250 feet, dam B with 55 feet, dam C with 120 feet and dam D with 85 feet. Since 250>120>85>55.

Answer:

Dam A
