Answer:
90 hp
Explanation:
Power = work / time
P = ½ (1500 kg) (25 m/s)² / 7.0 s
P = 67,000 W
P = 90 hp
The concept of power is given by the relationship between intensity and area, that is to say that power is defined as

Our values are given under the condition of,


The power is proportional to the Area, and in turn, we know that the Area of a circle is the product between
times the radius squared, therefore the power is proportional to the radius squared.

For both panels we would have to



Therefore the correct option is option C.9
Maybe because all of them come from natural elements (sun, air and water)
