But it is unreliable. The wind is the motion of air from high pressure region to low pressure region. Thus, we cannot start or stop wind turbines to spin. It depends on the wind and its speed.
Answer:
Explanation:
Energy of a wave is proportional to ( amplitude )²
it is also proportional to ( frequency )²
It is proportional to velocity
Here velocity is constant
energy of wave ∝ ( amplitude )² x ( frequency )²
So, option C a high amplitude and a high frequency is correct .
