Answer:
The velocity of wave is 0.25m/s
Explanation:
First, you have to find the fequency using the formula, F = 1/Time :
Let t = 2s,
Next, you have to use speed formula, V = f×λ :
Let f = 0.5Hz,
Let λ = 0.5m,
When an experiment happens in the USA and the test of the world read it conversions may go wrk v and think that the experiment is false
D. Wind turbines, because wind is a renewable resource while all the other options use non renewable resources.
