A.
According to the equation: v=λ*f
λ stands for wavelength. wavelength increases, the frequency will decrease. lower frequency deserves low energy.
A convex mirror makes a reflected light rays spread out.
Answer:
Sorry this isn’t going to be any help. You don’t have any statement that I’m able to see.
Explanation:
Answer:
There's one or two reasons, depending on what is meant by "wind-powered car".
