Which wave, A or B, has higher energy? A, because it has a higher amplitude
B, because it has a higher amplitude
A, because it has a lower amplitude
B, because it has a lower amplitude

How much work does the charge escalator do to move 2.30 μc of charge from the negative terminal to the positive terminal of a 3.00 v battery?
