Answer:
b. amplitude
Explanation:
An electromagnetic waveconsists of electrical oscillations and magnetic fields. The frequency of the wave is directly proportional to its energy and its speed and inversely proportional to its wavelength. Therefore, with the only magnitude with which it has no relation is with its amplitude.
B i believe that is your answer
Answer:
Power, P = 480 W
Explanation:
It is required to find the power used by 4 A appliance that is plugged into a 120 V circuit for 4 minutes. Power used by an appliance is given by the formula as follows :

Plugging all the values we get :

So, the power used by the appliance is 480 W.
