What is multiplying the amps (I) by the volts (V)?
400
A clothes dryer uses about 27 amps of current from a 240-volt line. How much power does it use?
What is P=IxV = 240V x 27A = 6500 Watts
500
The intensity of a wave does this as a material being hit by the wave moves farther away from the source of the wave.
