The electromagnetic wave that delivers a cellular phone callto
a car has a magnetic field with an rms value of 1.5x10^-10 t. the
waves passes perpendicularly through an open window, the areaof
which is 0.20m^2. how much energy does this wave carry throughthe
windown during a 45s phone call? p=energy/time.

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.

Lightning is an example of what phenomenon? a release of a large amount of energy an absorption of a large amount of energy a natural electric circuit a natural electric current

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
