Consider a thin metal rod that carries an excess charge of 45 nC. The rod is 1.5 m long. The left end of the rod is found to be at a potential of 35 V, with respect to an established 0 V reference. What is the electric potential at the other end?

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
