A sinusoidal wave of angular frequency 1230 rad/s and amplitude 3.00 mm is sent along a cord with linear density 2.40 g/m and tension 1232 N. (a) What is the average rate at which energy is transported by the wave to the opposite end of the cord? (b) If, simultaneously, an identical wave travels along an adjacent, identical cord, what is the total average rate at which energy is transported to the opposite ends of the two cords by the waves? If, instead, those two waves are sent along the same cord simultaneously, what is the total average rate at which they transport energy when their phase difference is (c) 0, (d)0.5π rad, and (e)ì rad?

A sinusoidal wave of angular frequency
1230 rad/s and amplitude 3.00 mm is sent
along a cord with linear density 2.40 g/m
and tension 1232 N. (a) What is the
average rate at which energy is
transported by the wave to the opposite
end of the cord? (b) If, simultaneously, an
identical wave travels along an adjacent,
identical cord, what is the total average
rate at which energy is transported to the
opposite ends of the two cords by the
waves? If, instead, those two waves are
sent along the same cord simultaneously,
what is the total average rate at which they
transport energy when their phase
difference is (c) 0, (d)0.5π rad, and (e) rad?
