Two wires are parallel, and one is directly above the other. Each has a length of 55.8 m and a mass per unit length of 0.0260 kg/m. But, the tension in wire A is14.6×102 N, while the tension in wire B is 2.31×102 N. Transverse wave pulses are generated simultaneously, one at the left end of wire A and one at the right end of wire B. The pulses travel toward each other. How much time does it take until the pulses pass each other?
