A uniform wire, having a mass of 0.4 kg and length of 3.48 m, is connected to a pulse generator. The tension is maintained in the wire by suspending a 5.21 kg mass on the other end. Find the time (in s) it takes a pulse to travel from a pulse generator to the other end. Provide your answer in three sig. figures.
