1. The wave function for a wave on a taut string is given below, where x is in meters and t is in seconds. y(x, t) = (0.300 m) sin(11πt - 3πx + π/4) (a) What is the average rate at which energy is transmitted along the string if the linear mass density is 75.0 g/m? (b) What is the...

That was all my problem was, thanks!

that's a good question, that hadn't occurred to me. I'll give that a try

1. A telephone cord is 3.95 m long and has a mass of 0.180 kg. A transverse pulse is produced by plucking one end of the taut cord. The pulse makes four trips down and back along the cord in 0.790 s. What is the tension in the cord? d=3.95m, m=0.18kg, 4t=0.79s2. v=(T/u)^0.5 --- v2=T/u ---...
