    Energy and rate of energy transmitted by a given wave function

    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...

    Waves: finding the tension of a cord

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

    Waves: finding the tension of a cord

    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 ---...
