The linear density of a string is 5.520×10-3 kg/m. A transverse wave on the string is described by the equation y=(0.033 m)sin(2.50 m-1x +125.7 s-1 * t). 1.) What is the wave speed? 2.) What is the tension in the string??? I've already calculated the wave speed but I don't know how to do the tension in string! HELP PLS!
