2. A cord with linear mass density 14 g/m carries a traveling transverse wave moving in the +x- direction. The transverse displacement of the cord at any position x along its length at time t is given by the function y(x) = (7 mm) sin[(0.4 m^-1)x - (12 s^-1)t]. What is the magnitude of the tension in the cord? a) 10.8 N b) 12.6 N c) 13.5 N d) 14.4 N e) 16.2 N
