Question

A string of mass 5 g and length 1.25 m is tightly attached to a mechanical vibrator at one end and to a fixed support at the other end. The mechanical vibrator generates traveling waves. The traveling wave is modeled with the wave function y = 6 mm (sin { [1.5π (rad/m) x] + [90π (rad/s) t] } ). What is the i) tension (T) in the string and the ii) average power (P_av) transmitted by the traveling wave?

Accepted Answer

i) T = 14.4 N; ii) P_av = 0.345 W

Answer

i) T = 14.4 N; ii) P_av = 3.45 W

Answer

i) T = 144 N; ii) P_av = 0.345 W

Answer

i) T = 144 N; ii) P_av = 3.45 W
