A sound source sends a sinusoidal sound wave of angularfrequency3000 rad / s and amplitude 12.0 nm through a tube of air. Theinternal radius of the tube is 2.00 cm. (a) What isthe average rateat which mechanical energy is transported to theopposite end of thetube? If an identical wave and theoriginal wave travelalong the tube simultaneously, what is thetotal average rate atwhich they transport mechanical energy to theopposite end of thetube when their phase difference is (b) 0, and(c) 0.40 Ï rad?
