Answer:
Power of the string wave will be equal to 5.464 watt
Explanation:
We have given mass per unit length is 0.050 kg/m 
Tension in the string T = 60 N 
Amplitude of the wave A = 5 cm = 0.05 m 
Frequency f = 8 Hz 
So angular frequency 
Velocity of the string wave is equal to 
Power of wave propagation is equal to 
So power of the wave will be equal to 5.464 watt
