Question 1

A piano string of density 0.005 0 kg/m is under a tension of 1 350 N. Find the velocity with which a wave travels on the string.

◦
260 m/s

◦
520 m/s

◦
1 040 m/s

◦
2 080 m/s

◦
4 160 m/s


Question 2

A piano wire of length 1.5 m vibrates so that one-half wavelength is contained on the string. If the frequency of vibration is 65 Hz, the amplitude of vibration is 3.0 mm, and the density is 15 g/m, how much energy is transmitted per second down the wire?

◦
21 W

◦
11 W

◦
5.4 W

◦
2.2 W
