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.
A) 260 m/s
B) 520 m/s
C) 1 040 m/s
D) 2 080 m/s
E) 4 160 m/s

Question

Quizplus · Accepted Answer

The velocity of a wave on a string is given by the formula v = sqrt(T/μ), where T is the tension and μ is the linear density. Substituting the given values, v = sqrt(1350 / 0.005) = sqrt(270000) = 520 m/s.
