A wave is traveling at 35 m/s on a string with a linear density of 0.082 kg/m. What is the tension in the string?
A)0.28 N
B)0.56 N
C)2.5 N
D)5.0 N
E)10 N

Question

Quizplus · Accepted Answer

The wave speed v on a string is given by the formula v = sqrt(T/μ), where T is the tension and μ is the linear density. Rearranging for T gives T = v^2 * μ. Substituting the given values, T = (35 m/s)^2 * 0.082 kg/m = 100.45 N, which rounds to 10 N.
