# Problem: The wave speed on a string under tension is 250 m/s.Part A. What is the speed if the tension is halved?Express your answer with the appropriate units.

###### FREE Expert Solution

In this problem, we need the expression of the velocity of a wave in a string.

Velocity:

$\overline{){\mathbf{v}}{\mathbf{=}}\sqrt{\frac{\mathbf{T}}{\mathbf{\mu }}}}$ where T is the tension and μ is the mass per unit length (m/L).
