A string has a tension of 100.0 N and a wave speed of40.0 m/s when it is plucked. What is the linear densityof the string?
Question
Solution 1
The wave speed v on a stretched string depends on the tension F and the linear mass density μ (mass/length) of the string. This relationship is given by the formula:
v = sqrt(F/μ)
We can rearrange this formula to solve for the linear density μ:
μ = F/v²
Given that the tension F is 100.0 N and th Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
