Homework Help: What is the wave speed in a brass wire

  1. Jan 24, 2010 #1
    1. The problem statement, all variables and given/known data
    What is the wave speed in a brass wire with a radius of 4.65×10-4 m stretched with a tension of 128 N? The density of brass is 8.60×103 kg/m^3.

    2. Relevant equations

    v=square root of T/u

    3. The attempt at a solution

    I have already found the cross sectional area but am unsure of what to do from there.
