    wave speed
    consider that a wave is traveling with speed v through a long string of mass density M stretched by a tension T What is the numerical value of v/root(T/M) in the cgs system of unit of measurement and in the matric system?

    The wave velocity in a string is proportional to the square root of (tension divided by mass density):



    So v divided by must equal 1, and is unitless.
