  1. Nov 25, 2008 #1
    Speed of sound at....

    1. The problem statement, all variables and given/known data

    find the values of the speed of sound in air at 30 degree.. Young modulus of cu=11 X 10^10 N/m^2 ,Bulk modulus of water=2.2 X 10^9 N/m^2 , density,p of copper=8.9 X 10^3 Kg/m^3 , density of water=1.0 X 10^3 kg/m^3

    2. Relevant equations

    do not have..sorry:frown:

    3. The attempt at a solution
    using formula of sound waves in gases v= square root of gamma . RT/M (ideal gas) but im stuck with M?:confused:
