    Waves & Sound: Combine Pressure & Density to Produce Dimensions of Speed

    how about.. \sqrt{P/\rho} so that \sqrt{(M/LT^{2})/(M/L^{3})} which equals L/T

    Waves & Sound: Combine Pressure & Density to Produce Dimensions of Speed

    Well, since dimensions of speed are meters/second- It seems as if the density equation would need to be flipped to 1/\rho which is equal to L^{3}/M so the masses cancel out but I'm not sure how you can equate pressure and density.. ?

    Waves & Sound: Combine Pressure & Density to Produce Dimensions of Speed

    Homework Statement Two important quantities associated with air are the pressure and density. How can the pressure and density be combined to produce dimensions of speed? Look up the pressure and density of air at sea level and use your equation to estimate the speed of sound. Is your answer...
