## 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 reasonable?

## Homework Equations

pressure (P)= force/area

area of sphere= 4[tex]\Pi[/tex]d[tex]^{2}[/tex]

density (

__p__)= mass/volume

## The Attempt at a Solution

somehow I'm assuming you're supposed to use the equation for the speed of a wave that includes force, which is V=[tex]\sqrt{T/\mu}[/tex]

but T=tension of the string. Since sound is not a wave on a string.. i am thoroughly confused.
