The velocity of sound in air `(V)` pressure `(P)` and density of air `(d)` are related as `V alpha p^(x) d^(y)`. The values of `x` and `y` respectively are

The ratio (V) of velocities of sound in dry air and humid air is -

The velocity (v ) of sound in a gas depends on the pressure (p) and density ( sigma ) of the gas. Using dimensional analysis establish a relation between v,p and sigma .

Assume that the speed (v) of sound in air depends upon the pressure (P) and density rho of the air and use dimensional analysis to obtain an expression for the speed of sound.

The velocity of sound is v_(s) in air. If the density of air is increased to 4 times, then the new velocity of sound will be

The velocity of sound is v_s in air. If the density of air is increased to 4 times, then the new velocity of sound will be
