According to Laplace's formula, the velocity (V) of sound in a gas is given by `v=sqrt((gammaP)/(rho))`, where P is the pressure and `rho` is the density of the gas. What is the dimensional formula for `gamma` ?

It P is the pressure and rho is the density of a gas, then P and rho are realted as :

If P is the pressure and rho is the density of a gas, then P and rho are related as :

If V=sqrt((gammaP)/(rho)),V =velocity, P= pressure rho = density, then dimension of gamma will be …….

The dimensions of gamma in the relation v = sqrt((gamma p)/(rho)) (where v is velocity, p is pressure , rho is density)

The corrected Newton's formula for velocity of sound in air is v=sqrt((gamma P)/(rho)) , where P is pressure and rho is density of air, gamma =1.42 for air. At normal temperature ane pressure, velocity of sound in air =332m//s . Read the above passage and answer the following question: (i) How do the sound horns protect us from the oncoming vehicles ? ltbr. (ii) How does a sand scorpion fing its prey? (iii) Will the velocity of sound in air change on changing the pressure alone?

If P is the pressure of a gas and rho is its density , then find the dimension of velocity in terms of P and rho .
