Question

If P is the pressure of a gas and p is its density,then find demension of velocity in terms of P and p

Answer 1

Pressure =F/A Dimension Of Force=MLT^-2 Dimension of area=L^2 PRESSURE=MLT^-2/L^2=ML^-1T^-2  Formula of density =mass/volume Mass dimension is M and volume is L^3 DENSITY =ML^-3. SO DIMENSION OF VELOCITY =L^T^-1
