1.	Give the expression for the velocity of sound in air // gaseous media along with the meanings of the symbols used.
Answer» <P> Solution :Velocity of the speed`v = sqrt((gamma p )/( rho ))` where` gamma = `is ratio of MOLAR specific HEATS of a gas, p - pressure on gas and `rho -` DENSITY of GASEOUS medium.
