Calculate the velocity of sound in a mixture of two gases obtained by mixing V_(1) and V_(2) volumes of them if the velocity of sound in them be C_(1) and C_(2) . The atomicity of the gases is the same.

Two monoatomic ideal gases 1 and 2 of molecular masses m^(1) and m​^(2) respectively are enclosed in separate containers kept at the same temperature. The ratio of the speed of sound in gas 1 to that in gas 2 is given by :-

Equal volumes of two immiscible liquids of densities rho and 2 rho are filled in a vessel as shown in figure. Two small holes are punched at depth h/2 and 3h/2 from the surface of lighter liquid. If v_(1) and v_(2) are the velocities of efflux at these two holes then ((v_(2))/(v_(1)))^(2) is
