What is the ratio of speed of sound in air when measured after laplace correction to that measured by Newton’s formula?(a) 1.18(b) 0.84(c) 1.4(d) 0.71
Right answer is (a) 1.18Explanation: By Newton’s formula v = √(P/ρ) & after laplace’s correction v = √(P/ρ), where is ratio of specific heats of air.The ratio of speeds = √γ.For air γ = 7/5& the ratio of speeds = √(7/5) = 1.18.
