Question

derive a expression for speed of sound​

Answer 1

Explanation:

$answer}$

The equation for the speed of sound in air v=√γRTM v = γ R T M can be simplified to give the equation for the speed of sound in air as a function of absolute temperature: v=√γRTM=√γRTM(273K273K)=√(273K)γRM√T273K≈331ms√T273K. v = γ R T M = γ R T M ( 273 K 273 K ) = ( 273 K ) γ R M T 273 K ≈ 331 m s T 273 K . v=fλ.

Answer 2

here it is dmdt=ddt(ρV)=ddt(ρAx)=ρAdxdt=ρAv.
