Answer 1

Answer:

The equation for the speed of sound in air v = √γRTM 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≈331m/s√T273K.

The speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.

What evidence can you give that the speed of sound in air does not depend significantly on frequency? Listening to music while seated far away from the source of sound gives evidence that the speed of sound in air does not depend on frequency.

Answer 2

THE ANSWER IS:-

Calculation of minimum distance to hear an echo

Calculation of minimum distance to hear an echoOur distance from the sound reflecting surface should be 17.2 meters in order to hear an echo in air at a temperature of 20 degree.
