5. Solve the following examples.a. The specd of sound in air at 0 °C is332 m/s. If it increases at the rateof 0.6 m/s per degree, what will bethe temperature when the velocityhas incrcased to 344 m/s?(Ans: 200 °C)

Answer»

The speed of sound in air at 0℃ = 332m/s

If it increases at the rate of 0.6m/s per degree,

Speed at x℃ = (332 + 0.6x)℃

Thus 344 = 332 + 0.6x344 - 332 = 0.6x12 = 0.6xx = 12/ 0.6 = 20℃

Temperature is 20℃
