Question

3) The speed of sound in air at 0°C is 332 m/s If it increases
at the rste of 0.6 m/s per degree, what will be the temperature
when the velocity has increased to 344 m/s?
​

Answer 1

0.6 afgos so easy to recite

Answer 2

Explanation:

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 + 0.6x

344 - 332 = 0.6x

12 = 0.6x

x = 12/ 0.6 = 20℃

Temperature is 20℃
