Answer 2

SOLUTION

GIVEN

The velocity of sound is 330m/s at 0°C

TO DETERMINE

The velocity of sound at 40°C

EVALUATION

Here it is given that the velocity of sound is 330 m/s at 0°C

We have to find the velocity of sound at 40°C

We know that Speed of sound varies with temperature. It increases with increase in temperature. The speed of sound increases by 0.61m/s per degree rise in temperature

This gives

The velocity of sound at 40°C

= 330 + ( 40 × 0.61 ) m/s

= 330 + 24.4 m/s

= 354.4 m/s

FINAL ANSWER

The velocity of sound at 40°C = 354.4 m/s
