Question

What is the speed of sound at the atmospheric temperature of 30°C?

A. 340 meters/second
B. 341 meters/second
C. 349 meters/second
D. 300 meters/second

Answer 1

349.4 m/s

Step-by-step explanation:

Answer 2

Option C is the correct answer.

Step-by-step explanation:

The speed of sound in air is given approximately by

`v=331.4+0.6T_c`

Here
`T_c` is the temperature in degree Celsius.

Temperature
`T_c=30^0C`

Substituting we will get

v = 331.4 + 0.6 x 30 = 349.4 m/s

Option C is the correct answer.
