Answer:
v = 350 m/s
Explanation:
The speed of sound depends on the temperature of surrounding. The relation between the speed of sound and the temperature is given by :
[tex]v=331+0.61T[/tex]
Where, T is temperature in Celsius
Here, T = 30 degree Celsius
[tex]v=331+0.61\times 30[/tex]
v = 349.3 m/s
or
v = 350 m/s
Therefore, the speed of sound in air at 30 degrees Celsius is 350 m/s.
