Answer:
initial speed of sound at 30 degree C
\(v_1 = 349.6 m/s\)
final speed of sound at 36 degree C
\(v_2 = 353.2 m/s\)
Explanation:
As we know that velocity of the sound in air is given by the formula as
\(v = 331.6 + 0.6 t\)
here we know that
t = temperature or air in degree celcius
so here at 30 degree celcius we can say that
\(v_1 = 331.6 + 0.6(30)\)
\(v_1 = 349.6 m/s\)
now at 36 degree C the speed of sound is given as
\(v_2 = 331.6 + 0.6(36)\)
\(v_2 = 353.2 m/s\)
