Your boss asks you to adjust the temperature so that a sound wave travels more quickly through the air. You increase the tempera
2 answers:
Answer:
A) 352.6 m/s
Explanation:
As we know that velocity of sound in air at given temperature is given by the formula
here we know that
t = temperature in degree Celsius
now we know that temperature is 36 degree Celsius
so from above formula we have
so here the speed will be 352.6 m/s at given temperature T = 36 degree Celsius
