PLEASE SHOW ALL STEPS
A fire truck moving at a speed of 40.0 m/s sounds its siren, which has a frequency of 1250 Hz. It is

passing by a stationary observer in a quiet neighborhood on a day when the temperature is 24.0° C.

A) What is the speed of sound in air on this day?

B) Calculate the frequency of the siren as heard by the stationary observer when the fire truck is approaching the observer.

C) Calculatethefrequencyofthesirenasheardbythestationaryobserverwhenthefiretruckis moving away from the observer.
