A trucking moving at 25m/s emits a 400-Hz signal. The temperature that day is 40 o C.

a) Determine the speed of sound at 40o C

Determine the frequency and the wavelength experience by a stationary observer, when b) the truck is approaching the observer.

c) the truck is moving away from the observer.

d) the beat frequency if the observer hears the signal from a truck approaching and the signal from a trucking moving away at 25m/s,

e) the average frequency from part (c).
