A fire truck with sirens on, is driving north on a street. A car is driving south on the same street and sees the fire truck ahead. The car is moving at a speed of 15.7 m/s and the fire truck is moving at a speed of 31.8 m/s. The siren of the fire truck produces a 965 Hz sound. The speed of sound in air is 343 m/s. What frequency does the person in the car hear? If the...

A motorcyclist is moving 24.5 m/s towards a stationary siren, and hears a 894 Hz sound. What is the frequency of the siren when the cyclist is stationary? A motorcyclist is moving 24.5 m/s toward a stationary siren, and hears an 894 Hz sound. What is the frequency of the siren when the cyclist is stationary? (Hint: 894 Hz is the Doppler-shifted frequency.) (Speed of sound 343 m/s) (Unit Hz) nter
The siren of a fire truck at rest emits at a predominant frequency of 1950 Hz. What frequency will you hear if you are at rest and the fire truck car moves at 20.5 m/s (a) toward you? The temperature of that day is 20°C so use Vsound 343 m/s. Please submit your answer with the correct number of significant figures and the corresponding units
