Solve the following Doppler Shift problems. Show your work. 1. A concert goer hurries down the aisle to her seat at a speed of 3 m/s. What frequency does she hear when the note A (440 Hz) is played by an instrument of stage if the speed of sound in the concert hall is 343 m/s? 2. A fire engine with a 600 Hz siren approaches then passes a stationary observer. If the engine is traveling at 20 m/s on...
1 Consider the case where you hear the police siren at a frequency of 800 Hz when approaching and 400 Hz after passing you. How fast is the police traveling? 2. approaching and 450 Hz after passing you, but because of changes in the atmosphere, the speed of sound is 300 m/s. How fast is the police traveling? Consider the case where you hear the police siren at a frequency of 800 Hz when 3. If the police car is...

Please answer all four questions. 1 Consider the case where you hear the police siren at a frequency of 800 Hz when approaching and 400 Hz after passing you. How fast is the police traveling? 2. approaching and 450 Hz after passing you, but because of changes in the atmosphere, the speed of sound is 300 m/s. How fast is the police traveling? Consider the case where you hear the police siren at a frequency of 800 Hz when 3....
Tutorial Sound Waves . A sound source which produces sound of frequency 300 Hz moves along a straight line and passes by a stationary observer. The observer notices that the frequency of sound heard change Speed of sound in air 330 m s-1] 0when the sound is moving away from him. Determine the speed of the sound source. its siren emitting a sound of frequency 600.0 Hz moves with a speed of me that the speed of sound is 345...
2)While standing at a point on the roadside shoulder, a police car chasing a speeder was approaching you at speed V. At that moment you hear the siren of the police car at a frequency of f’=560 Hz. When the police car passes, the frequency of the siren changes to f”=480 Hz. The speed of sound is vs=360 m/s. Express f” in terms of vs, f, and V where f is the frequency of siren produced (symbols only).
Please show all work, I want to understand the process as well. A police car has an 750-Hz siren. It is traveling at 32.0 m/s on a day when the speed of sound through air is 343 m/s. The car approaches and passes an observer who is standing along the roadside. a) What is the frequency from the perspective of the observer when the car is approaching? (2 pts) b) What is the frequency from the perspective of the observer...
You are driving down the highway at 14.9 m/s when you approach an automobile accident on the side of the road. To keep traffic away from it, a stationary police car has its siren going; to the police, the siren has a frequency of 1100 Hz. If the speed of sound in air is 332 m/s, what frequency (in Hz) will be heard by you in your car? If the relative motion in the previous question was reversed (i.e. if...
you are driving along a highway at 35.0 m/s when you hear the siren of a police car approaching you from behind at constant speed and you perceive the frequency as 1310 Hz. you are relieved that he is in pursuit of a different driver when he continues past you, but now you perceive the frequency as 1240 hz. what is the frequency of the siren in the police car? the speed of sound in air is 343 m/s
A motorcyclist is traveling north on a road at a speed of 21.0 m/s. A police car, traveling south at a speed of 33.0 m/s, approaches with its siren producing sound at a frequency of 2550 Hz. (Enter your answers in Hz. Assume that the speed of sound in air is 343 m/s.) (a) What frequency does the motorcyclist observe as the police car approaches? (Enter your answer to the nearest integer.) Hz (b) What frequency does the motorcyclist detect...
