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....
2. Consider the case where you hear the police siren at a frequency of 800 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?
3. If the police car is moving at 34 m/s and you hear a frequency of 550 Hz. when the car is approaching, what is the original frequency of the police car? (use the speed of sound as 343 m/s)
4. If the police car is moving at 34 m/s and you hear a frequency of 450 Hz. when the car has passed you, what is the original frequency of the police car? (use the speed of sound as 343 m/s).
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
Standing at a crosswalk, you hear a frequency of 520 Hz from the siren of an approaching ambulance. After the ambulance passes, the observed frequency of the siren is 430 Hz. Determine the ambulance's speed from these observations. (Take the speed of sound to be 343 m/s.) m/s
Standing at a crosswalk, you hear a frequency of 540 Hz from the siren of an approaching ambulance. After the ambulance passes, the observed frequency of the siren is 431 Hz. Determine the ambulance's speed from these observations. (Take the speed of sound to be 343 m/s.)
You are driving at a velocity of 95 MPH (42.5 m/s) when you hear a police siren behind you. From your previous run-ins with the law, you know that at a particular point in the sound, the police sirens on the police cars in your town emit a frequency of 751.255 Hz. You hear the sound at a frequency of 752.551 Hz. How fast the the police car going (in m/s)? (Assume that the speed of sound is 343 m/s.)
Standing at a crosswalk, you hear a frequency of 510 Hz from the siren of an approaching ambulance. After the ambulance passes, the observed frequency of the siren is 433 Hz. Determine the ambulance's speed from these observations. (Take the speed of sound to be 343 m/s.)
