A train is moving past a crossing where cars are waiting for it to pass. While waiting, the driver of the lead car becomes sleepy and rests his head on the steering wheel, unintentionally activating the cars horn. A passenger in the back of the train hears the horns sound at a frequency of 428 Hz and a passenger in the front hears it at 402 Hz. Find (a) the trains speed and (b) the horns frequency, assuming the sound travels along the tracks.
A source of sound vibrates with constant frequency. Rank the frequency of sound observed in the following cases from highest to the lowest. If two frequencies are equal, show their equality in your ranking. All the motions mentioned have the same speed, 25 m/s. (a) The source and observer are stationary. (b) The source is moving toward a stationary observer. (c) The source is moving away from a stationary observer. (d) The observer is moving toward a stationary source. (e) The observer is moving away from a stationary source.
Three stationary observers observe the Doppler shift from a source moving at a constant velocity. The observers are stationed as shown below. Rank the observed frequencies for each observer from highest to lowest. A)They observe the same frequencies B)Observer 2, Observer 3, Observer 1 C) Observer 1, Observer 3, Observer 2 D) Observer 1, Observer 2, Observer 3 E) Observer 3, Observer 2, Observer 1
An ambulance passes by a stationary observer releasing its siren at a frequency of 479Hz. The difference between the frequency observed by the observer as the car was approaching and with when the ambulance was moving away was 62Hz. How fast is the ambulance moving? Assume the speed of sound is 339m/s
Is this statement True or False Regardless of who is doing the moving, is the observer and source are getting closer then the observed frequency is higher than the source frequency.
Because of the Doppler effect, the sound heard by an observer listening to a moving ambulance siren, compared to what the observer would have heard if the observer and siren were both at rest... will have a lower pitch if the ambulance siren is moving towards the observer. will have a longer wavelength if the ambulance siren is moving towards the observer. will have a lower frequency if the ambulance siren is moving towards the observer will have a higher frequency if the ambulance siren is moving away from the observer. will have a higher frequency if the ambulance siren is moving towards the observer.
A military jet is flying at an altitude of 8.2 km with a speed of 1.3 Mach. It passes over a stationary observer located on the ground. What will be the distance between the observer and the jet at the moment when the observer hears the sonic boom? Assume that the speed of sound in the air is 343 m/s and does not depend on the altitude.
A train is moving parallel to a highway with a constant speed of 20 m/sec. A car is traveling in the same direction as the train with a speed of 30 m/sec. The car horn sounds at a frequency of 510 Hz, and the train whistle sounds at a frequency of 320 Hz. . A.When the car is behind the train, what frequency does the driver observe for the train whistle? (Treat the train whistleas the sound source, the driver as the listener. B.When the car is in front of the train, what frequency does the passenger on the train observe for the car horn just afterthe car passes? ( Treat the car as the sound source, passenger as the I istener.
An ambulance moves with a speed of magnitude 140 km/h, it moves by sounding its siren with a frequency of 850 Hz. There is an observer moving away from the position of the ambulance with a speed of 25 km/h. (Take the speed of sound to be 340 m/s).Determine the frequency perceived by the observer when the ambulance moves in such a way that it approaches the observer's position.
Use the Doppler equation for a moving source to calculate the observed frequency for a 250.-Hz source of sound if it is moving with a speed of ____ . (Assume that the speed of sound in air is 340. m/s.) 30. m/s towards the observer. 30. m/s away from the observer. 300. m/s towards the observer. 300. m/s away from the observer. 320. m/s towards the observer. 335 m/s towards the observer.
If you consider a blinking light source that is receding an observer, what happens to its frequency?A. Increases B. Decreases C. Remains the same D. Needs more information
A train is moving past a crossing where cars are waiting for it to pass. While waiting, the driver of the lead car becomes sleepy and rests his head on the steering wheel, unintentionally activating the car's horn. A passenger in the back of the train hears the horn's sound at a frequency of 429 Hz and a passenger in the front hears it at 404 Hz. Find the train's speed and the horn's frequency, assuming the sound travels along the tracks. Take the speed of sound to be 343 m/s.
