A train is moving parallel and adjacent to a highway with a constant speed of 32 m/s.
A train is moving parallel and adjacent to a highway with a constant speed of 32 m/s. A car is traveling in the same direction as the train at 64 m/s. The car's horn sounds at 520 Hz and the train's whistle sounds at 320 Hz. When the car is behind the train what frequency does an occupant of the car observe for the train whistle? The speed of sound is 343 m/s. Answer in units of Hz. When the car is in...

A commuter train passes a passenger platform at a constant speed of 41.7 m/s. The train horn is sounded at its characteristic frequency of 350 Hz. (a) What overall change in frequency is detected by a person on the platform as the train moves from approaching to receding? (Indicate whether the frequency increases of decreases with the sign of your answer.) Hz (b) What wavelength is detected by a person on the platform as the train approaches?

A train is traveling at 30.0 m/s relative to the ground in still air. The frequency of the note emitted by the train whistle is 262 Hz. The speed of sound in air should be taken as 344 m/s. Part AWhat frequency fapproach is heard by a passenger on a train moving at a speed of 18.0 m/s relative to the ground in a direction opposite to the first train and approaching it? Express your answer in hertz. Part B What frequency frecede is heard...
4. In one of the original Doppler experiments, a tuba was played on a train at a speed of 60 km/h, at a constant frequency of 75 Hz, while a second identical tuba played the same note on the plat...
4. In one of the original Doppler experiments, a tuba was played on a train at a speed of 60 km/h, at a constant frequency of 75 Hz, while a second identical tuba played the same note on the platiorm at the railway station. Assume the observer is standing still on the platiorm on a day when the outside air temperature is 20° C a. What is the effect that is observed regardless of any sound from the tuba at...

A train is approaching a signal tower at a
speed of 40 m/s. The train engineer sounds the 1000 Hz whistle and
a switchman in the tower responds by sounding the 1200 Hz siren.
The air is still and the speed of sound is 340 m/s. 9) In Situation

switchman, in SI units, is given by:
A) 0.32
B) 0.34
C) 0.30
D) 0.36
E) 0.38

A TRAIN SOUNDS ITS WHISTLE AS IT APPROACHES AND LEAVES A RAILROAD CROSSING. AN OBSERVER AT THE CROSSING MEASURES A FREQUENCY OF 219 HZ AS THE TRAIN APPROACHES AND A FREQUENCY OF 184 HZ AS THE TRAIN LEAVES. THE SPEED OF SOUND IS 340 M/S. FIND THE SPEED OF THE TRAIN AND THE FREQUENCY OF ITS WHISTLE. . Please provide work shown and show what each variable represents thank you so much.

Doppler Effect You are waiting at a train station when an approaching express train sounds its 400 Hz horn, warning everyone to stand back from the platform as it passes. If you perceive the frequency of the horn to be 425 Hz as the train approaches, how fast must the train be moving towards you? You may assume the speed of sound is 343 m/s.
