A train station bell gives off a fundamental tone of 500 Hz as the train approaches the station at a speed of 30.0 m/s. If the speed of sound in air is 339 m/s, what will be the apparent frequency of the bell to an observer riding the train?

A train travelling at 43.4 m/s is approaching a stationary observer, and sounding a warning horn at 448 Hz. If the speed of sound is 340.7 m/s, calculate the frequency which the observer hears, in Hz to 3 sf.

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
16.4, the wavelength of the train whistle tone reaching the
switchman, in SI units, is given by:
A) 0.32
B) 0.34
C) 0.30
D) 0.36
E) 0.38

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...

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.

A car is parked 20.0 m directly south of a railroad crossing. A train is approaching the crossing from the west, headed directly east at a speed of 55.5 m/s. The train sounds a short blast of its 312-Hz horn when it reaches a point 20.0 m west of the crossing. What frequency does the car's driver hear when the horn blast reaches the car? The speed of sound in air is 343 m/s. (Hint: Assume that only the component...

A train: A enters a train station with constant speed of .00 m/s while another train B leaves the train station with constant speed of 4.00 m/s. At a moment they are both at the same distance of 1 km from the train station they whistle two identical sounds of 400. Hz with acoustic power of 70.0 W each. A passenger standing on the station platform. No wind is blowing. (a) What is the frequency of the sound from A...

A railroad train is traveling at 28.0 m/s in still air. The frequency of the note emitted by the train whistle is 256 Hz . The speed of sound is 344 m/s. A) What frequency is heard by a passenger on a train moving in the opposite direction to the first at 18.0 m/sm/s and approaching the first? B) What frequency is heard by a passenger on a train moving in the opposite direction to the first at 18.0 m/sm/s...
