A train moving at a speed of 40m/s sounds its whistle, which has a frequency of 500Hz. Determine the frequency heard by a stationary observer as the train approaches the observer. The ambient temperature is 24°C.
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.
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 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 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 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...
Two trains on separate tracks move toward one another. Train 1 has a speed of 110 km/h, train 2 a speed of 85.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? (Assume the speed of sound is 345 m/s.)
QUESTION 6 10 points The frequency of a train whistle is known to be 470 Hz.

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...
