Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 35.9 m/s and train 2 at a speed of 27.6 m/s. If the engineer of train 1 sounds his horn which has a frequency of 520 Hz, determine the frequency of the sound heard by the engineer of train 2. (Use 343 m/s as the speed of sound. Enter your answer to the nearest Hz.)

Two trains on separate tracks move toward each other. Train 1 has a speed of 141 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? Hz
Two trains on separate tracks move toward each other. Train 1 has a speed of 109 km/h; train 2, a speed of 96.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? Hz
Two trains on separate tracks move toward each other. Train 1 has a speed of 113 km/h; train 2, a speed of 59.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? Hz A person wears a hearing aid that uniformly increases the intensity level of all audible frequencies of sound by 30.7 dB. The hearing aid picks up sound having a frequency of 250 Hz...
.. + -/1 points SerCP10 14.P.025.WI. Two trains on separate tracks move toward each other. Train 1 has a speed of 117 km/h; train 2, a speed of 73.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1?
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...
Two trains are traveling on the same track and in the same direction. The first train, which is behind the second train, blows a horn whose frequency is 266 Hz. The second train detects a frequency of 284 Hz. If the speed of the second train is 13.8 m/s, what is the speed of the first train?
A train is moving pass 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 444 Hz and a passenger in the front hears it at 415 Hz. Find the train's speed and the horn's frequency, assuming the sound travels along...
6)Two adjacent natural frequencies of an organ pipe are determined to be 912 Hz and 1008 Hz. (Assume the speed of sound is 343 m/s.) (a) Calculate the fundamental frequency of this pipe. Answer must be in Hz (b) Calculate the length of this pipe. Answer must be in m 7)A train sounds its horn as it approaches an intersection. The horn can just be heard at a level of 60 dB by an observer 10 km away. (a) What...
Two trains face each other on adjacent tracks. They are initially at rest, and their front ends are 49 m apart. The train on the left accelerates rightward at 0.87 m/s2.
