Two eagles fly directly toward one another, the first at 13.5 m/s and the second at 22.5 m/s. Both screech, the first one emitting a frequency of 2950 Hz and the second one emitting a frequency of 3950 Hz. What frequency of sound, in hertz, does the first eagle hear from the second if the speed of sound is 330 m/s?  What frequency of sound, in hertz, does the second eagle hear from the first if the speed of sound is 330 m/s?

Problem 9:  One day when the speed of sound in air is 343 m/s, a fire truck traveling at vs = 34 m/s has a siren which produces a frequency of fs = 438 Hz.Randomized Variables vS = 34 m/sf = 438 Hz       Part (a) What frequency (in Hertz) does the driver of the truck hear?Numeric   : A numeric value is expected and not an expression.fd = __________________________________________Part (b) What frequency (in Hertz) does an observer hear when the truck is moving away?Numeric   : A numeric value is expected and not an expression.fo = __________________________________________   Problem 10:  A student knows that an ambulance siren has a frequency of fs = 395 Hz. He measures, when the ambulance is approaching him, the frequency fo = 416 Hz. Assume the speed of sound is 343 m/s in this problem.       Part (a) Input an expression for the ambulance's speed, vs, in terms of the frequencies and the speed of sound v.Expression   :vs =…

Two eagles fly directly toward one another, the first at 15.0 m/s and the second at 18.7 m/s. Both screech, the first emitting a frequency of 3643 Hz and the other one of 3800 Hz. What frequencies do they receive if the speed of sound is 330 m/s? (Enter your answers to at least the nearest 10 Hz.)

A train is moving at a speed of 50 m/s with its whistle on, the frequency of the whistling sound being 400 Hz. What should be the approximate frequency heard by a stationary observer as the train approaches the observer. Take the speed of sound as 345 m/s when atmospheric temperature is 24°C. 468 Hz 486 Hz 490 Hz 400 Hz

One day when the speed of sound in air is 343 m/s, a fire truck traveling at vs = 25 m/s has a siren which produces a frequency of fs = 424 Hz. vS = 25 m/s f = 424 Hz What frequency (in Hertz) does the driver of the truck hear?  What frequency (in Hertz) does an observer hear when the truck is moving away?

A fire engine siren emits sound at 1260 Hz. The fire engine is driving down the street toward you at 29 m/s. (The speed of sound in air is 343 m/s.) What frequency sound do you hear? What frequency sound do you hear after the fire engine passes you?

Please have answers computer typed.

A passenger on a train approaching a station a 29 m/s hears a bell ringing in the station. Take the speed of sound to be 343 m/s.   the passenger hears a bell at a frequency of 361 Hz. What frequency, in hertz, do the people waiting on the station platform hear?

A bystander hears a siren vary in frequency from 584 Hz to 370 Hz as a fire truck approaches, passes by, and movesaway on a straight street. What is the speed of the truck? (Take the speed of sound in air to be 343 m/s.)

Hassan is driving his truck with a velocity of 18m/s towards a mountain. Kevin who is riding in the truck sounds a horn. The sound reflects from the cliff and is heard by Hassan and Kevin on the truck. What is the change in frequency in hertz if the horn had an initial wavelength of )=0.101 m? The temperature that day was 35 degrees celsius. (Speed of sound = 331+0.6 T(in celsius)). Please give your answer as a whole number.
