Ship A is traveling 20 m/s due east. Ship B is traveling 15 m/s due west...
As a bat flies toward a wall at a speed of 6.0 m/s, the bat emits an ultrasonic sound wave with frequency 30.0 kHz. What frequency does the bat hear in the reflected wave? Ship A is traveling 20 m/s due east. Ship B is traveling 15 m/s due west away from Ship A. Ship A sounds a horn with a frequency of 1500 Hz. What frequency does an observer on Ship A hear in the reflected wave from Ship...
A car's horn produces a frequency of 440 Hz at rest.If the car is traveling east at 20 m/s towards an observer, what speed and direction (E or W) must an observer have to hear a frequency of 450 Hz?
A trailer truck traveling east at 24.0 m/s sounds a 600 Hz horn. What is the wavelength of the sound heard by a stationary listener located west of the truck? (The speed of sound is 336 m/s)
2. A trailer truck traveling east at 20.0 m/s sounds a 900 Hz horn. What is the wavelength of the sound heard by a stationary listener located west of the truck? (The speed of sound is 338 m/s) meters
A car sounding its horn (rated by the manufacturer at 600 Hz) is moving at 15.0 m/s toward the east. A stationary observer is standing due east of the oncoming car. 1) What frequency will he hear assuming that the speed of sound is 343 m/s? (Express your answer to two significant figures.) 2) What if the observer is standing due west of the car as it drives away? (Express your answer to two significant figures.)
You are driving east at 25.0 m/s as you notice an ambulance traveling west toward you at 35.0 m/s. The sound you detect from the sirens has a frequency of 305 Hz . Part A Is the true frequency of the sirens is greater than 305 Hz , less than 305 Hz , or exactly 305 Hz
You are driving east at 25.0 m/s as you notice an ambulance traveling west toward you at 35.0 m/s. The sound you detect from the sirens has a frequency of 295 Hz . Determine the true frequency of the sirens. Assume normal room temperature.
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...
B) An ambulance travels east down a highway at a speed of 33.5 m/s, and its siren emits a sound frequency at a frequency of 400 Hz. What frequency is heard by a person in a car traveling west at 24.6 m/s: a) as the car approaches the ambulance ? (8 pts) b) as the car moves away from the ambulance ? (7 pts) (Take the speed of sound to be 343 m/s)
A bystander hears a siren vary in frequency from 550 Hz to 364 Hz as a fire truck approaches, passes by, and moves away on a straight street. What is the speed of the truck? (Take the speed of sound in air to be 343 m/s.) m/s b. A trailer truck traveling east at 20.0 m/s sounds a 800 Hz horn. What is the wavelength of the sound heard by a stationary listener located west of the truck? (The speed...
