A submarine’s sonar emits a sound with a frequency of 875 Hz. The speed of sound in seawater is about 1500 m/s. If you measure the frequency of the sound to be 870 Hz, what is the velocity of the submarine?
a tuba creates a 4th harmonic of frequency 116.5 hz. when the first valve is pushed, it opens an extra bit of tubing 0.721 m long. what is the new frequency of the 4th harmonic? speed of sound= 343 m/s
How do I solve? A closed pipe creates a fifth harmonic frequency of 125 Hz. What is the next lower frequency that will create a standing wave in the pipe? (Speed of sound 343 m/s) (Unit Hz)
On a day when the speed of sound in air is 345 m/s, the fundamental frequency of an open-ended pipe is 690 Hz. If the second harmonic of this pipe has the same wavelength as the second overtone (third harmonic) of a closed-end pipe, what is the length of each pipe?
a trumpet plays its 3rd harmonic at 510 Hz. it then opens a valve, which adds 0.110 m to its length. what is the new 3rd harmonic frequency?
Tutorial Sound Waves . A sound source which produces sound of frequency 300 Hz moves along a straight line and passes by a stationary observer. The observer notices that the frequency of sound heard change Speed of sound in air 330 m s-1] 0when the sound is moving away from him. Determine the speed of the sound source. its siren emitting a sound of frequency 600.0 Hz moves with a speed of me that the speed of sound is 345...
2 The frequency of the sound heard by the motorcyclist is given by the expression A motorcyclist moves to the right with a speed of 20 m/s. A police car with velocity 30 m/s to the left emits a sound with a frequency of 400 Hz. Speed of sound in air is 340 m/s. 400 Hz 340 - 20 m/s 340 - (-30 m/s) a. (340 - (20 m/s) 400 Hz 340 - 30 m/s b. (340 - (-20 m/s)...
1. A source moving with a speed 37 m/s, emits a sound wave with a frequency f = 377 Hz. Determine the frequency detected by a stationary observer if the speed of sound is v = 343 m/s and the source is moving towards the observer. 2.A stationary source, emits a sound wave with a frequency f = 428 Hz. Determine the frequency detected by an observer moving towards the source with a speed v = 43 m/s, if the...
The siren on an ambulance is emitting a sound whose frequency is 2850 Hz. The speed of sound is 343 m/s. (a) If the ambulance is stationary and you (the "observer") are sitting in a parked car, what are the wavelength and the frequency of the sound you hear? (b) Suppose that the ambulance is moving toward you at a speed of 26.6 m/s. Determine the wavelength and the frequency of the sound you hear. (c) If the ambulance is...
How deep should be ocean to enhance physiologically harmful infrasonic waves of 6 Hz frequency? Take 1.47 km/s for the speed of sound in water and find the minimum and next to minimum depths of the ocean. The minimum depth, h1 = The next to minimum depth, h2 = What is the length of the string if the speed of wave is 255 m/s? The length of the string, L =
