Question: A rope of mass 0.65 kg is stretched between two supports that are 30 m apart. If the tension in the rope is 120 N, how long will it take a pulse to travel from one support to the other? I am having trouble understanding this above question. Can you please explain this in a simple, non-confusing way.
The force stretching the D string on a guitar is 150N. The string's linear mass density is 0.005 kg/m. What is the speed of the waves on the string?
At an open-air concert a person sits at a location that is 7m and 9.10m, respectively, from speakers at each side of the stage. A musician plays a single 494 Hz tone, explain what the listener hears. Assume the speed of sound is to be 346ms-1.
A 1500-Hz sound and a 8500-Hz sound each emerge from a loudspeaker through a circular opening whose diameter is 0.30 m. Assuming that the speed of sound in air is 343 m/s, find the diffraction angle θ for each sound
The range of human hearing is roughly from twenty Hz to twenty kilohertz. Based on these limits and a value of 343 m/s for the speed of sound, what are the lengths of the longest and shortest pipes (open at both ends and producing sound at their fundamental frequencies) that you expect to find in a pipe organ?
When a guitar string is sounded along with a 440 Hz tuning fork, a beat frequency of 5Hz is heard. When the same string is sounded along with a 436 Hz tuning fork, the beat frequency is 9 Hz. What is the frequency of the string?
A sonar unit on a submarine sends out a pulse of sound into seawater. The pulse returns 1.30 seconds later. What is the distance to the object that reflects the pulse back to the submarine?
(a) When sound emerges from a loudspeaker, is the diffraction angle determined by the wavelength, the diameter of the speaker, or a combination of these two factors? (b) How is the wavelength of a sound related to its frequency ? Explain your answers. The following two lists give diameters and sound frequencies for three
A person stands between two speakers driven by the same source. Each speaker produces a tone with a frequency of 200 Hz on a day when the speed of sound is 330 m/s. The person is 1.65 m from one speaker and 4.95 m from the other. What type of interference does the person sense? a: constructive b: destructive c
An untethered(free) weather balloon travelling with the wind (at wind speed) emits a 1 khz sound wave. The wind is blowing with respect to the land due east at .25 times the speed of sound in air. If the free balloon is moving away (due east)from a tower at same height, what is the frequency of the sound detected at the tower?
