A person, with his ear to the ground, sees a huge stone strike the concrete pavement. A moment later two sounds are heard from the impact: one travels in the air and the other in the concrete, and they are 0.65 s apart. The speed of sound in air is 343 m/s, and in concrete is 3000 m/s. Part A How far away did the impact occur? Express your answer to two significant figures and include the appropriate units. MÅ...

Two identical strings on different cellos are tuned to the 420-hertz A note. The peg holding one of the strings slips, so its tension is decreased by 1.5%. What is the beat frequency heard when the strings are then played together?

Two identical strings on different cellos are tuned to the 400-hertz A note. The peg holding one of the strings slips, so its tension is decreased by 1.7%. What is the beat frequency heard when the strings are then played together?

The G string on a violin has a fundamental frequency of 196 Hz. It is 30.0 cm long. While this string is sounding, a nearby violinist effectively shortens (by sliding her finger down the string) the G string on her violin until a beat frequency of 4.7 Hz is heard between the strings on the two violins. When this occurs, how far (cm) down the string did she slide her finger? Assume that the velocity of waves on the violin...

Example 18.7 The Mistuned Piano Strings Two identical piano strings of length 0.775 m are each tuned exactly to 400 Hz. The tension in one of the strings is then increased by 1.0%. If they are now struck, what is the beat frequency between the fundamentals of the two strings? SOLVE IT Conceptualize As the tension in one of the strings is changed, its fundamental frequency changes. Therefore, when both strings are played, they will have different frequencies and beats...

The G string on a violin has a fundamental frequency of 196 Hz. It is 31.0 cm long and has a mass of 0.500 g. While this string is sounding, a nearby violinist effectively shortens the G string on her identical violin (by sliding her finger down the sting) until a beat frequency of 4.00 Hz is heard between the two strings. When that occurs, what is the effective length of her string? ___cm (please write solution legibly)

A piano tuner sounds two strings simultaneously. One has been previously tuned to vibrate at 293.0 ??. The tuner hears 3.0 beats per second. The tuner increases the tension on the as-yet untuned string, and now when they are played together the beat frequency is 1.0 beat per second. (a) What was the original frequency of the untuned string? (b) What is the frequency of the unturned string corresponding to 1.0 beat per second? (c) By what percentage did the...

Two strings are adjusted to vibrate at exactly 280 Hz . Then the tension in one string is increased slightly. Afterward, three beats per second are heard when the strings vibrate at the same time. Figure of 0 Part A Part complete What is the new frequency of the string that was tightened? Express your answer with the appropriate units.
In certain ranges of a piano keyboard, more than one string is tuned to the same...
In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency. If one string slips from its normal tension of 610 N to 530 N, what beat frequency is heard when the hammer strikes the two strings simultaneously? beats/s

A violin string vibrates at 294 Hz when unfingered. At what frequency will it vibrate if it is fingered one-third of the way down from the end? (That is, only two-thirds of the string vibrates as a standing wave.)
