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 tuner increase the tension on that string to pass from 3 beats per second to one beat per second?
(d) From the position of 1 beat per second, by what percentage has the tuner to increase the tension of unturned string to be tuned exactly at 293.0 ???
( please I want full answer for all question a, b, c and d )

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...

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

While attempting to tune the note C at 131 Hz, a piano tuner hears 5.00 beats/s between a reference oscillator and the string. (a) What are the possible frequencies of the string? (Give the frequencies to the nearest integer.) lower possible frequency Hz higher possible frequency Hz (b) When she tightens the string slightly, she hears 6.00 beats/s. What is the frequency of the string now? (Give the frequency to the nearest integer.) Hz (c) By what percentage should the...

Two piano strings have the same length (0.7 cm) and mass density
(16 grams/meter), but the tension of one string is 6% greater than
the first. If beats with a frequency of 5 Hz are observed when the
third (n=3) harmonics of each string are excited simultaneously,
what is the tension of the string with the lower pitch (frequency)?
Answer in newtons to the nearest newton.
