A guitar produces C by 425 Hz with a string length of 0.350m and a linear density of 1.35g/m. this note is played on a fixed string while the guitarist runs 4.75m/s through the concert hall. Suddenly, a fan starts singing the exact same note as the guitarist approaches her.
*speed of sound is 325m/s

A) at what frequency do the fans hear C
B)At what frequency does the guitarist hear the note the fan is singing
C)By how many decibles does the sound levels change when the fans C arrives with twice the intensity of the guitarist C
D)How many newtons would need to be added or subtragted to the string tension to allow the running guitarist to deliver C at the correct pitch?

On a guitar, the lowest toned string is usually strung to the E note, which produces sound at 82.4 Hz. The diameter of E guitar strings is typically 0.0500 in and the scale length between the bridge and nut (the effective length of the string) is 25.5 in. Various musical acts tune their E strings down to produce a "heavier" sound or to better fit the vocal range of the singer. As a guitarist you want to detune the E...
standing waves on a guitar string
Standing waves on a guitar string form when waves traveling down the string reflect off a point where the string is tied down or pressed against the fingerboard.The entire series of distortions may be superimposed on a single figure, like this (Intro 2 figure) , indicating different moments in time using traces ofdifferent colors or line styles.What is the wavelength λ of the standing wave shown onthe guitar string?

A cellist tunes the C-string of her instrument to a fundamental frequency of 65.4 Hz. The vibrating portion of the string is 0.600 m long and has a mass of 14.5 gA.) With what tension must she stretch that portion of the string?B.) What percentage increase in tension is needed to increase the frequency from 65.4 Hz to 73.4 Hz, corresponding to a rise in pitch from C to D?

I want this code to be written in c++. Take a string of length n as an input from the user such that n>=8 and only lower-case letters (a-z) are allowed as valid string characters. Deleting a letter from the string removes all the occurrences of that letter. The objective is to find the longest possible string such that it is left with only two unique letters and no two consecutive characters in a string are the same. If there...

A guitar player can change the frequency of a string by "bending" it-pushing it along a fret that is perpendicular to its length. This stretches the string, increasing its tension and its frequency. The G string on a guitar is 64 cm long and has a tension of 74 N. The guitarist pushes this string down against a fret located at the center of the string, which gives it a frequency of 392 Hz. He then bends the string, pushing...

The G string on a guitar is 69 cm long and has a fundamental frequency of 196 Hz. A guitarist can play different notes by pushing the string against various frets, which changes the string's length. The third fret from the neck gives B♭ (233.08 Hz); the fourth fret gives B (246.94 Hz). How far apart are the third and fourth frets? Express your answer to two significant figures and include the appropriate units.
