Problem 5: A musician uses a tuning fork of frequency f = 242 Hz to tune his guitar and his trumpet. There is a beat frequency between the tuning fork and the guitar string and between the tuning fork and the trumpet for this note of freat = 3 Hz. Part (a) The musician increases the tension in the guitar string and notices that the beat frequency increases. Choose the correct answer from the options below. MultipleChoice : 1) It is not possible to tune the guitar string. 2) The frequency of the note emitted by the guitar string was originally less than that emitted by the tuning fork. 3) There is not enough information. 4) The frequency of the note emitted by the guitar string was originally equal to that emitted by the tuning fork. 5) The frequency of the note emitted by the guitar string was originally greater than that emitted by the tuning fork. Part (b) Find the original frequency of this note fg in Hz on the guitar string. Numeric : A numeric value is expected and not an expression. fG = 245 Part (c) Determine the ratio T '/T between the tension in the guitar string before tuning T and the tension in the guitar string once it is tuned T' to eliminate the beat frequency. Numeric : Anumeric value is expected and not an expression. T 'IT = Part (d) If the original tension T is 100 N, what must be the new tension T' in Newtons? Numeric : Anumeric value is expected and not an expression. T' = 97.56 Part (e) The musician increases the length of an air column in the trumpet and notices that the beat frequency increases. Choose the correct answer from the options below. MultipleChoice : 1) It is not possible to tune the trumpet. 2) The frequency of the note emitted by the trumpet was originally greater than that emitted by the tuning fork. 3) There is not enough information. 4) The frequency of the note emitted by the trumpet was originally-equal to that emitted by the tuning fork. 5) The frequency of the note emitted by the trumpet was originally less than that emitted by the tuning fork. Part (f) Find the original frequency of this note fr in Hz from the trumpet. Numeric : A numeric value is expected and not an expression. fr = Part (g) Determine the ratio L' |L between the length of the air column before tuning L and the length of the column once it is tuned L' to eliminate the beat frequency. Numeric : A numeric value is expected and not an expression. L'IL = Part (h) If the original length L is 150 cm, what must be the new length L' in m? Numeric : A numeric value is expected and not an expression. L'=
