Answer:410 Hz
Explanation:
It is given that frequency of tuning fork is 415 Hz and hears a beat of 5 beat per second
so untuned frequency must be either 410 Hz or 420 Hz because beat frequency is the difference in frequency of two notes.
When she tightens the string the beat frequency decrease
and velocity
where
where T=tension
it T increase v also increases and from 1 st equation frequency is also increasing therefore untuned frequency must be 410 Hz because beat frequency is decreasing.
Answer:
0.8067 m
69.696 N
Explanation:
m = Mode = 3
M = Mass of string = 4 g
f = Frequency = 180 Hz
l = Length of string = 121 cm
Length of the string is given by
The wavelength is 0.8067 m
Linear density is given by
Speed of the wave
Speed of wave is given by
Tension is given by 69.696 N
