A341.3 hz tuning fork is resonating in a closed tube on a cool day. if the tube has a length of 0.24 m, then what is the speed of sound in this experiment? a) 328 m/s b) 340 m/s c) 343 m/s d) there is not enough information to tell.

f = frequency of tuning fork = 341.3 Hz

L = length of the tube in the experiment = 0.24 m

v = speed of the sound used in the experiment = ?

fundamental frequency in closed tube is given as

inserting the values

v = 4 (341.3) (0.24)

v = 327.65

hence the correct choice comes out to be A) 328 m/s

no sign of dia of fuel cell

what is the actual question though?
