1 beat per 5 second will be heard.
Solution:
The two tuning forks sounded together with their respective frequencies produce the following number of beats –
Given: Frequency = 250 Hz
Frequency = 255 Hz
As the beat frequency is difference in frequency of waves, the formula is given by
Beat frequency = = 255 -250 = 5 Hz
Number of beats in 5 sec =
Number of beats =
Number of beat = 1

Answer:
Beat frequency=It is the number of beats produced per second.
It is numerically equal to the difference between the frequencies of the superimposing waves
So beat produced in one second =255-250=5hz
beat produced in 5 second =5×5 =25hz
