Explanation:
Given
Frequency of beats is 3 beats per second
Frequency of first tuning fork is
Beat frequency is difference in the frequency of tuning forks i.e.
either or
so
or
so there is not enough information given to decide.
The time taken by the pulse to travel from one support to the other is 0.208 s.
<h3>Given:</h3>The mass of the cord is m = 0.65 kg.
The distance between the supports is, d = 8.0 m.
The tension in the cord is T = 120 N.
The time taken by the pulse to travel from one support to the other is given as,
Here, v is the linear velocity of a pulse. Its value is,
Then,
Thus, the time taken by the pulse to travel from one support to the other is 0.208 s.
