Answer:
Option D. 0.568 s
Given:
Length of the rope, l = 10.4 m
mass of the rope, M = 2.31 kg
Tension, T = 74.4 N
Solution:
The velocity of the wave, is given as:
Putting the values in the above formula:
Time taken, t can be calculated as:
Since distance between two end is the length of the rope
Therefore, using the formula for time, t:
t = 0.568 s
therefore, time taken for the disturbance to travel from one end to the other is t = 0.568 s
It can contain up to seven
