Use the following scenario to answer the next question. A rope of length L and linear mass density  is tied to the ceiling on one end. The other end is tied to a spring with spring constant k,and the spring is then attached to the floor,extending it by A.
-The time it takes for a wave pulse to travel from the bottom of the rope to the ceiling is

Quizplus · Accepted Answer

The speed of a wave along a rope is given by the formula v=√(T/μ), where T is the tension in the rope and μ is the linear mass density. In this case, the tension in the rope is equal to the weight of the rope, which is F1gL, where g is the acceleration due to gravity. Thus, v=√(F1gL/μ). The time it takes for a wave pulse to travel from the bottom of the rope to the top is equal to L/v. Substituting the given values, we get:
v=√(F1gL/μ)=√((F1/g)/μ)×g=√(A/μ)×g
L/v=L/(√(A/μ)×g)=L√(μ/A)/g
Therefore, the correct answer is B, which is equal to 11eaa331_f53d_46aa_9fad_1d2e8482beb6_TB6079_11.
