select the correct answer. if the tension in a rope is increased, what will happen to the speed of a wave traveling through the rope? a. the speed will increase. b. the speed will decrease. c. the speed will fall to zero. d. the speed will not change.
Answer
Brief Explanations:
The speed of a wave on a string is given by the formula $v = \sqrt{\frac{T}{\mu}}$, where $T$ is the tension and $\mu$ is the linear - mass density. When the tension $T$ increases (assuming $\mu$ remains constant), the value of $\sqrt{\frac{T}{\mu}}$ increases, so the wave speed increases.
Answer:
A. The speed will increase.
