Chapter 15, Problem 5CQ

A wave pulse travels along a string at a speed of 200 cm/s. What will be the speed if:

a. The string’s tension is doubled?

b. The string’s mass is quadrupled (but its length is unchanged)?

c. The string’s length is quadrupled (but its mass is unchanged)?

d. The string’s mass and length are both quadrupled?

Note that parts a—d are independent and refer to changes made to the original string.
