A wave pulse travels along a string at a speed of 220 cm/s . Note that parts a - d are independent and refer to changes made to the original string. All answers should be in cm/s.

a)What will be the speed if the string's tension is doubled?

b)What will be the speed if the string's mass is quadrupled (but its length is unchanged)?

c)What will be the speed if the string's length is quadrupled (but its mass is unchanged)?

d)What will be the speed if the string's mass and length are both quadrupled?

    A wave pulse travels down a slinky. The mass of the slinky is m = 0.94 kg and is initially stretched to a length L = 7.4 m. The wave pulse has an amplitude of A = 0.23 m and takes t = 0.412 s to travel down the stretched length of the slinky. The frequency of the wave pulse is f = 0.45 Hz. 3)What is the average speed of a piece of the slinky as a complete wave...
