Question

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.

Part A What will be the speed if the string's tension is doubled? Express your answer in centimeters per second.

Part B What will be the speed if the string's mass is quadrupled (but its length is unchanged)? Express your answer in centimeters per second.

Part C What will be the speed if the string's length is quadrupled (but its mass is unchanged)? Express your answer in centimeters per second.

Part D What will be the speed if the string's mass and length are both quadrupled? Express your answer in centimeters per second.

If the mass per unit length of a violin string was quadrupled without changing the string's tension, the speed with which a wave (produced by the player's bowing action) travels on that string would -become four times its former value. -become one half of its former value. -become two times its former value. -become one quarter of its former value. -not change.

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...
