Question

In the figure below is shown a snapshot of a pulse on a taut string moving to the right. To the right of the pulse is a small bead fixed in place on the string. For each of the following quantities, select the letter of the graph below that could provide a correct graph of the quantity for the bead in the situation shown (if the vertical axis were assigned the proper units). Note that all the graphs have time on the horizontal axis. If none of the graphs could work, select N. a. The vertical (up-down) displacement of the bead: ---Select-- A) b. The vertical velocity of the bead: ---Select--- 4 C. The horizontal (left-right) displacement of the bead: ---Select--- A d. The horizontal velocity of the bead: [ ---Select---

Explanation / Answer

a) B

b) E

c) C

Because, the bead displacement in x-direction is always zero.

d) C

As there is no displacement in x-direction horizontal component of velocity must be zero.
