Question

The figure below shows a photograph of a pulse moving to the right on a taut string. The red dot to the right of the figure is a small bead of negligible mass attached to the string.

7) The figure below shows a photograph of a pulse moving to the right on a taut string. The red dot to the right of the figure is a small bead of negligible mass attached to the string For each of the following quantities, select the letter of the graph in the figure below that could provide a correct graph of the quantity (if the vertical axis were assigned the proper units) and write it on your answer sheet. If none of the graphs would work, write N (a) The vertical (up-down) displacement of the bead. (b) The vertical velocity of the bead. (c) The horizontal left-right) displacement of the bead. (d) The horizontal velocity of the bead

Explanation / Answer

(a) B........ As initially it's vertical displacement is upward and as the path of pulse first it travel greater slope path

(b) E.......vertical velocity initially is positive and then downward

(c) C...... horizontal displacement is throughout zero.

(d) ....... velocity is same as that of pulse
