192- In the figure, a transverse wave on a string propagates at speed $20\,\dfrac{\text{m}}{\text{s}}$. If particle M completes 10 full oscillations per second, how many seconds does it take for the wave to travel distance $d$ along the x-axis? [Figure: A transverse wave shown on x-y axes, with amplitude A, point M on the crest, point N in the trough, and distance d marked along x-axis. The wave shows amplitude $A$, $\dfrac{A}{2}$, and $-\dfrac{A}{2}$ marked on y-axis.]
