Vedclass · Answer

(A) The graph shows a hysteresis loop for a rubber band. $1.$ Statement $I$ is incorrect because the graph only shows extension under a tensile force,not compression. $2.$ Statement $II$ is incorrect because the graph starts and ends at the origin $(0,0)$,indicating that the rubber band returns to its original length after the force is removed. $3.$ Statement $III$ is correct. The area enclosed by the hysteresis loop represents the energy dissipated as heat during one complete cycle of stretching and unstretching. Therefore,the rubber band will get heated.
