Vedclass · Answer

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