After terminal velocity is reached, the acceleration of a body falling through a fluid is,

The diagram shown below represents the applied forces per unit area with the corresponding change $X$ (per unit length) produced in a thin wire of uniform cross-section in the curve shown. The region in which the wire behaves like a liquid is

The diagram below shows the change in the length $X$ of a thin uniform wire caused by the application of stress $F$ at two different temperatures $T_1$ and $T_2$. The variation shown suggests that

The diagram shows a force-extension graph for a rubber band. Consider the following statements:
I. It will be easier to compress this rubber than expand it.
II. Rubber does not return to its original length after it is stretched.
III. The rubber band will get heated if it is stretched and released.

Which of these can be deduced from the graph:
