The figure shows the graph between stress and strain for a uniform wire at two different temperatures. Then:

Which one of the following is the Young's modulus (in $N/m^2$) for the wire having the stress-strain curve shown in the figure?

The diagram shows the change $x$ in the length of a thin uniform wire caused by the application of force $F$ at two different temperatures $T_1$ and $T_2$. The variations shown suggest that

$A$ student plots a graph from his readings on the determination of Young's modulus of a metal wire but forgets to label the axes. The quantities on $X$ and $Y$ axes may be respectively:

The stress vs. strain curve for the elastic tissue of the aorta,the large tube (vessel) carrying blood from the heart,will be: [Note: Stress is proportional to the square of the strain for the elastic tissue of the aorta.]

The strain-stress curves of three wires of different materials are shown in the figure. $P, Q$ and $R$ are the elastic limits of the wires. The figure shows that
