If a graph is plotted between 1/v and 1/u , which one of the graph shown in figure is approximately correct ?

The distance v of the real image formed by a convex lens is measured for various object distance u. A graph is poltted between v and u, which one of the following graphs is correct

In the V-T graph shown in figure match the following.

Figure shows the displacement tiime (x-t) graph of a body moving in a straight line which one of the graph shown in figure represents the velocity- time (v-t) graph of the motion of the body.

A graph plotted between log k vs (1)/(T) is represented by

In Arrehenius equation if a graph is plotted between logK and 1/T, the slope of the curve will be:
