Infinite number of bodies, each of mass $2\text{kg}$ are situated on the x-axis at distances $1\text{m},2\text{m},4\text{m},8\text{m},\dots$, respectively, from the origin. The resulting gravitational potential due to this system at the origin will be:

The following four wires are made of the same material. Which of these will have the largest extension when the same tension is applied?

The wettability of a surface by a liquid depends primarily on:

The molar specific heats of an ideal gas at constant pressure and volume are denoted by $C_p$ and $C_v$, respectively. If $\gamma =\frac{C_p}{C_v}$ and $R$ is the universal gas constant, then $C_v$ is equal to:

A piece of iron is heated in a flame. It first becomes dull red, then reddish yellow, and finally turns white hot. The correct explanation for this observation is possible using:
