H C Verma Solutions for Chapter: Some Mechanical Properties of Matter, Exercise 3: OBJECTIVE II

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

The properties of a surface are different from those of the bulk liquid because the surface molecules

The rise of a liquid in a capillary tube depends on

The contact angle between a solid and a liquid is a property of

A liquid is contained in a vertical tube of a semicircular cross-section. The contact angle is zero. The force of surface tension on the curved part and the flat part is in the ratio

When a capillary tube is dipped into a liquid, the liquid neither rises nor falls in the capillary.

A solid sphere moves at a terminal velocity of $20 \mathrm{m} {\mathrm{s}}^{-1}$ in the air at a place where $g=9.8 \mathrm{m} {\mathrm{s}}^{-2}$. The sphere is taken in a gravity-free hall having air at the same pressure and pushed down at a speed of $20 \mathrm{m} {\mathrm{s}}^{-1}$.
