The potential energy of a molecule on the surface of a liquid compared to one inside the liquid is

When is growth possible?

$A$ body is executing Simple Harmonic Motion. At a displacement $x$ its potential energy is $E_1$ and at a displacement $y$ its potential energy is $E_2$. The potential energy $E$ at displacement $(x + y)$ is

In $\triangle ABC$, the midpoints of the sides $AB, BC$, and $CA$ are respectively $(l, 0, 0), (0, m, 0)$, and $(0, 0, n)$. Then, $\frac{AB^2+BC^2+CA^2}{l^2+m^2+n^2}$ is equal to

Based on lattice energy and other considerations,which one of the following alkali metal chlorides is expected to have the highest melting point?

In which of the following reactions is hydrogen gas not liberated?
