A photon of frequency $\nu$ has a momentum associated with it. If $c$ is the velocity of light, the momentum is:

The velocity of a particle is $v=v_0+gt+f{t}^2$. If its position is $x=0$ at $t=0$, then its displacement after unit time ($t=1$) is:

For a given uniform square lamina $ABCD$ with centre $O$, let $I_{AC}$ and $I_{EF}$ be the moments of inertia about the diagonal $AC$ and the line $EF$ passing through $O$ and parallel to side $AB$ respectively. Then:

A point mass oscillates along the $x$ -axis according to the law $x=x_0\cos (\omega t-\pi /4)$. If the acceleration of the particle is written as $a=A\cos (\omega t+\delta )$, then:

Charges $+q,+q,-q,-q$ are placed at the vertices $A,B,C,D$ of a square respectively. Let $\vec{E}$ be the electric field and $V$ the potential at the centre. If the charges on $A$ and $B$ are interchanged with those on $D$ and $C$ respectively, then:
