$A$ body of mass $m$ and radius of gyration $K$ has an angular momentum $L$. Then its angular velocity is

The number of significant figures in $23.023$,$0.0003$,and $2.1 \times 10^{-3}$ are respectively:

Two bodies $A$ and $B$ start from the same point at the same instant and move along a straight line. $A$ moves with uniform acceleration $a$ and $B$ moves with uniform velocity $V$. They meet after time $t$. The value of $t$ is:

If $f: R \rightarrow R$ is an even function having derivatives of all orders,then which of the following is an odd function?

An ideal gas undergoes a quasi-static, reversible process in which its molar heat capacity $C$ remains constant. If during this process the relation of pressure $P$ and volume $V$ is given by $PV^n = \text{constant}$, then $n$ is given by (Here $C_P$ and $C_V$ are molar specific heat at constant pressure and constant volume, respectively).

$A$ gaseous mixture consists of $16 \ g$ of helium and $16 \ g$ of oxygen. The ratio $\frac{C_p}{C_v}$ of the mixture is
