If there are $n$ capacitors, each of capacitance $C$, connected in parallel to a $V \, \text{volt}$ source, then the energy stored is equal to:

In an $LCR$ circuit,the capacitance is changed from $C$ to $2C$. For the resonant frequency to remain unchanged,the inductance should be changed from $L$ to:

Given the standard electrode potentials,
$K^{+} / K = -2.93 \ V$,$Ag^{+} / Ag = 0.80 \ V$
$Hg^{2+} / Hg = 0.79 \ V$
$Mg^{2+} / Mg = -2.37 \ V$,$Cr^{3+} / Cr = -0.74 \ V$
Arrange these metals in their increasing order of reducing power.

If $(p \wedge \sim q) \wedge (p \wedge r) \to \sim p \vee q$ is false,then the truth values of $p, q$ and $r$ are respectively

The oxidation state of $Xe$ in $XeO_3$ and the bond angle in it respectively are:

$2 \pi - \left(\sin ^{-1} \frac{4}{5} + \sin ^{-1} \frac{5}{13} + \sin ^{-1} \frac{16}{65}\right)$ is equal to
