A radioactive nucleus ${}_Z^{A}X$ undergoes spontaneous decay in the sequence:
$${}_Z^{A}X\stackrel{1}{\to }{}_{Z-1}B\stackrel{2}{\to }{}_{Z-3}C\stackrel{3}{\to }{}_{Z-2}D$$
The possible decay particles in the sequence are:

Polar molecules are the molecules:

The effective resistance of a parallel connection that consists of four wires of equal length, equal area of cross-section and same material is $0.25\Omega$. What will be the effective resistance if they are connected in series?

Column-I gives certain physical terms associated with flow of current through a metallic conductor. Column-II gives some mathematical relations involving electrical quantities. Match Column-I and Column-II with appropriate relations.

The equivalent capacitance of the combination shown in the figure is:
