In which activities other than studies should the energy of boys be utilized?

When the temperature of a body increases from $T$ to $T+\Delta T$,its moment of inertia increases from $I$ to $I+\Delta I$. If $\alpha$ is the coefficient of linear expansion of the material of the body,then $\frac{\Delta I}{I}$ is (neglect higher orders of $\alpha$ ).

Genes that are involved in turning on or off the transcription of a set of structural genes are called:

How many stereoisomers are possible for the following molecule?

The maximum number of possible interference maxima for slit-separation equal to twice the wavelength in Young's double-slit experiment is:

$A$ $4 \mu F$ capacitor is charged by a $200 \ V$ battery. It is then disconnected from the supply and connected to another uncharged $2 \mu F$ capacitor. During the process,the loss of energy (in $J$) is:
