At STP $x$ g of a metal hydrogen carbonate (MHCO$_3$) (molar mass $84 \, {g/mol}$) on heating gives CO$_2$, which can completely react with $0.02 \, {moles}$ of MOH (molar mass $40 \, {g/mol}$) to give MHCO$_3$. The value of $x$ is:

In Young's double slit experiment, the intensity at a point where the path difference is $ \frac{\lambda}{6} $ ( $ \lambda $ being the wavelength of the light used) is $ I $. If $ I_0 $ denotes the maximum intensity, $ \frac{I}{I_0} $ is equal to

A → P is a zero-order reaction. At 298 K, the rate constant of the reaction is $ 1 \times 10^{-3} $ mol L$^{-1}$ s$^{-1}$. Initial concentration of 'A' is 0.1 mol L$^{-1}$. What is the concentration of 'A' after 10 sec?

A particle starts from rest and moves in a straight line. It travels a distance $2L$ with uniform acceleration and then moves with a constant velocity a further distance of $L$. Finally, it comes to rest after moving a distance of $3L$ under uniform retardation. Then the ratio of average speed to the maximum speed $ \left( \frac{V_{avg}}{V_{m}} \right) $ of the particle is:
