142688 A liquid $X$ of density $3.36 \mathrm{~g} / \mathrm{cm}^{3}$ is poured in a U-tube in right arm with height $10 \mathrm{~cm}$, which contains Hg. Another liquid $Y$ is poured in left arm with height $8 \mathrm{~cm}$. Upper levels of $X$ and $Y$ are same. What is the density of $Y$ ?

142689 An air bubble of radius $1 \mathrm{~cm}$ rises from the bottom portion through a liquid of density 1.5 $\mathrm{g} / \mathrm{cc}$ at a constant speed of $0.25 \mathrm{~cm} \mathrm{~s}^{-1}$. If the density of air is neglected, the coefficient of viscosity of the liquid is approximately, (in Pas)

142691 An adulterated sample of milk has a density of $1032 \mathrm{~kg}-\mathrm{m}^{-3}$, while pure milk has a density of $1080 \mathrm{~kg}-\mathrm{m}^{-3}$. The volume of pure milk in a sample of $10 \mathrm{~L}$ of adulterer milk is :

142693 Assertion: Machine parts are jammed in winter.
Reason: The viscosity of lubricant used in machine parts increase at low temperature.
