143097 In a barometer, the mercury level is $76 \mathrm{~cm}$ at sea level. On a hill of height $3 \mathrm{~km}$. If the ratio of density of $\mathrm{Hg}$ to that of air is $10^{4}$, the atmospheric pressure on the hill is

143098 A man is carrying a block of certain material (density $1000 \mathrm{~kg} . \mathrm{m}^{-3}$ ) weighing $1 \mathrm{~kg}$ in his left hand and a bucket full of water, weighing 10 $\mathrm{kg}$, in his right hand. He drops the block in the bucket. How much load does he carry in his right hand now?

143099 The excess pressure inside a spherical soap bubble of radius $1 \mathrm{~cm}$ is balanced by a column of oil (Specific gravity $=0.8$ ), $2 \mathrm{~mm}$ high, the surface tension of the bubble is

143100 When a big drop of water is formed from $n$ small drops of water, the energy loss is 3E, where, $E$ is the energy of the bigger drop. If $R$ is the radius of the bigger drop and $r$ is the radius of the smaller drop, then number of smaller drops $(n)$ is
