A rectangular block is $5 cm × 5 cm × 10cm$ in size. The block is floating in water with $ 5 cm $ side vertical. If it floats with $10 cm $ side vertical, what change will occur in the level of water?
A
No change
B
It will rise
C
It will fall
D
It may rise or fall depending on the density of block

A
No change
a (a)Since no change in volume of displaced water takes place, hence level of water remains same.

A tube is bent into $L$ shape and kept in a vertical plane. If these three liquids are kept in equilibrium by the piston of area $A$ , the value of $\frac {F}{A}$ is
Figure here shows the vertical cross section of a vessel filled with a liquid of density $\rho$. The normal thrust per unit area on the walls of the vessel at the point $P$, as shown, will be
Water from a tap emerges vertically downwards with an initial speed of $1.0\,ms^{-1}.$ The cross-sectional area of the tap is $10^{-4}\,m^2.$ Assume that the pressure is constant throughout the stream of water and that flow is streamlined. The cross-sectional area of the stream, $0.15\,m$ below the tap would be: (take $g = 10\,ms^{-2}$ )
There is a hole of area $A$ at the bottom of cylindrical vessel. Water is filled up to a height $ h$ and water flows out in $ t $ second. If water is filled to a height $4h,$ it will flow out in time equal to
