c (c) From Pascal's principie which was stated in $1652$ by Biaise Pascal, according to which a change in pressure applied to an enclosed incompressible fluid is transmitted undiminshed to every portion of the fluid and uo the walls of its container. This pressure change is independent of height. Hence, on biowing air through a closed pipe containing liquid, pressure will increase in all directions.

Water is moving with a speed of $5.0\,m/s$ through a pipe of cross sectional area $4.0\,cm^2$ . The water gradually descends $10\,m$ as the pipe increase in area to $8.0\,cm^2$ . If the pressure at the upper level is $1.5 \times 10^5\,Pa$ , the pressure at lower level will be
An $L-$ shaped glass tube is just immersed in flowing water towards tube as shown. If speed of water current is $V,$ then the height $h$ upto which water rises will be
In a hydraulic jack as shown, mass of the car $W=800 \,kg , A_1=10 \,cm ^2, A_2=10 \,m ^2$. The minimum force $F$ required to lift the car is $........... N$
Acontainer of large surface area is filled with liquid of density $\rho$ .Acubical block of side edge $a$ and mass $M$ is floating in it with four-fifth of its volume submerged. If a coin of mass $m$ is placed gently on the top surface of the block is just submerged. $M$ is
An air bubble of $1\, cm$ radius is rising at a steady rate of $2.00\, mm/sec$ through a liquid of density $1.5\, gm$ per $cm^3$. Neglect density of air. If $g$ is $1000\, cm/sec^2$, then the coefficient of viscosity of the liquid is
The top of a water tank is open to air and its water level is maintained. It is giving out $0.74\,m^3$ water per minute through a circular opening of $2\,cm$ radius in its wall. The depth of the centre of the opening from the level of water in the tank is close to........ $m$
A thin vertical uniform wooden rod is pivoted at the top and immersed in water as shown. The container is slowly raised. At a certain moment, the equilibrium becomes unstable. If density of water is $9/5$ times the density of wood, then ratio of total length of rod to the submerged length of rod, at that moment is
A body of density $\rho$ is dropped from rest from a height $h$ into a lake of density $\sigma$, where $\sigma > \rho$. Neglecting all dissipative forces, the maximum depth to which the body sinks before returning to float on surface ..........
Water is flowing continuously from a tap having an internal diameter $8 \times 10^{-3}\ m $ The water velocity as it leaves the tap is $0.4$ $ms^{-1}$ છે. The diameter of the water stream at a distance $2 \times 10^{-1}$ $m$ below the tap is close to .......$\times 10^{-3}\;m$
