The atmospheric pressure at a place is $10^5 \,Pa$. If tribromomethane (specific gravity $=2.9$ ) be employed as the barometric liquid, the barometric height is .......... $m$
$3.52$
$1.52$
$4.52$
$2.52$
A $U-$ tube containing a liquid moves with a horizontal acceleration a along a direction joining the two vertical limbs. The separation between these limbs is $d$ . The difference in their liquid levels is
Two vessels have the same base area but different shapes. The first vessel takes twice the volume of water that the second vessel requires to fill upto a particular common height. Is the force exerted by the water on the base of the vessel the same in the two cases ? If so, why do the vessels filled with water to that same height give different readings on a weighing scale ?
The height to which a cylindrical vessel be filled with a homogeneous liquid, to make the average force with which the liquid presses the side of the vessel equal to the force exerted by the liquid on the bottom of the vessel, is equal to
Two immiscible liquids $A$ and $B$ are kept in an U-tube. If the density of liquid $A$ is smaller than the density of liquid $B$, then the equilibrium situation is
A nurse measures the blood pressure of a seated patient to be $190 \,mm$ of $Hg$.
