A cylindrical vessel containing a liquid is rotated about its axis so that the liquid rises at its sides as shown in the figure. The radius of vessel is $5\, cm$ and the angular speed of rotation is $\omega\; rad \,s^{-1}$. The difference in the height, $h($ in $cm )$ of liquid at the centre of vessel and at the side will be
The platelets are drifting with the blood flowing in a streamline flow through a horizontal artery as shown below Artery is contracted in region $II$. Choose the correct statement.
Write Bernoulli’s principle in word.
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
A plane is in level flight at constant speed and each of its two wings has an area of $25 \;m ^{2}$ If the speed of the air is $180 \;km / h$ over the lower wing and $234\; km / h$ over the upper wing surface, determine the plane's mass in $kg$. (Take air density to be $1\; kg m ^{-3}$ ).
