The figure shows a U-tube having a 5 mm × 5 mm square cross-section filled with mercury (specific gravity=13.6) up to a height of 20 cm in each limb (open to the atmosphere).
If $ 5\;cm^3 $ of water is added to the right limb, the new height (in cm, up to two decimal places) of mercury in LEFT limb will be _____________
Group I contains the types of fluids while Group II contains the shear stress - rate of shear relationship of different types of fluids, as shown in the figure.
The correct match between Group I and Group II is
The dimension for kinematic viscosity is
Three rigid buckets, shown as in the figures (1), (2) and (3), are of identical heights and base areas. Further, assume that each of these buckets have negligible mass and are full of water. The weights of water in these buckets are denoted as W_{1}, W_{2}, and W_{3} respectively. Also, let the force of water on the base of the bucket be denoted as F_{1}, F_{2}, and F_{3} respectively. The option giving an accurate description of the system physics is
