Water rises to a height of 10 cm in a capillary tube and mercury falls to a depth of √2 cm in the same capillary tube. If the density of mercury is ≈14 g/cm3 and angle of contact is 135∘, the ratio of surface tension for water and mercury is (Angle of contact for water and glass is 0∘).

Water rises to a height of 10 cm in a capillary tube and mercury falls

1.	Water rises to a height of 10 cm in a capillary tube and mercury falls to a depth of √2 cm in the same capillary tube. If the density of mercury is ≈14 g/cm3 and angle of contact is 135∘, the ratio of surface tension for water and mercury is (Angle of contact for water and glass is 0∘).
Answer» Water rises to a height of $10 cm$ in a capillary tube and mercury falls to a depth of $\sqrt{2} cm$ in the same capillary tube. If the density of mercury is $\approx 14 {g/cm}^{3}$ and angle of contact is $135^{\circ}$ , the ratio of surface tension for water and mercury is (Angle of contact for water and glass is $0^{\circ}$ ).

A parallel-plate capacitor having plate area A and plate separation d is joined to a battery of emf E and internal resistance R at t=0. Consider a plane surface of area A/2, parallel to the plates and situated symmetrically between them.

A horizontal curve with superelevation e = 0.05 (note, e=tanβ ) has a posted speed limit of 60 km/h. For this speed limit, only those vehicles with Y/X ratio(in figure) greater than 2 and travelling at speeds greater than 1.2 times the speed limit, will overturn. However, with recent increase in truck traffic the speed limit needs to be modified such that only those vehicles with Y/X ratio greater than 3 and travelling at more than 1.2 times the speed limit will overturn. What should be the new speed limit?(in km/hr round off to integer) (with respect to the figure, assume that the vehicle is travelling into the plane of the paper).50
