1.	A solid sphere of radius R, acquires a terminal velocity v1 when falling (due to gravity) through a viscous fluid, having a coefficient of viscosity η. The sphere is broken into 27 identical solid spheres. If each of these spheres acquires a terminal velocity, v2, when falling through the same fluid, the ratio (v1v2) equals:
Answer» A solid sphere of radius $R$ , acquires a terminal velocity $v_{1}$ when falling (due to gravity) through a viscous fluid, having a coefficient of viscosity $η$ . The sphere is broken into $27$ identical solid spheres. If each of these spheres acquires a terminal velocity, $v_{2}$ , when falling through the same fluid, the ratio $(\frac{v_{1}}{v_{2}})$ equals:

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
