Answer» A highly conducting solid sphere of radius $R$ , density $ρ$ and specific heat $s$ is kept in an evacuated chamber. A parallel beam of thermal radiation of intensity $I$ is incident on its surface. Consider the sphere to be a perfectly black body and its temperature at certain instant $t = 0$ is considered as $T_{0}$ [Take Stefan's constant as $σ$ ] The maximum attainable temperature of the sphere is

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. If the displacement current through this surface as a function of time is given as:id=EnRe−tdε0ARWhere, ε0 is the permittivity of free space.The value of n is :
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
