1.	Two identical beakers A and B contain equal volumes of two different liquids at 60∘C each and left to cool down. Liquid in A has density of 8×102 kg/m3 and specific heat of 2000 J kg−1K−1 while liquid in B has density of 103 kg m−3 and specific heat of 4000 J kg−1K−1. Which of the following best describes their temperature versus time graph schematically? (assume the emissivity of both the beakers to be the same?
Answer» Two identical beakers $A$ and $B$ contain equal volumes of two different liquids at $60^{\circ} C$ each and left to cool down. Liquid in $A$ has density of $8 \times 10^{2} k g / m^{3}$ and specific heat of $2000 J k g^{- 1} K^{- 1}$ while liquid in $B$ has density of $10^{3} k g m^{- 3}$ and specific heat of $4000 J k g^{- 1} K^{- 1}$ . Which of the following best describes their temperature versus time graph schematically? (assume the emissivity of both the beakers to be the same?

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
