1.	A Carnot engine with a perfect gas acting as the working substance is operated backwards and is employed to freeze water at 0∘C. The engine is driven by a 200 W electric motor. Find the amount of water frozen per minute. The outside temperature is 20∘C. Specific latent heat of fusion (in g/min) of ice=80 cal/g and 1 J=4.2 cal.
Answer» A Carnot engine with a perfect gas acting as the working substance is operated backwards and is employed to freeze water at $0^{\circ} C$ . The engine is driven by a $200 W$ electric motor. Find the amount of water frozen per minute. The outside temperature is $20^{\circ} C$ . Specific latent heat of fusion (in $g / m i n$ ) of $ice = 80 c a l / g a n d 1 J = 4.2 c a l$ .

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
