1.	Two Carnot engines ′A′ and ′B′ are operated in succession. The first one, A receives heat from a source at T1=800 K and rejects to a sink at T2 K . The second engine B receives heat rejected by the first engine and rejects it to the another sink at T3=300 K. If the work outputs of the two engines are equal, then the value of T2 is
Answer» Two Carnot engines $^{'} A^{'}$ and $^{'} B^{'}$ are operated in succession. The first one, $A$ receives heat from a source at $T_{1} = 800 K$ and rejects to a sink at $T_{2} K$ . The second engine $B$ receives heat rejected by the first engine and rejects it to the another sink at $T_{3} = 300 K$ . If the work outputs of the two engines are equal, then the value of $T_{2}$ 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
Anair-cored solenoid with length 30 cm, area of cross-section 25 cm2and number of turns 500, carries a current of 2.5 A. The current issuddenly switched off in a brief time of 10−3s. How much is the average back emf induced across the ends of theopen switch in the circuit? Ignore the variation in magnetic fieldnear the ends of the solenoid.
