A thermodynamic system is taken from an initial state i with internal energy U

_{i}= 100 J to the final state f along two different paths iaf and ibf, as schematically shown in the figure. The work done by the system along the paths af, ib and bf are W_{af}= 200 J, W_{ib}= 50 J and W_{bf}= 100 J respectively. The heat supplied to the system along the path iaf, ib and bf are Q_{iaf}, Q_{ib}and Q_{bf}respectively. If the internal energy of the system in the state b is U_{b}= 200 J and Q_{iaf}= 500 J, the ratio Q_{bf}/ Q_{ib}isYour input ____

Steel wire of lenght ‘L’ at 40

^{o}C is suspended from the ceiling and then a mass ‘m’ is hung from its free end. The wire is cooled down from 40^{o}C to 30^{o}C to regain its original length ‘L’. The coefficient of linear thermal expansion of the steel is 10^{−5}/^{o}C, Young’s modulus of steel is 10^{11}N/m^{2}and radius of the wire is 1 mm. Assume that L >> diameter of the wire. Then the value of ‘m’ in kg is nearlyYour input ____
