A Carnot engine operates between two thermal reservoirs at 385∘C and 125∘C, releasing 8.50 kJ per cycle at the lower temperature. i) Sketch the engine cycle on a p−V diagram ii) Label the diagram to show the different processes that occur in a Carnot cycle and show the work done. iii) What is the efficiency of the engine? iv) How much work per cycle is this engine capable of performing? (b) [5 marks] Two charges +q=1.2nC and −q=−1.2nC are separated by a distance d=15μm. i) Calculate the force on an electron at a position in the centre of the pair of charges. ii) Sketch the electric field lines around the pair of charges.
