Design the pc and mar registers using jk flip flops for pc and d flip/flops for mar. each register must be capable of storing three bits. to move the content of pc to mar and increment the pc, two clock ticks are necessary. indicate what register receives the first clock tick and which one receives the second one

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
