PLS HELP ME I WILL GIVE BRAINLIEST ONCE I GET THE CORRECT WORKINGS AND ANSWER. "A rope 5m 5 m lon long is is fastened to too hooks 4-0 m apart on a horizontal celling. To the top rope is attached a loka mass so that the segments of the rope are 3.0m and 2.0m Compute the tension in each segment."

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
