Air contained within a piston–cylinder assembly undergoes three processes in series: Process 1–2: Compression during which the pressure–volume relationship is pV = constant from p1 = 10 lbf/in.2, V1 = 4 ft3 to p2 = 50 lbf/in.2 Process 2–3: Constant volume from state 2 to state 3 where p = 10 lbf/in.2 Process 3–1: Constant pressure expansion to the initial state. Sketch the processes in series on p–V coordinates. Evaluate (a) the volume at state 2, in ft3, and (b) the work for each process, in Btu. 2.26 WP A 0.15-m-d

The solution to this question is attached below:

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.

explanation:

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
