Agas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes: process 1-2: compression with pv = constant, from p1 = 1 bar, v1 = 2 m3 to v2 = 0.2 m3 , u2 - u1 = 100 kj. process 2-3: constant volume to p3 = p1. process 3-1: constant-pressure and adiabatic process. there are no significant changes in kinetic or potential energy. determine the net work of the cycle, in kj, and the heat transfer for process 2-3, in kj. is this a power cycle or a refrigeration cycle? explain. (hint: evaluating whether the work is done by or on the system should answer the question of what type of cycle this is.)

Is there a picture to go along with this

The answer is 12, for the points

Ibelieve that the correct answer is: c. along plate boundaries

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
