Air contained within a piston-cylinder assembly undergoes three processes in series: A) Process 1-2: compression at constant pre

ssure from P1=10lbf/in2, V1=4ft3 to state 2. B) Process 2-3:Consant volume heating to state 3, where P3=50lbf/in2. C) Process 3-1: Expansion to the initial state, during which the pressure-volume relationship is PV=constant. Sketch the process in series on P-V coordinates. Evaluate the (A) volume at state 2, in ft3, (B) work for each process, in Btu

sergejj [24]

Answer:

  (y^2)/4 square meters

Step-by-step explanation:

For a perimeter length of x, the side of a square will be x/4 and its area will be (x/4)^2.

If one side of the square is shortened by y/2 and the adjacent side is lengthened by y/2, then the difference in side lengths will be y. The area of the resulting rectangle will be ...

  (x/4 -y/2)(x/4 +y/2) = (x/4)^2 -(y/2)^2

That is, the difference in area between the square and the rectangle is ...

  (x/4)^2 - ((x/4)^2 -(y/2)^2) = (y/2)^2 = y^2/4

The positive difference between the area of the square region and the area of the rectangular region is y^2/4 square meters.

ella [17]

Answer:

Not a function

Since x= produces y- -1 and y=-4, the relation (3,-1),(2,5),(4,-6),(3,4),(5,-8) is not a function.
