Answer:
a) 90 kJ
b) 230.26 kJ
Explanation:
The pressure at the first point
= 10 bar —> 10 x 102 = 1020 kPa
The volume at the first point
= 0.1 m^3
The pressure at the second point
= 1 bar —> 1 x 102 = 102 kPa
The volume at the second point
= 1 m^3
Process A.
constant volume V = C from point (1) to P = 10 bar.
Constant pressure P = C to the point (2).
Process B.
The relation of the process is PV = C
Required
For process A & B
(a) Sketch the process on P-V coordinates
(b) Evaluate the work W in kJ.
Assumption
Quasi-equilibrium process
Kinetic and potential effect can be ignored.
Solution
For process A.
V=C
There is no change in volume then

The work is defined by

║
V║limit 1--0.1
90 kJ
Process B
PV=C
By substituting with point (1) C = 10^2 x 1= 10^2
The work is defined by

║
ln(V)║limit 1--0.1
=230.26 kJ
What grade your in your in a higher grade than me wish I could help
Answer:
The two poles closest to each other are opposite magnetic poles
Explanation:
Just took the test
Heya!!!
Answer to your question:
C.
Energy transferred to a machine equals energy transferred from it.
Law of conservation of energy states that total energy of an isolated system remains constant
Energy can neither be created nor be destroyed. Machine follows the same rule.
Hope it helps ^_^
The answer to this is that it is FALSE!
