Choices 'B'; and 'D' both begin with the correct words.
But they should end with the equation
R = V / I
The correct answer is
C ). A hypothesis includes an explanation for why two variables affect each other, but a law only describes how they affect each other.
Answer:
The COP of the system is = 4.6
Explanation:
Given data
Higher pressure = 1.8 M pa
Lower pressure = 0.12 M pa
Now we have to find out high & ow temperatures at these pressure limits.
Higher temperature corresponding to pressure 1.8 M pa
°c = 335.9 K
Lower temperature corresponding to pressure 0.2 M pa
°c = 262.9 K
COP of the system is given by


COP = 4.6
Therefore the COP of the system is = 4.6
