OPTION C is the correct answer.
Answer:
no it would not. that is an open circuit and it would need to be closed at the switch for current to flow.
Coefficient of performance or more commonly known as COP is calculated through the equation,
COP = ((T₂)/(T₂ - T₁))
where T₂ is the hot temperature and T₁ is the cold temperature. Similarly, these can also be,
COP = heat ejected / (heat ejected - heat provided)
Substituting,
COP = 22,000 / (22,000 - 15,000) = 3.14
Thus, the value of the COP is approximately 3.14.
