Answer:
(a) 0.525
(b) 1750J
Explanation:
Coefficient of Performance (COP) = Q2/(Q1 - Q2)
Q1 = heat rejected to the surrounding = 1750J
Q2 = heat absorbed in the environment = 585K
COP = 585/(1700 - 585) = 585/1115 = 0.525
(b). Heat expelled to the surrounding (room) = 1750J
Answer:
A compass can detect a magnetic field and show its direction. Iron filings can show the shape of a magnetic field. A gaussmeter can detect a field and indicate its strength.
