Explanation:
Did you get the answer? I believe it’s either C. +q or D. 0
Answer:
0.5747 or 57.4%
Explanation:
Your question is not complete so i will assume the right question goes thus;
A Carnot engine extracts 529 J of heat from a high-temperature reservoir during each cycle, and rejects 225 J of heat to a low-temperature reservoir during the same cycle. What is the efficiency of the engine?
Efficiency of a Carnot engine is given by [(Th-Tc) / Th]
using the formula above, the resulting equation will give us; (529-225)/529
=0.574669
Answer:
The Correct Answer is Heat of Combustion
Explanation:
W=force × displacement
5400=270× displacement
20meters=displacement
