# Efficiency and Temperature in Heat Engine Cycles: Approaching Parts B, C, and D

• singularcell
In summary, the conversation was about the importance of setting achievable goals and having a plan to reach them. The speaker emphasized the need to break down larger goals into smaller, manageable tasks and to stay focused and disciplined in order to achieve success. They also discussed the value of celebrating small victories along the way and adjusting goals as needed.

Homework Statement
Need help with b,c,d.
Relevant Equations
Wnet/QH
e-carnot = 1-(Tc/Th)

I didn't have much trouble with part a but I'm struggling with b,c, and d. I considered the efficiency formula for a heat engine e = work done by engine/ qh
but i am unsure of how to approach it.
for part c) not sure how i can get to Tc without knowing Th
for d) my gut is telling me 5/2 but i have no explanation for that. Any guidance/help is appreciated

Let's see what you've done so far in part (b).
