SUMMARY
The discussion centers on solving for Qh in the equation η = 1 - (Qc/Qh). Given η = 0.27 and Qc = 9519 J, the correct formula to isolate Qh is Qh = Qc / (1 - η). Substituting the values, Qh calculates to 13039 J, confirming the output from the graphics calculator. This equation is fundamental in thermodynamics, particularly in analyzing heat engines.
