Answer:
Explanation:
Heat engine is device operating in a continuous cycle between two reservoirs such that it transfers heat from a high temperature reservoir to a low temperature reservoir giving some work output in synchronization to Kelvin-Plank statement of the second law of thermodynamics.
<u>Given that:</u>
- temperature of higher temperature reservoir,
- temperature of lower temperature reservoir,
<u>For maximum efficiency:</u>
were:
are the temperatures of higher temperature reservoir and lower temperature reservoir respectively.
I will tell the Chief about the high worth of the Gold and the various
substances it can be used to produce.

Answer:
L= 0.4 kgm²/s
Explanation:
The angular momentum of a hallow spinning sphere is
L = Iω
L = (0.02kgm²) × (20rad/s)
L= 0.4kgm²/s
