To solve this exercise it is necessary to apply the kinematic equations of angular motion.
By definition we know that the displacement when there is constant angular velocity is
From our given data we know that,
Moreover we know that
Therefore for time t=8.1s we have,
That number in revolution is:
Here, we see that there are 15 complete revolutions
And 0.108 revolutions i not complete, so the tunable rotation is
Therefore the angle of the speck at a time 8.1s is
Answer: It will be take 2.6 hours

Answer:
a) The schematic illustrating is attached
b) The heat transfer to the heat engine is 2142.86 kJ, the heat transfer from the heat engine is 1392.86 kJ
c) The heat transfer to the heat engine is 1648.35 kJ, the heat transfer from the heat engine is 898.35 kJ
Explanation:
b) The heat transfer to the engine and the heat transfer from the engine to the air is:
Where
W = 750 kJ
n = 35% = 0.25
Replacing:
c) The efficiency of Carnot engine is:
The heat transfer to the heat engine is:
The heat transfer from the heat engine is:
