Answer:
zero
Explanation:
A Carnot engine is an ideal engine in which the process is cyclic and reversible.
A Carnot engine is the engine whose efficiency is 100 % and the entropy in is equal to entropy out. That means the net change in entropy is zero.
The potential energy is 4.10 J
Explanation:
The potential energy of a body is given by

where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object relative to the ground
For the lemming in this problem we have
m = 0.078 kg is its mass
h = 5.36 m is the height above the ground
is the acceleration of gravity
Solving the equation,

If you use the stairs at normal speed, you will survive longer, and go up higher.
When going up the stairs twice as fast, you lose energy more quickly, but height would remain the same.
