Here refrigerator removes 55 kcal heat from freezer
Refrigerator releases 73.5 kcal heat to surrounding
So here we can use energy conservation principle by II Law of thermodynamics
the law says that
here we know that
= heat released to the surrounding
= heat absorbed from freezer
W = work done by the compressor
now using above equation we can write
So here compressor has to do 18.5 k cal work on it
Answer:
The uncertainty in the location that must be tolerated is
Explanation:
From the uncertainty Principle,
Δ Δ
The momentum P = (mass of electron)(speed of electron)
=
=
If the uncertainty is reduced to a 0.0010%, then momentum
=
Thus the uncertainty in the position would be:
Δ
Δ
