QUESTION:

Alveoli are the tiny sacs of air in the lungs (see Problem 5.136) whose average diameter is \(5.3 \times 10^{-5}~ \mathrm m\) . Consider an oxygen molecule \((5.3 \times 10^{−26} ~\mathrm{kg})\) trapped within a sac. Calculate the uncertainty in the velocity of the oxygen molecule. (Hint: The maximum uncertainty in the position of the molecule is given by the diameter of the sac.)
