Chapter 6, Problem 50QP

Alveoli are tiny sacs of air in the lungs. Their average diameter it $\text{5}\text{.0 }\times {\text{10}}^{\text{-5}}\text{m}$. Calculate the uncertainty in the velocity of an oxygen molecule $\text{(53 }\times {\text{10}}^{\text{-26}}\text{kg)}$ trapped within a sac. (Hint: The maximum uncertainty in the position of the molecule is given by diameter of the sac.)
