Alveoli are tiny sacs in the lungs whose average diamter is `5xx10^(-5)m`. Consider an oxygen molecule `(5.3xx10^(-26)kg)` trapped within a sac. Calculate uncertainty in the velocity of oxygen molecule.

Text Solution

Verified by Experts

Uncertainty in position `Deltax=` Diameter of Alveoli
`=5xx10^(-10)m`
`Deltax Deltav ge(h)/(4pim)`
`Deltavge(6.626xx10^(-34))/(4xx3.14xx5.3xx10^(-26)xx5xx10^(-10))`
`Deltav~~1.99m//sec`.
