i don't know how to do this...nothing comes to mind. any help will be appreciated!
A pressure as low as 4×10-11Pa has been obtained. Suppose a chamber contains helium at this pressure and at temperature 380K. Estimate the collision time (tau) for helium in the chamber. Take the diameter of a helium molecule to be 1×10-10m.
