real life examples

[MrsC1165]

Anyone have any ideas of real life examples of where it would be necessary to use a radical expression and a rational exponent. I'm looking for two different examples; one for each.

Thanks, Lisa

One example of a radical expression (yes, it is a little confusing) is the rate of diffusion of a gas. While you probably won't need this formula, it is as follows: "The rate of diffusion of a gas is inversely proportional to the square root of its molecular weight". Yes, that is confusing and I doubt you will need that formula, but that shoud help.
