The footprints of a dinosaur and the burrow of an ancient shrimp are examples of which kind of fossils

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.

The term gas is limited to those substances that exist in the gaseous state at
