Some historians compared an old map of a river in a rural area of the Piney Woods to a current map of the same river. The historians observed that the old map showed the river with a different flow pattern from the current map. Which process below explains the change in the river's flow?

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.
