Which of the following would be an accurate picture of the earth during the summer time of the northern hemisphere?

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 activation energy for a(n) is quite large and usually takes extra energy from the environment, it is normally not a natural spontaneous process. combustion reaction endothermic reaction exothermic reaction catalyzed reaction
