What is a logical way that you could begin to investigate why your tire had low air pressure? look to see if there is a hole in the tire. feel the tire for air escaping from it. place the bike in a warm location to see if the tire pressure increases. apply an outside pressure to the tire and listen for air escaping from the tire.

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.
