Consider a 2-kg bowling ball sitting on top of a building that is 40 meters tall. It falls to the ground. How much gravitational potential energy (GPE) does the bowling ball have? The equation for GPE is mass x gravity constant x height. The gravity constant is 9.8.

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.
