When a bat hits a ball, what is the impulse? the force multiplied by the time the objects are in contact the mass multiplied by the acceleration the change in velocity multiplied by the force the mass multiplied by the force

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.
