Two vehicles A and B are moving in same direcuion with the velocity 10 ms-1and 12ms-1respectively. Calculate the relative velocity of A with respect to B. If both vehicles are travelling in opposite direction, what will he the relative velocity?​

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.
