Ancient people looked to the night sky and saw the same patterns of stars in different seasons. One star pattern would come into view in early spring each year. Another star pattern would appear in summer, and so forth. People used these patterns to help them figure out when to plant and harvest crops. Before there were calendars, people used star patterns to help them plan.
Ancient people also used star patterns to help them find their way from place to place. Stars seem to move across the sky at night. By tracking the apparent movements of stars, people could navigate on land and on sea.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25βc)? assume that d for this molecule is 1Γ₯=10β10m. take the total mass of an n2 molecule to be mn2=4.65Γ10β26kg. 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.
