I have finally been invited to a party at Nick's house. He's the most popular guy in school and has really cool parties. Everybody there will be drinking beer, but I'm going to go. I really want to fit in. First state the health risk and then rewrite the behavior or choice made to include a healthy decision.

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?
