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?

The velocity of sound wave in air at 35°c is 353m/s, calculate the velocity of sound at 46°c

The inverse square law applies to: intensity of sound gravitational force intensity of light electric force magnetic force
