Two satellites of equal mass are each in a circular orbit around the earth. The orbit of satellite \(\mathrm{A}\) has radius \(r_{A}\), and the orbit of satellite \(\mathrm{B}\) has radius \(r_{B}=2 r_{A}\). Find the ratio of their

(a) speeds

(b) periods

(c) kinetic energies

(d) potential energies

(e) total energies.
