Astronomers observe two separate solar systems each consisting of a planet orbiting a sun. The two orbits are circular and have
the same radius R. It is determined that the planets have angular momenta of the same magnitude L about their suns, and that the orbital periods are in the ratio of three to one; i.e., T1 = 3T2. The ratio m1/m2 of the masses of the two planets is (A) 1
(C) (3)^1/2
(C) 2
(D) 3
(E) 9
The tiny ripples on the soup are not only similar to wind-generated waves ... they ARE wind-generated waves. This is a big part of the reason why they bear such an uncanny resemblance.
