In Larry Niven's science-fiction novel Ringworld, a rigid ring of material rotates about a star. The inhabitants of this ring world live on the starlit inner surface of the ring (where it is always noon). The tangential speed of the ring is 1.2 x 10^6 m/s, its radius is 1.52 x 10^11 m, and the star has a mass of 1.6 x 10^32 kg. A. What is the length of a year on this planet? Earth days (i. e., 24-hour periods)B. What is the apparent weight of an inhabitant of Ringworld relative to his weight on Earth? (apparent weight/Earth weight)C. What would this ratio be for the same inhabitant if there were no star in the center? (apparent weight/Earth weight)
