21. (II) A light-year is the distance light travels in one year (at speed = 2.998 X 10^8m/s). (a) How many meters are there in 1.00 light-year? (b) An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 X 10^8km. How many AU are there in 1.00 light-year? (c) What is the speed of light in AU/h?
