Astronomers define a parsec (short for parallax second) to be the distance at which 1 astronomical unit subtends an angle of 1 second. The astronomical unit (AU) was defined in the precedingproblem, and in angular measure 1 degree = 60 minutes and 1 minute =60 seconds of arc. Find the conversion factors that relate (a) parsecs to AU; (b) parsecs to m.
