(a) Suppose a star is 3.45 x 101 m from Earth. Imagine a pulse of radio waves is emitted toward Earth from the surface of this star. How long (in years) would it take to reach Earth? years (b) The Sun is 1.50 x 10¹1 m from Earth. How long (in minutes) does it take sunlight to reach Earth? minutes (c) The Moon is 3.84 x 100 m from Earth. How long (in s) does it take for a high-intensity laser beam to travel from Earth to the Moon and back?
