•Question 7   (1 point) The sun produces energy by converting mass into energy via a fusion process. How much energy is produced when the sun converts 1 kg of mass into energy? Also note that when checking units the unit of energy called a "Joule" is shorthand for a "kg m2/s2".
a.   6 x 1016 J  b.   9 x 108 J   c. 6 x 1016 J   d. 3 x 1016 J   e. 9 x 1016 J    •E = mc2.  Mass = 1 kg, c = 3x108 m/s.  So E= 1kg x (3x108 m/s)2
