sy w - Chapter 6: Homework 1 In a location in outer space far from all other objects, a nucleus whose mass is 3.620124 x 10-25 kg and that is initially at rest undergoes spontaneous alpha decay. The original nucleus disappears, and two new particles appear: a He-4 nucleus of mass 6.640678 x 10"27 kg (an alpha particle consisting of two protons and two Question 10 of 10 neutrons) and a new nucleus of mass 3.553550 x 10-25 kg. These new particles move far away from each other, 7.5 / 10 because they repel each other electrically (both are positively charged). seven significant figures.) Because the calculations involve the small difference of (comparatively) large numbers, you need to keep seven 3.253455e-8 significant figures in your calculations, and you need to use the more accurate value for the speed of light, 2.9979246e8 m/s.
