B) Describe the protom-proton cycle, with all particles created and annihilated.
C) draw a cross- sectional map of the dun, label its different regions and what energy transfer mechanicm dominates at each location?
A) what is the Energy production mechanism taking place in the Sun that maintains its luminosity?
A - nuclear fusion
B - 2 protons collide releasing a positron, deuterium and a gamma ray. The deuterium collides with another proton to give Helium-3 nuclei. Two He-3 then collide to produce helium-4 and two protons which are recycled in the chain. The neutrinos escape unharmed from the sun. The positron will collide with an electron and annihalate itself producing gamma rays.
