Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

Question 1 The sun generates its energy through nuclear fusion, making helium from hydrogen. The main process by which this happens, called the proton-proton chain, goes as follows: • Two protons come together to create deuterium, a positron, a neutrino, and energy: p + p→D+e++v+ energy • The deuterium fuses with another proton to make ³He: D + p→→ ³He + energy • Fianlly, 4He is produced by fusing two ³He nuclei together: ³He + 3 He→ 4He+p+p+ energy What is the total energy released during the creation of one 4He nucleus? Give your answer in MeV, and remember that you need to make two ³He nuclei in the process. Be sure to use at least five significant figures for your masses, but your final answer should have three or four sig figs.
