The Sun: A Nuclear Powerhouse

A self-checking practice quiz on the Sun as a nuclear powerhouse: nuclear fusion as its energy source, the proton-proton chain, mass-energy equivalence, hydrostatic equilibrium, the Sun’s lifetime, solar neutrinos, and how we study the interior. Every question is multiple choice and shown one at a time, and the set is drawn fresh each time you take it. At the end you receive a report showing how many you answered correctly.
