QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Nuclear Reactions.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
Calculate the energy released (in MeV) when 1 amu of mass is converted to energy. (Given: 1 amu = 1.6605 × 10⁻²⁷ kg, c = 3.00 × 10⁸ m/s, 1 eV = 1.602 × 10⁻¹⁹ J)
Calculate the mass defect (in amu) for a helium-4 nucleus if the mass of 2 protons is 2.0146 amu, 2 neutrons is 2.0173 amu, and the actual mass of the nucleus is 4.0026 amu.
