Igcse Model Questions Vol1 2023 Physics Question 26
Practice objective / multiple choice question 26 from the 2023 Igcse Model Questions Vol1 Physics examination.
A sample of uranium‑235 weighing \(0.5\ \text{g}\) is used as fuel in a reactor that delivers a constant power of \(2.0\ \text{kW}\). Each fission of a \(^{235}\text{U}\) nucleus releases an average energy of \(200\ \text{MeV}\). Assuming all the released energy appears as the reactor power, what fraction of the original nuclei have fissioned after \(10\ \text{min}\)? Give your answer in scientific notation to two significant figures.
