Exam-style question
Try this first
In a medical tracer risk assessment, which option best applies the AQA A-Level Physics objective to use E = mc2 to calculate binding energy. while keeping isotope notation, radiation type, activity and safety reasoning distinct?.
- A.nuclear-case-10: Apply Use E = mc2 to calculate binding energy. in Mass and energy.
- B.nuclear-case-10: Mix Mass and energy with a different nuclear model and ignore the measured quantity.
- C.nuclear-case-10: Use a generic radiation phrase without isotope, activity or count-rate reasoning.
- D.nuclear-case-10: Treat Radioactivity as simple recall and omit the A-Level Physics distinction.
Model answer
What a good answer should say
- The correct option is nuclear-case-10: Apply Use E = mc2 to calculate binding energy.
- in Mass and energy.
Explanation
Why this works
It is correct because it directly supports the approved objective: Use E = mc2 to calculate binding energy. The other options are weaker because they confuse radiation type, isotope structure, count-rate interpretation, half-life reasoning, shielding, contamination or irradiation with a nearby but different nuclear physics idea.
