SMOKE ALARM case: alpha source in chamber produces evidence from ionisation current. Which option best answers the objective "Use E = mc2 to calculate binding energy." for Mass and energy, while reaching the conclusion about sealed source?.
- A.nuc-103-smoke-alarm: Link alpha source in chamber to ionisation current and conclude sealed source for Mass and energy.
- B.nuc-103-smoke-alarm: Ignore ionisation current and answer with an unrelated Radioactivity recall phrase.
- C.nuc-103-smoke-alarm: Swap the required nuclear distinction and claim sealed source without evidence.
- D.nuc-103-smoke-alarm: Use a calculation label only, without applying use E = mc2 to calculate binding energy..
Model answer
What a good answer should say
- The correct option is nuc-103-smoke-alarm: Link alpha source in chamber to ionisation current and conclude sealed source for Mass and energy.
Explanation
Why this works
It is correct because the smoke alarm context uses ionisation current to support use E = mc2 to calculate binding energy. in Mass and energy.
The distractors fail because they either ignore the evidence, swap a nuclear concept boundary, or give a label without the required A-Level Physics reasoning.
