NUCLEAR RADIUS GRAPH case: cube-root mass number produces evidence from straight-line fit. Which option best answers the objective "Calculate nuclear density from mass and radius data." for Nuclear radius, while reaching the conclusion about femtometre scale?.
- A.nuc-116-nuclear-radius-graph: Link cube-root mass number to straight-line fit and conclude femtometre scale for Nuclear radius.
- B.nuc-116-nuclear-radius-graph: Ignore straight-line fit and answer with an unrelated Radioactivity recall phrase.
- C.nuc-116-nuclear-radius-graph: Swap the required nuclear distinction and claim femtometre scale without evidence.
- D.nuc-116-nuclear-radius-graph: Use a calculation label only, without applying calculate nuclear density from mass and radius data..
Model answer
What a good answer should say
- The correct option is nuc-116-nuclear-radius-graph: Link cube-root mass number to straight-line fit and conclude femtometre scale for Nuclear radius.
Explanation
Why this works
It is correct because the nuclear radius graph context uses straight-line fit to support calculate nuclear density from mass and radius data. in Nuclear radius.
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.
