Which response best uses evidence or a diagram feature to support Describe Rutherford Alpha Scattering Observations?.
- A.A. It points to the relevant observation, graph feature, field direction, or measurement and links it directly to describe rutherford alpha scattering observations.
- B.B. It quotes a number or feature but does not say what it proves.
- C.C. It draws a conclusion from evidence that belongs to another subtopic.
- D.D. It ignores the evidence and gives only a memorised sentence.
Model answer
What a good answer should say
- Signal Path answer 992b1b: A.
- It points to the relevant observation, graph feature, field direction, or measurement and links it directly to describe rutherford alpha scattering observations.
- is correct because it matches Describe Rutherford alpha scattering observations.
- through alpha emission, beta decay, gamma radiation, half-life.
Explanation
Why this works
Stem being answered: Which response best uses evidence or a diagram feature to support Describe Rutherford Alpha Scattering Observations? Route focus: nuclear-physics / Radioactivity.
Key vocabulary for this item: rutherford, alpha, scattering, observations. Option check: keep Signal Path answer 992b1b: A because it matches the stem; reject alternatives that change rutherford, alpha, scattering or use a neighbouring model.
The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
