Which response best uses evidence or a diagram feature to support Describe Observations From Cathode Ray Experiments?.
- A.A. It points to the relevant observation, graph feature, field direction, or measurement and links it directly to describe observations from cathode ray experiments.
- 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
- Unit Check answer 60603b: A.
- It points to the relevant observation, graph feature, field direction, or measurement and links it directly to describe observations from cathode ray experiments.
- is correct because it matches Describe observations from cathode ray experiments.
- through Michelson-Morley, special relativity, time dilation, de Broglie wavelength.
Explanation
Why this works
Stem being answered: Which response best uses evidence or a diagram feature to support Describe Observations From Cathode Ray Experiments? Route focus: turning-points-in-physics / The Discovery Of The Electron.
Key vocabulary for this item: observations, cathode, ray, experiments. Option check: keep Unit Check answer 60603b: A because it matches the stem; reject alternatives that change observations, cathode, ray 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.
