Which conclusion is most creditworthy for Describe Observations From Cathode Ray Experiments?.
- A.A. The conclusion follows from describe observations from cathode ray experiments and states the physical consequence for Cathode rays without changing the assessed idea.
- B.B. The conclusion repeats the question but gives no physics reason.
- C.C. The conclusion is based on a related but different A-Level Physics process.
- D.D. The conclusion is longer, but it does not use the tested relationship.
Model answer
What a good answer should say
- Energy Account answer aa84ff: A.
- The conclusion follows from describe observations from cathode ray experiments and states the physical consequence for Cathode rays without changing the assessed idea.
- 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 conclusion is most creditworthy for 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 Energy Account answer aa84ff: 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.
