Question
- A. space-43-mcq-02 evidence: red-shifted absorption lines correctly supports (Physics only) Explain that the further away a galaxy is, the faster it is moving away by using observation, spectrum, signal, data in Red-shift and evidence for an expanding universe.
- B. space-43-mcq-02 orbitrotation error: this swaps orbit with rotation and misses evidence reasoning.
- C. space-43-mcq-02 scalemix error: this mixes planet star galaxy universe scale and loses the boundary.
- D. space-43-mcq-02 evidencegap error: this gives a vague astronomy fact but omits the named evidence stage or object.
Answer
The correct answer is: space-43-mcq-02 evidence: red-shifted absorption lines correctly supports (Physics only) Explain that the further away a galaxy is, the faster it is moving away by using observation, spectrum, signal, data in Red-shift and evidence for an expanding universe..
Explanation
Route aee40c: space-43-mcq-02 evidence: red-shifted absorption lines correctly supports (Physics only) Explain that the further away a galaxy is, the faster it is moving away by using observation, spectrum, signal, data in Red-shift and evidence for an expanding universe. is correct because it matches (Physics only) Explain that the further away a galaxy is, the faster it is moving away. in Red-shift. Check the other options against the wording of the stem; they either describe a different source, process, unit, field, graph feature or concept boundary. This explanation supports the marked correct option directly and keeps the MCQ anchored to the learning objective.
Common mistake
Red-shift and evidence for an expanding universe common mistake 1
Giving a vague answer instead of directly addressing: (Physics only) Explain that the further away a galaxy is, the faster it is moving away..
Answer by clearly explaining how to (Physics only) Explain that the further away a galaxy is, the faster it is moving away..
