While researching a topic, a student has taken the following notes:
<ul> <li>Hubble's law relates a galaxy's distance to its recession speed.</li> <li>It states that more distant galaxies recede faster.</li> <li>The relationship was first reported by Edwin Hubble in 1929.</li> <li>It provides evidence for the expansion of the universe.</li> <li>The slope of the relation is called the Hubble constant.</li> </ul> The student wants to emphasize the cosmological significance of Hubble's law. Which choice most effectively uses relevant information from the notes to accomplish this goal?Which choice most effectively makes the student's point?
- A
The slope is called the Hubble constant.
- B
The law was reported in 1929.
- Ccheck_circle
Hubble's law, which states that more distant galaxies recede faster, provides key evidence for the expansion of the universe.
- D
Edwin Hubble reported the law in 1929.
Explanation
The goal is cosmological significance. Choice B states the law and its implication for cosmic expansion. The others address provenance or terminology.
