Question

explain how the balloon activity modeled hubbles law?

Explanation:

The surface of a balloon represents the expanding universe. Dots on the balloon (like galaxies) move apart as the balloon inflates. The further a dot is from a reference - dot, the faster it appears to move away, similar to how galaxies move away from us at speeds proportional to their distance according to Hubble's law.

Answer:

The balloon's surface expansion with dots representing galaxies shows that more distant 'galaxies' (dots) move away faster, mirroring Hubble's law.
