With which type of galaxy is a small galaxy most likely to merge? Select the two correct answers.
a nearby galaxy a nearby galaxy a much larger galaxy a much larger galaxy a fast-moving galaxy a fast-moving galaxy an equal-sized galaxy
A small galaxy is most likely to merge with a much larger galaxy and an equal-sized galaxy.
A small galaxy is most likely to merge with a nearby galaxy and a much larger galaxy.
To determine with which type of galaxy a small galaxy is most likely to merge, we need to consider the factors that influence galactic mergers. Two important factors to consider are the proximity of the galaxies and their relative sizes.
1. Proximity: Galaxies that are close to each other are more likely to interact and eventually merge due to the gravitational attraction between them.
2. Size: Larger galaxies have a stronger gravitational pull, which makes them more likely to attract and merge with smaller galaxies.
Based on these factors, the two correct answers are:
1. A nearby galaxy: If a small galaxy is located near another galaxy, they are more likely to merge due to the close proximity.
2. A much larger galaxy: Small galaxies are more likely to merge with much larger galaxies because the larger galaxy's gravitational pull is stronger and can eventually absorb the smaller galaxy.
Therefore, the correct answers are a nearby galaxy and a much larger galaxy.
