With which type of galaxy is a small galaxy most likely to merge? Select the two correct answers. (1 point)
a nearby galaxy Da much larger galaxy a fast-moving galaxy an equal-sized galaxy
A nearby galaxy and a much larger galaxy are the two correct answers to this question.
A small galaxy is most likely to merge with two types of galaxies:
1) A nearby galaxy
2) A much larger galaxy
To determine the type of galaxy with which a small galaxy is most likely to merge, we need to consider the interactions between galaxies. Galaxies can merge due to gravitational attraction between them, leading to the formation of larger galaxies. Two factors play a significant role in determining the likelihood of a merger: the size of the galaxies and their relative velocities.
The two correct answers are:
1. A larger galaxy: In general, smaller galaxies are more likely to merge with larger galaxies due to the gravitational pull exerted by the larger galaxy. The larger galaxy's mass and gravitational force can overwhelm the smaller galaxy, causing them to merge.
2. An equal-sized galaxy: While mergers between large and small galaxies are more common, mergers between similar-sized galaxies can also occur. If two galaxies of comparable size come close enough to each other, gravitational interactions can cause them to merge, resulting in the formation of a new, larger galaxy.
It's important to note that the other options, a nearby galaxy and a fast-moving galaxy, do not necessarily determine the likelihood of a merger. The proximity of a galaxy or its speed alone does not provide enough information about the dynamics of their interaction and merger likelihood.
