Use the scenario to answer the question.
A student makes a chart about galaxies and mentions that the universe consists of many galaxies such as the Andromeda galaxy and the Milky Way galaxy.
Which statement is true about these two galaxies?
A. They are both moving away from each other.
B. They both exert a strong gravitational pull on each other.
C. The Milky Way galaxy is larger than the Andromeda galaxy.
D. The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
1. They both exert a strong gravitational pull on each other.
2. a black hole
3. pinwheel
4. Star A will have a higher apparent magnitude because it at a lesser distance.
5. Both orbit the sun.
6. Saturn.
7. determine temperature, chemical composition, and speed
8. treating medical conditions
9. Some scientists think that the universe will not keep expanding forever.
10. After the universe reaches its expansion limit, gravity will pull it all back together.
11. What is the future of the universe?
12. big bang theory
13. There is a red shift, which means that the star is moving away from the sun.
14. Global positioning can provide high precision measurements so that small changes over time could be seen.
15. new lightweight blankets developed in the space program
16. written response
Not a gamer girl is 100% correct... thank you :)
10. There is a red shift, which means that the star is moving away from the sun
To answer this question, we can start by identifying the characteristics of the two galaxies mentioned: the Andromeda galaxy and the Milky Way galaxy.
To determine whether the galaxies are moving away or exerting a strong gravitational pull on each other, we need to consider their relative motion. The current understanding is that most galaxies in the universe are moving away from each other due to the expansion of the universe. This is known as the Hubble's law, which states that galaxies are moving away from us, and from each other, at speeds proportional to their distance. Therefore, option A, "They are both moving away from each other," is correct.
To determine which galaxy is larger, we need additional information. The size of a galaxy can vary, and without specific data, it is challenging to compare the sizes of two galaxies accurately. Therefore, we cannot conclude option C, "The Milky Way galaxy is larger than the Andromeda galaxy," is true.
Lastly, to determine whether the Milky Way is a spiral galaxy and the Andromeda galaxy is not, we need to examine their respective classifications. The Milky Way is indeed classified as a spiral galaxy, characterized by its spiral arms and a central bulge, while the Andromeda galaxy is also classified as a spiral galaxy. Therefore, option D, "The Milky Way is a spiral galaxy, and the Andromeda galaxy is not," is incorrect.
Based on this analysis, the statement that is true about these two galaxies is option A, "They are both moving away from each other."
1. pinwheel
2. A black hole
3. Both orbit the sun (I Think)
4. Saturn
5. Noticing the gravity will eventually pull all the planets and the universe back together.
6. After the universe reaches its expansion limit, gravity will pull it all back together.
7. What is the future of the universe ( I think)
8. Big Bang Theory (I think)
9. Some scientists think that the universe will not keep expanding forever. (I Think)
Come up with the last two yourself
Also, not my fault if any of these are wrong, You should have gotten the answers yourself
From Internet:
Both the Milky Way and the Andromeda galaxy are giant spiral galaxies in our local universe. And in about 4 billion years, the Milky Way and Andromeda will collide in a gravitational sumo match that will ultimately bind them forever.
This should help.
