Newton's theory of universal gravitation states that every massive particle in the universe attracts every other massive particle with a force proportional to the mass of the particles and their proximity to one another. Consequently, cosmologists would expect that calculations based on this theory would yield an accurate measure of the mass in the universe; in fact, though, the total amount of observable matter in the universe does not contain enough mass to account for the organization of the universe into clusters of galaxies. To explain this discrepancy, cosmologists have developed the theory of "dark matter:" they postulate that the missing mass consists of elementary particles too small to be detected by electromagnetic radiation, and that these particles provide the mass necessary to hold the universe together. According to available evidence, these particles can only account for a maximum of 20 percent of the missing mass in the universe, yet their existence brings us one important step closer to solving the mystery of the missing matter.

According to the passage, which of the following factors is believed to help account for the missing mass in the universe?

A. Massive particles with a force proportional to the mass of the particles attract additional mass to the universe.
B. Tiny particles that are not currently observable by humans compose some of the missing mass.
C. "Dark matter" adheres to mass and causes it to expand. G
D. alaxies organize themselves into clusters to compensate for the lack of other mass in the universe.
E. The proximity of certain particles to each other forces an attraction that creates mass.



For the following question, consider each of the choices separately and select all that apply

The passage suggests that a massive particle would be most likely to attract another particle

❑ with a force related to the mass of each particle.
❑ at a distance related to the mass of each particle.
❑ by using an elementary particle as an intermediary.

EXPLANATION QUESTION #1

According to the passage, cosmologists believe that the missing mass is partially accounted for by elementary particles too small to be detected by electromagnetic radiation. Choice (B) rephrases this statement, and so it's the best response. Choices (A) and (E) recycle words from the first sentence of the passage, but they have different meanings; moreover, the first sentence is referring to the problem the cosmologists are trying to solve, whereas the question asks for the solution. Choice (C) is wrong because the passage doesn't say anything about dark matter causing the expansion. Choice (D) also doesn't work: The galaxies are the evidence that shows that Newton's theory has a problem, not the solution.

EXPLANATION QUESTION #2


Newton's theory states that massive particles attract each other with a force proportional to the mass of the particles and their proximity to one another, so the strength with which the particles attract each other is related to their mass and the distance between them. Choice (B) is tempting, but incorrect: It relates distance and massto each other, when it needs to relate them both to force. Choice (C) is also incorrect, because it uses the idea of elementary particles presented later in the passage out of context-the passage doesn't say that these particles are used as intermediaries between massive particles. Choice (A) is supported by the passage: It forms a relationship between force and mass, which is one of the relationships contained in the theory.

Hey Carcass

i didn't get the third question like the paragragh is related to Missing Mass and the third question is talking about country. How they are relatable ?

The above passage is whole about "missing mass" they haven't mentioned anything about coal

You are right sir. I went off balance. Forgive me

The last question is NOT related to the passage. The book was not so clear with the stem and I missed it too

My bad. Apologize

conformation ? or confIrmation?

I do not know what you meant

Also sarcastic for what reason ?


I did wrong and I think it is correct to apologize for the wrong doing.

Then, tell me what you thought :blushing:

No worries Brother. We all do mistakes similarly i wrote conformation instead of confirmation. I have learned alot from your blogs and through your comments. Instead of apology from your side, i think i should be more thankful to you. Thanks Brother for helping us out really means alot 😊!!!
