Answer:

  • B. 12

Step-by-step explanation:

Since Z is midpoint of SR and Y is midpoint of QR, so as per triangle midpoint theorem ZY is parallel to SQ and measures half of its value:

  • SQ = 2ZY
  • 3x - 8 = 2(x + 2)
  • 3x - 8 = 2x + 4
  • 3x - 2x = 4 + 8
  • x = 12

Correct answer choice is B

Answers

1. Which describes the work of Nicolaus Copernicus?
c. developing a heliocentric theory



2. Which was not an accomplishment of Galileo Galilei?

c. confirming that the earth revolves around the sun



3. Which best describes the influence of Isaac Newton's theory of universal gravity?

It showed that the universe follows a set of predictable rules

Final answer:

Nicolaus Copernicus developed the heliocentric theory. Galileo Galilei did not write the Principia Mathematica but he did confirm the earth revolves around the sun with his improved telescope. Isaac Newton's theory of universal gravitation significantly advanced our understanding of the physical universe.

Explanation:

Nicolaus Copernicus is renowned for developing the heliocentric theory, according to which the sun is the centre of the universe and the earth and other planets revolve around it. This answer corresponds to option C in your question. Galileo Galilei, on the other hand, did not write the Principia Mathematica. This work was written by Sir Isaac Newton, and thus corresponds to option B of your second question. Galileo is well-known for advancing the telescope technology, and his observations confirmed the heliocentric system.

As for your third question, Isaac Newton's theory of universal gravitation revolutionized our understanding of the physical universe. While it did lead to new insights into light, it's most significant contribution is perhaps its explanation of how objects in the universe are attracted to each other, demonstrating that the same forces are at work in the heavens and on earth.
