From Keplers discovery, scientists were also able to infer that the closer a satellite is to an object, the stronger the force of attraction, hence it must travel faster in order to maintain orbit. Relying on this formula, we are able to see that the velocity required for orbit is equal to the square root of the distance from the object to the center of the Earth times the acceleration due to gravity at that distance. So if we wanted to put a satellite in a circular orbit at 500 km above the surface (what scientists would call a Low Earth Orbit LEO), it would need a speed of ((6.67 x 10-11 * 6.0 x 1024)/(6900000))1/2 or 7615.77 m/s. So really, a satellites ability to maintain its orbit comes down to a balance between two factors: its velocity (or the speed at which it would travel in a straight line), and the gravitational pull between the satellite and the planet it orbits.

B. A chapter that offers social commentary and is interwoven with narrative chapters
Explanation:
The complete question is;
Who said the following words
What's more to do, Which would be planted newly with the time,— As calling home our exile friends abroad, That fled the snares of watchful tyranny; Producing forth the cruel ministers Of this dead butcher, and his fiend-like queen,— Who, as 'tis thought, by self and violent hands Took off her life;
Answer
These lines are taken from Macbeth, a play written by famous Shakespeare.
These words had been said by Malcolm at the end of the play.
He meant that since Macbeth had dead, so now there was a new regime for Scotland. The king of that regime was Malcolm and he would call back his friends to Scotland. He also scolded Lady Macbeth for her work and that she had taken her own life
A=Edgar Poe didn't write "just anything" that would sell. If he did that, we probably wouldn't have ever heard of him for several reasons which are ultimately unimporatant to this question.
B=He claimed his first love was poetry, and he considered himself a poet before a regular, ordinary writer, but given the way the choices are worded, I'd say that B is still, with this in consideration, not the answer.
C=Edgar Poe did fabricate his personal life one time, when he created a backstory for his alias Arthur Gordon Pym.
D=True, he did invent it before Sir Arthur Conan Doyle ripped off Poe's detective C. Auguste Dupin.
E=Edgar Allan Poe was never insane. He was not that kind of man. He was more philosophical and aristocratic. Although in his youth he had toyed with an alcohol vice, he overcame it in his later years. He is only (and falsely) known for an alcoholic past because after Poe died, Poe's editor, Rufus Griswald slandered Poe and re-wrote Poe's biography, altering history away from the truth. Edgar Poe was never the "madman-alcoholic" that some people wrongfully believe he was.
