Answer the following question given this paragraph: Every object has a center of gravity . The center of gravity is the point at which the entire weight of a body may be considered to be concentrated; if supported at this point, the body would remain in equilibrium in any position. For example, if we were discussing a 12-inch ruler, the center of gravity for the ruler would be at the center of the 6-inch line. You could put your finger directly under the 6-inch line to hold the ruler and it would not fall either left or right. If you placed your finger underneath any other place on the ruler, it would fall off to one side or the other. Q: What do you call the point at which the entire weight of a body may be considered to be concentrated? Choices: - center of earth - complex of gravity - direction of gravity - center of gravity A:
(Answer)
center of gravity

They beat on their chest, dash back and forth, and pound the ground with their hands. Q: In many species, display behaviors, like a gorilla beating on its chest, are used instead of actual physical attacks to show what? Choices: - dominance - friction - stress - aggression A:
(A).

Ques:Answer the following question given this paragraph: The universe contains all the matter and energy that exists and all of space and time. We are always learning more about the universe. In the early 20th century, Edwin Hubble used powerful telescopes to show that some distant specks of light seen through telescopes are actually other galaxies. ( Figure below ) Hubble discovered that the Andromeda Nebula is over 2 million light years away. This is many times farther than the farthest distances we had measured before. He realized that galaxies were collections of millions or billions of stars. Hubble also measured the distances to hundreds of galaxies. Today, we know that the universe contains about a hundred billion galaxies. Q: Who discovered that the andromeda nebula is over 2 million light years away Choices: - richter hubble - smith hubble - mills hubble - edwin hubble A:

Ans:edwin hubble
Answer the following question given this paragraph: The standard unit for mass is the kilogram . The kilogram's standard is a block of platinum-iridium metal kept near Paris, France. Other countries, of course, keep copies. A kilogram is denoted "kg" and is a multiple of the smaller unit of mass, the gram ("g"). Q: What is the standard unit for mass? Choices: - ounce - meter - pound - kilogram A:
kilogram
