Answer:
It is not considered as a vacuum because the space around is not empty the space around it is filled with air like example the space has no air.
Answer:
b) 47ml
Explanation:
The beaker would look like this:
60 mL
50 mL
------- The bottom of the meniscus is here
40 mL
30 mL
So <u>we have between 40 and 50 mL</u>. There are 10 mL of "distance" between those two values, and three fourths of that difference is (10 * 3/4) 7.5 mL.
So <em>the volume is 47.5 mL</em>, but because the measurement instrument (the beaker) does not handle decimals, the value we should report is 47 mL.
Answer:
More than 2,000 Years Ago, the Greek philosopher Aristotle suggested a model of the solar system. Aristotle's model was geocentric, or Earth-centered. In the model. the sun, stars, planets revolved around the Earth. In 150 AD an astrologer named Ptolemy began to support Aristotle's geocentric model.
In 1543 AD, an astronomer named Copernicus proposed a heliocentric model of the solar system. In this model, the planets revolve around the sun. Due to the invention of the telescope, the solar system could be explored in more detail. Galileo used the telescope to support Copernicus's theory of the sun being the center of the universe.
In the late 1500's, Kepler developed a law that explained planetary motion. Kepler's law is so accurate we still use them today.

Can you show me the rest of the question? I can not see it. Also, I know this is multiple choice fill in the blanks so I might be wrong. I hope that this helped though. This took a lot of research. The websites I used are commented down below. |

Explanation:
Given parameters:
Dimension = 8.5in²
we are to convert from in² to cm²
in² = in x in
cm² = cm x cm
1 in = 2.54cm
Using dimensional analysis;
8.5in² x 
= 54.84cm²
We solved this problem using dimensional analysis where we multiplied the unit with 1.
