Answer:
to separate the compounds by gravity
Explanation:
Centrifuging is the process of separating compound in a liquid mixture by means of gravity and settling. This makes use of the density principle. In the process, the sample is added to the centrifuge. This is then rotated at a certain speed, say 50 rpm. The circular motion creates a force of gravity that pulls the compounds downwards. This then separate the compounds. The heaviest and most dense go down first, then the lighter particles on the top.
Answer: D. gravity
Explanation:
An airplane in flight is acted on by four forces: lift, the upward acting force; gravity, the downward acting force; thrust, the forward acting force; and drag, the backward acting force (also called wind resistance).
To solve this problem, let us first understand what does
mega meters mean. Now by definition, mega means a factor of one million which
is a unit prefix in Metric Systems of units. It is denoted by the unit symbol
M.
So for example if we have a mega of something, it means a
million of something. So in this case, if we have 1 mega meter, what it means
is 1 million meter, which is written as:
1 mega meter = 1,000,000 meter
To show the decimal points:
1.0 mega meter = 1,000,000.0 meter
So we see that the decimal point move 6 zeroes to the
right, therefore the direction is to the right.
Answer:
<span>6 places to the right</span>
