ntrifugation magnetic separation
2 answers:
Filtering the homogeneous mixture to get the materials out and boil away any water
Answer: <u>Evaporation</u>
<u>Explanation:</u>
A homogeneous mixture contains components in same proportion through out the sample.
<u>screening: </u>It is the filtration method for non-homogeneous mixture having different particles size.
Evaporation: It is a method of separation for homogeneous mixture of soluble solute from a solvent.
<u>centrifugation: </u>It is a method of separation for non-homogeneous mixture having different densities.
<u>magnetic separation: </u>It is a method of separation for non-homogeneous mixture having a component with magnetic properties.

I just had this question, the awnser is A.
The answer is a because if you look really close
Answer:
40 km/h
Explanation:
First...
Look at the formula speed is equal to the distance over time or s = d/t.
Next...
Use the formula: 240/6.0
Finally...
Solve: 40
So the answer: 40 km/h
Answer:
thick wire and cold temperatures
Acceleration (magnitude anyway) = (change in speed) / (time for the change) .
Change in speed = (10 - 30) = -20 m/s
Time for the change = 4.0sec
Magnitude of acceleration = -20/4 = <em>-5 m/s² </em>
