Distillation
Explanation:
The name of the process used to refine oil into different products is called distillation. A refinery has huge distillation columns where is separated into its different fractions.
- Distillation is a separation technique in which a mixture such as crude oil is separated into its fractions.
- The components of the mixture must have an appreciable boiling point difference.
- After distillation, oil is separated into difference components such as heavy oil, natural gas, kerosene, gasoline e.t.c.
- The liquid with the least boiling point rises up in the column first and is collected.

Filtering the homogeneous mixture to get the materials out and boil away any water
The ball took half of the total time ... 4 seconds ... to reach its highest
point, where it began to fall back down to the point of release.
At its highest point, its velocity changed from upward to downward.
At that instant, its velocity was zero.
The acceleration of gravity is 9.8 m/s². That means that an object that's
acted on only by gravity gains 9.8 m/s of downward speed every second.
-- If the object is falling downward, it moves 9.8 m/s faster every second.
-- If the object is tossed upward, it moves 9.8 m/s slower every second.
The ball took 4 seconds to lose all of its upward speed. So it must have
been thrown upward at (4 x 9.8 m/s) = 39.2 m/s .
(That's about 87.7 mph straight up. Somebody had an amazing pitching arm.)
Answer:
for students to do nothing
Explanation:
because doing nothing is not a course goal
Answer:
0.5m/s2
Explanation:
acceleration= change in velocity/time taken
= v - u/ t
= 10-5/10
=5/10
= 0.5m/s2
