Hi there!
Kinetic energy can be calculated using the following:
Where:
KE = Kinetic energy (J)
m = mass (kg)
v = velocity (m/s)
Plug in the given values:
<span>Suspension, chemistry definition is a heterogenous
mixture, meaning one substance is different from another, when mixed, either of
the substance (particularly the solid one), do not mix evenly. It could clearly
be seen when one mixes a solution in a suspension state because it forms a
cloudy solution, Best example of this is mud. In mud, though there is a mixture
of solid and liquid, there is still evident traces of solid particles that do
not mix evenly in the solution.</span>
And the answer is True, It has the most of <span>complex level of organization within large organisms, such as elephants, is the organ system.

Answer:
Explanation:
Since there is no friction angular momentum is conserved. The formula for angular momentum thet will be useful in this case is 
. If we call 1 the situation when the student is at the rim and 2 the situation when the student is at 
from the center, then we have:
Or:
And we want to calculate:
The total moment of inertia will be the sum of the moment of intertia of the disk of mass 
and radius 
, which is 
, and the moment of intertia of the student of mass 
at position 
(which will be 
or ) will be 
, so we will have:
or:
which for our values is:
Inertia is a property of all the objects. Galileo stated that inertia is proportional to mass. Therefore, the answer is D.
