<span>When an electromagnetic wave passes from space to matter, some part of the energy is absorbed by the matter and it increases its energy. The wave may reflect and some part may pass through the matter depending on the amount of energy they have. The amplitude of the wave decreases if some parts of it are reflected. </span>
All of the above,
because Water pollution comes heavily from sewage and agricultural runoff, and comes from the rust and materials from heavy metals.

Explanation:
Well, kinetic energy is expressed through the equation:
KE
=
1
2
m
v
2
m
is the mass of the object in kilograms
v
is the velocity of the object in meters per second
So, we plug in the values, which are
m
=
0.02
kg
v
=
300
m/s
And we get,
KE
=

A molecule of the compound carbon dioxide contains one atom of the element carbon and two atoms of the element oxygen. Each oxygen atom shares a double bond with the carbon atom.
The chemical formula of the molecule of sodium carbonate is Na2CO3. Atom is the smallest particle of a chemical element that can exist. Na2CO3 is made of three atoms of oxygen.This because Na2CO3 has subscribe three just after the oxygen
