<span>So what happens when there is more than one force? I like to think of net force as if two people were pulling on ropes attached to a big crate. If they pull the crate in the same direction, the crate will accelerate twice as quickly. If they pull in opposite directions with equal forces, the crate won’t move at all — these two forces cancel each other out. If one person pulls northwards and the other pulls eastwards, the crate will move to the north-east.

Answer:
Believe it or not our the light we see "visible light" is an example of electromagnetic wave. other examples include microwaves, radio waves, infrared, ultraviolet, x-rays, and gamma rays.
Explanation:
<span>you have to find the differences of electronegativity for the atoms joined by the bond. if their diff is <0.4,
then it's non-polar
if it's between 0.4 to 1.7
then it's polar
1.7 and up it's ionic
Electronegativity values can be found on most periodic tables.</span>
D is your answer. nearly everything has atoms so it cant be that
