Magnetism is a non contact force. This is brcause magnetism “acts on an object without being in physical contact with it”
The density of a plasma can be described as : ( A ) Low density
<h3><u>Density </u></h3>
Density is the mass per unit volume of a substance, it is used for comparison between substances because the mass and volume which are scalar quantities of substances are applied.
The density of plasmas are low when compared to solids because the volume occupied by a plasma of the same mass as a solid, is greater when compared to the volume occupied by a solid.
Hence we can conclude that The density of a plasma can be described as Low density.

Answer:
I think this is it.
Explanation:
As all the mass of other molecules are given and we have to find the mass of hydrogen so total subtracted by carbon and oxygen.
Answer:
Cross-pollination
Explanation:
This technique is used to create new varieties, usually with stronger characteristics than the two original varieties. When the pollen of <u>one variety</u> is placed to a <u>different plant's stigma</u>, the resulting seeds create a new variety. This cross-pollination is used in plants of the same species.
Your answer would be D friction.
