Answer: Carbon Dioxide
Explanation: Soil aeration is the process that provides the air to the plants and maintains the flow of oxygen and carbon dioxide gases. These are the two most vital gases for the life process of the soil to provide it to the plants and other micro organisms. It provides these gases so that there can be production in the plant through soil.
Answer:
cos 90° = 0, because the angles are complements
Explanation:
Complementary angles are those angles whose angles are sum up to 90 degrees that we called right angles
Just like
one angle is 45 degrees
And, the other angles are also 45 degrees
So, the sum of both two angles are 90 degrees
Now if
sin 0° = 0
The cos 0° = 0 as the angles are considered to be the complement
We used the equation as shown below:
![sin{\theta} = cos (90 - {\theta})](https://tex.z-dn.net/?f=sin%7B%5Ctheta%7D%20%3D%20cos%20%2890%20-%20%7B%5Ctheta%7D%29)
The process is called desalination, and it is being used more and more around the world to provide people with needed freshwater. ... In some areas, salt water (from the ocean, for instance) is being turned into freshwater for drinking.
