Inhalation is the process of taking air into the lungs. For this to occur, the air pressure inside the lungs must be lower than that of the external atmosphere as air flows from areas of higher pressure to lower pressure. <span>Exhalation is the process of expelling air out of the lungs. For this to occur, the air pressure inside the lungs must be higher than that of the external atmosphere as air flows from areas of higher pressure to ones of lower pressure.</span>
Where are the statements?
Answer:
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
Explanation:
The percentage composition of a given compound is defined as the ratio of the amount of each element to the total amount of individual elements present in the compound multiplied by 100
![\frac{15.1}{43.4} \times 100\%](https://tex.z-dn.net/?f=%20%5Cfrac%7B15.1%7D%7B43.4%7D%20%20%5Ctimes%20100%5C%25)
= 34.79 %
First of all, lets get our equation for Kinetic Energy (KE).
KE = 1/2 (mass) (speed)2
<span>Now, replace the words by adding the actual values. </span>
KE = 1/2(2 kg) x (45 m/s)^2
KE = 2025 J
Answer: Kinetic energy = 2025 Joules
