If perfectly elastic there would be no energy left over for exciting the atom. if the collision were partially elastic, then some of the initial kinetic energy would be converted into internal energy,
hope this help
The question is incomplete. The complete question is :
The pressure difference, Δp, ac
ross a partial blockage in an artery (called a stenosis) is approximated by the equation :
Where V is the blood velocity, μ the blood viscosity {FT/L2}, ρ the blood density {M/L3}, D the artery diameter, 
the area of the unobstructed artery, and A1 the area of the stenosis. Determine the dimensions of the constants 
and . Would this equation be valid in any system of units?
Solution :
From the dimension homogeneity, we require :
Here, x means dimension of x. i.e.
![$[ML^{-1}T^{-2}]=\frac{[K_v][ML^{-1}T^{-1}][LT^{-1}]}{[L]}+[K_u][1][ML^{-3}][L^2T^{-2}]$](https://tex.z-dn.net/?f=%24%5BML%5E%7B-1%7DT%5E%7B-2%7D%5D%3D%5Cfrac%7B%5BK_v%5D%5BML%5E%7B-1%7DT%5E%7B-1%7D%5D%5BLT%5E%7B-1%7D%5D%7D%7B%5BL%5D%7D%2B%5BK_u%5D%5B1%5D%5BML%5E%7B-3%7D%5D%5BL%5E2T%5E%7B-2%7D%5D%24)
![$=[K_v][ML^{-1}T^{-2}]+[K_u][ML^{-1}T^{-2}]$](https://tex.z-dn.net/?f=%24%3D%5BK_v%5D%5BML%5E%7B-1%7DT%5E%7B-2%7D%5D%2B%5BK_u%5D%5BML%5E%7B-1%7DT%5E%7B-2%7D%5D%24)
So, ![$[K_u]=[K_v]=[1 ]=$](https://tex.z-dn.net/?f=%24%5BK_u%5D%3D%5BK_v%5D%3D%5B1%20%5D%3D%24)
dimensionless
So, and are dimensionless constants.
This equation will be working in any system of units. The constants and will be different for different system of units.

Answer:
There are 5 main conditions of the alveoli for proper gaseous exchange to in the lungs.
Explanation
Alveoli is found in the lungs of mammals, birds and reptiles. It is the part of the lungs where gaseous exchange really occurs.
Alveoli has a shape of that of balloon but indeed smaller than the real balloon. It allows the passage of oxygen and carbon dioxide
The five main conditions includes:
- The Alveoli must have large surface to volume ratio which increase the gases that could be exchanged
- The wall must be thin. This can shorten diffusion distance.
- Alveoli must be very moist so that oxygen and carbon dioxide can pass through the solution
- Alveoli must be well supplied with blood
- Alveoli must be permeable
A. Balloons can be filled with air.
C. Air has mass.
