Answer:
A _______________ is a diagram that shows the relationship of one variable to another.
Explanation:
Answer:
Whether the force exerted by the locomotive on the wall was larger
Than the force the locomotive could exert on the wall.
Explanation:
The Newton's third law of motion States that every force have it's equal and opposite reaction force, whose magnitude is the same as the applied force. Therefore the magnitude of these opposite forces will be equal.
So we have;
F12=-F21
F12 is the force in a direction
-F21 is the force in the opposite direction.
Therefore we see that the magnitude of the force the locomotive exerts on the wall is equal to the one the wall exerts on the locomotive. Both magnitudes are equal but in opposite directions.
organisms and water
Explanation:
Organisms and water contribute to both chemical and mechanical weathering . A form of weathering known as biological weathering is a derivative of both chemical and physical weathering.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Organisms are pivotal to both physical disintegration of rocks through their activities.
- Through their metabolic activities, they also releases chemicals that are used for chemical weathering of rocks.
Water is essential for weathering. It is used in alternate freezing and thawing, a mechanical weathering process to break down rocks.
It is used in rock hydrolysis for chemical weathering.

Answer:
In a nutshell, units of A and B are ![\frac{1}{[l]^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Bl%5D%5E%7B2%7D%7D)
and ![\frac{[l]}{[t]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bl%5D%7D%7B%5Bt%5D%7D)
, respectively.
Explanation:
From Dimensional Analysis we understand that 
and 
have length units (![[l]](https://tex.z-dn.net/?f=%5Bl%5D)
) and 
have time units (![[t]](https://tex.z-dn.net/?f=%5Bt%5D)
). Then, we get that:
![[l] = A\cdot [l]^{3}](https://tex.z-dn.net/?f=%5Bl%5D%20%3D%20A%5Ccdot%20%5Bl%5D%5E%7B3%7D)
(Eq. 1)
![[l] = B\cdot [t]](https://tex.z-dn.net/?f=%5Bl%5D%20%3D%20B%5Ccdot%20%5Bt%5D)
(Eq. 2)
Now we finally clear each constant:
![A = \frac{[l]}{[l]^{3}}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B%5Bl%5D%7D%7B%5Bl%5D%5E%7B3%7D%7D)
![A = \frac{1}{[l]^{2}}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B%5Bl%5D%5E%7B2%7D%7D)
![B = \frac{[l]}{[t]}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Bl%5D%7D%7B%5Bt%5D%7D)
In a nutshell, units of A and B are and , respectively.
