The statement is true in this situation is C. The size of Ffric is the same as the size of Fapp:

From the diagram, since the body is in equilibrium, the sum of vertical forces equals zero. Also, the sum of horizontal forces equal zero.

So, ∑Fx = 0 and ∑Fy = 0

Since Fapp acts in the negative x - direction and Ffric acts in the positive x - direction,

∑Fx = -Fapp + Ffric = 0

-Fapp + Ffric = 0

Fapp = Ffric

Also, since Fgrav acts in the negative y - direction and Fnorm acts in the positive y - direction,

∑Fy = Fnorm + (-Fgrav) = 0

Fnorm - Fgrav = 0

Fnorm = Fgrav

So, we see that the size of Fapp <u>equals</u> size of Ffric and the size of Fnorm <u>equals</u> the size of Fgrav.

So, the correct option is C

The statement which is true in this situation is C. The size of Ffric is the same as the size of Fapp.

Not enough air is pumped into an inflatable life raft to make completely filled out the atm pressure is 14.7psi what is the pres
sasho [114]
If you do not inflate the life raft to make completely filled out, as long as you do not press or squeeze  the life raft, the air inside it will be in equilibrium with the air outside the raft, and so the pressure inside the life raft will be the same atmospheric pressure, 14.7 psi.

Note that when the raft is swollen, if you punch it, the air will leave from it which means that the pressure inside is greater than the atmospheric pressure.

which scenario will most likely result in a change to the nitrogen cycle that negatively affects plant growth?
Fed [463]

Soil acidification is a circumstance which will most likely lead to a change in the nutrient cycling that will have a detrimental impact on plant growth.

<h3>What is the main use of nitrogen?</h3>

The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. N must first be combined with hydrogen to create ammonia in order to create these products. The Haber process is used for this. Similar to chlorine gas and carbon monoxide poisoning, nitrous oxide poisoning is detrimental to all living things.

<h3>Why is nitrogen poisonous?</h3>

Effects on health. The majority of greater nitrogen oxides are irritants to the eyes, skin, and respiratory system. Except at deadly quantities, where arginine may kill more quickly, no2 is a corrosive chemical that, when in contact with water, produces nitric and nitrous acids.
