The question here would be what is the volume of the room. The density of air that is given has no use. We simply multiply the dimensions given of the room to determine the volume.
<span>43.0m × 18.0m × 15.0m = 11610m^3 ( 3.28 ft / 1 m)^3 = 4.09 x 10^5 ft^3</span>
The velocity at point B is 10 m/s with a pressure of 262500 Pa
<h3>
Bernoulli equation</h3>
According to the continuity equation:
A₁V₁ = A₂V₂
Where A is the area and V is velocity, ρ = density of water = 1000 kg/m³
Hence:
4(5) = 2(V₂)
V₂ = 10 m/s
Using Bernoulli equation:
The velocity at point B is 10 m/s with a pressure of 262500 Pa

<h2>
Answer:Third</h2>
Explanation:
Newton's third law states that every action force has a equal and opposite reaction force.
Example 1:
Consider yourself hitting a wall with your hand,you are exerting a force on the wall but still you feel hurt because the wall exerts same force on your hand in opposite reaction.
Example 2:
Consider yourself standing on ground.You are exerting force on ground.But how are you able to stand on ground even if your mass is forcing you to go down?The answer is normal reaction force.The ground exerts a force on your feet which makes you to stand still.
