The pressure of the air is 40000N/m².
To calculate the pressure of the plane, we use the formula below.
Formula:
- P = F/A................. Equation 1
Where:
- P = Pressure of the air
- F = Force on the plane
- A = Total surface area of the plane.
From the question,
Given:
Substitute these values into equation 1
- P = 8000000/200
- P = 40000 N/m².
Hence, The pressure of the air is 40000N/m².

C. air, fire, water, earth. 4 elements
So here we are given that the the velocity of the proton ( V ) is 2.0 × 
meters / second, with a magnetic field of strength 5.5 × 
tesla. If they each form a right angle, they are hence perpendicular to one another, such that ....
F = q( V × B ),
F = q v B( sin ∅ ),
F = q v B( sin( 90 ) )
.... they form the following formula. Let's go through each of the variables in our formula here -
{ F = Magnetic Force ( which has to be calculated ), q = charge of proton (has charge of 1.602 × 
coulombs ), B = magnetic field }
All we have to do now is plug and chug,
F = ( 1.602 × )( 2.0 × )( 5.5 × ) = ( About ) 1.8 ×

Answer:
28g
Solution. Hence, 2 moles of nitrogen atoms weigh 28g.
Fluoride is an anion of Fluorine
What this means is that the two have the same number of protons (9), but Fluoride has 10 electrons compared to Fluorine's 9.
So the answers are:
Protons - 9
Neutrons - 9
Electrons - 10
Atomic Number - 9
Atomic Mass - 19 g/mol
