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.

The correct answer is the statement in option 3. Chemical equilibrium is achieved when both the reactants and the products are in concentrations that has no further tendency to change even as time goes to infinity. This happens when the forward reaction rate is the same as the reverse reaction rate.
Answer:
it gains energy in a quantized amount
Explanation:
when we describe the energy of a particle as a quantized ,we mean that only certain values of energy are allowed....it can only gain the exact amount of energy needed to reach one of the higher energy levels
hope this helps :)
