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:

  • F = 8000000 N
  • A = 200 m²

Substitute these values into equation 1

  • P = 8000000/200
  • P = 40000 N/m².

Hence, The pressure of the air is 40000N/m².

Calculate the pH of the following:
Brums [2.3K]

The pH can be defined as the negative logarithm of the hydrogen ion concentration of the solution.

<h3>What is the pH?</h3>

What we call the pH can be defined as the negative logarithm of the hydrogen ion concentration of the solution. We are aware that we can use the relation [H+]  [OH-]  = 1 * 10^-14 to handle the enormity of this problem.

Now, let us go about solving the problems;

1. pH = -log(1 x 10-7) = 7

2.  [H+]=  1 * 10^-14/ 1 x 10^-3

pH =  -log(  1 * 10^-11)

pH = 11

3. pH = -log( 1 x 10^-2)

pH = 2

4. pH = -log(  1 x 10^-10)

pH = 10

5.  [H+]=  1 * 10^-14/ 1 x 10^-8

[H+]=  1 * 10^-6

pH = 6
