Explanation:
Hey, there!
The liquid pressure varies with depth because liquid pressure is directly proportional to the depth of liquid from the free surface of the liquid. so, more the depth more the pressure and less the depth less the pressure.

The coefficient of static friction of the block is 0.068.
<h3 />
<h3>What is static friction?</h3>
This is the force between two bodies in contact and tends to oppose their motion. It is also the force that keeps two bodies at rest
To calculate the coefficient of static friction, we use the formula below.
Formula:
- F = mgμ............. Equation 1
Where:
- F = Horizontal force
- m = mass of the block
- g = acceleration due to gravity
- μ = coefficient of static friction.
Make μ the subject of the equation
- μ = F/mg.............. Equation 2
From the question,
Given:
- m = 3 kg
- g = 9.8 m/s²
- F = 2 N
Substitute these values into equation 2
- μ = 2/(3×9.8)
- μ = 2/29.4
- μ = 0.068.
Hence, The coefficient of static friction of the block is 0.068.
