The coefficient of kinetic friction (μ) between the block and the table is 0.4.
<h3>
What is kinetic friction?</h3>
This sis the frictional force between an object in motion with the surface in contact.
μN = ff
where;
- N is normal reaction due to weight of the block
- ff is frictional force
- μ is coefficient of friction
μ = ff/N
μ = 8/20
μ = 0.4
Thus, the coefficient of kinetic friction (μ) between the block and the table is 0.4.

Answer:
0.025 m
Explanation:
From the question,
Applying Hook's law
F = ke................... Equation 1
Where F = Force, k = spring constant of the scale, e = maximum distance at which the spring will compress.
make e the subject of the equation
e = F/k....................... Equation 2
Given: F = 10 N, e = 395 N/m
Substitute these values into equation 2
e = 10/395
e = 0.025 m
The correct answer would be True!
