The force on the layer will be equivalent to the weight of water on it. This is given by:
F = mg; m is the mass of water and g is the acceleration due to gravity.
Using Newton's Second Law, F = ma, where F is the net force
So the net force is:
F = (6kg)(4m/s^2) = 24N
Since you are applying a horizontal force of 30N, we can find the force of friction by the difference of the net force and the applied force.
30N-24N = 6N
In 0.25h it will move in 22.5 kilometers.
They both have currents that don't change in the beginning
The Coulomb's law equation is F = Kq₁q₂/r².
<h3>
What is Coulomb's law?</h3>
This is the law that relates the product of two charges to the square of distance between the two charges.
Coulomb's law states that the force of attraction or repulsion is directly proportional to the product of the charges and inversely proportional to the square of distance between the charges.
<h3>Coulombs' law equation</h3>
The equation of Coulomb's law is given as;
F = Kq₁q₂/r²
where;
- K is Coulomb's constant, Nm²/C²
- q₁ is the first charge, C
- q₂ is the second charge, C)
- r is the distance between the charges, m
Thus, the Coulomb's law equation is F = Kq₁q₂/r².
