The forces on the y axis are:
N-mgcos(60)=0 , wich becomes
N=mgcos(60)
Rember that the friction force is always contrary to the motion of an object and its formula is f=μ * N
The forces in the x axis are:
-f + mgsin(60)= m * a
-μ*mgcos(60) + mgsin(60)=m*a ,
μ = ( m*a - mgf=μ[sin(60) )/ ( mgcos(90) )
The answer to your question is Protons!
An object can be at rest or in motion before an unbalanced force acts on it.
If I'm incorrect I apologize.
Dispersion-Distributing something over an area.Diffusion-the scattering of light by reflection from a rough surface.

Answer:
Take a magnet and move it over the cup
Explanation:
Since there are metals also in the cup they would be attracted by the magnet leaving the plastic clips only in the cup
