One of the methods that are used to separate polymers, aluminium alloys, and steels from one another is the Gravitation Separation method.
One straightforward technique is to run the mixture through a magnet, which will keep the steel particles on the magnet and separate them from the polymer.
What is the Gravitation Separation method?
When it is practicable to separate two components using gravity, i.e., when the combination's constituent parts have different specific weights, gravity separation is a technique used in industry. The components can be in suspension or in a dry granular mixture.
Polymers, Steel and Aluminium alloys can be readily split apart. The technique depends on how the two components are combined. The approach used is gravitational density. Due to the significant difference in relative specific mass values between steel and polymers (which range from 1.0 to 1.5), it is possible to separate them using flotation in a liquid that is safe and has the right density.
Therefore, the Gravitation Separation method is used to separate polymers, aluminium alloys and steels.

Answer:
x=2.19in
Explanation:
This is the equation that relates the force and displacement of a spring
F=Kx
m=mass=12.5lbx1slug/32.14lb=0.39slug
F=mg=0.39*32.2=12.52Lbf
then we calculate the spring count in lbf / ft
K=F/x
K=5.7lbf/1in=5.7lbf/in=68.4lbf/ft
Finally we calculate the displacement with the initial equation
X=F/k
x=12.52/68.4=0.18ft=2.19in
Answer:
depends on the size
Explanation:
Length x width x depth x 7.5 = volume (in gallons)
Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool, expressed in gallons.
