Answer:
it is magnetic force
Explanation:
Magnetic force is the best force when there are different sized forces from opposite direction acting on an o jet it only work when the object is metal like iron nail,aluminium etc
The physical property that is in use when substances are separated using a screen is differences in particle size of the substances.
<h3>What are physical properties?</h3>
The term "physical properties " refers to those properties that are not studied by changing the composition of the substance. Most separation methods depend on differences in physical properties.

Calcium Carbonate Hexahydrate
(Ca C O3 6H20)
The number you would write before water in the formula for calcium carbonate hexahydrate would be 6.
Facts about Calcium Carbonate Hexahydrate:
<span>This compound often crystallises when Essex river waters are softened by the lime/soda process. Formation of the hydrated salt is favoured by low water temperatures and by high orthophosphate levels. Calcium carbonate hexahydrate forms pure well-defined crystals which are considerably more soluble in water than calcite, the usual product of lime/soda softening. </span>

<h3 /><h3>What is aprotic solvent?</h3>
A polar solvent without an acidic proton is known as a polar aprotic solvent. These solvents don't include hydroxyl or amine groups. These solvents can act as proton acceptors, but unlike protic solvents, they do not act as proton donors in hydrogen bonding.
After being exposed to a strong aqueous acidic media and being heated, N-methyl-2-pyrrolidone opens up, forming a molecule with a carboxylic group at one end and a protonated nitrogen atom with a methyl group connected to it at the other.
Alcohol, water, hydrogen fluoride, formic acid, acetic acid, ammonia, methanol, ethanol, and other well-known substances are a few examples of polar protic solvents. Polar aprotic solvents, on the other hand, lack acidic protons and do not function as donors during hydrogen bonding.
