Weathering breaks down rock and other material
The laws of the electrostatics were developed by Coulomb and are further detailed or subdivided into two as follows:
(1) The first one talks about the similarities in the charges of the particles and what happens to them. This states that like charges repel.
(2) The second one quantifies the field between two particles with equation showing that field is directly proportional to the masses and inversely to the square of the distance between them.
In this item, we can then say that the protons (having the same charges) will have to repel from each other in accordance to statement 1 of the law.
Answer:
bcoz iron displaces copper and form the solution iron sulfide
Explanation:
when we dip iron nail in copper sulfate solution,then iron starts reacting with the solution and due to displacement reaction between them iron is stronger metal than copper so it displaces copper and form iron sulfide:
CuSO4+3Fe---->Fe3SO4+Cu
