Answer:

<em>An element is the material that cannot be broken down further by chemical means.</em>

Explanation:

An element can be described as a material which is made up of only one kind of atom. For example, argon, hydrogen etc. An element cannot be broken down further by physical or chemical means.

Compounds, on the other hand, are made of different kinds of atoms. They can be broken down to simpler molecules by chemical means. For example, water is a compound made up of hydrogen and oxygen.

If the separation between two charges increases, how does the force

Leona [35]

The force reduces

Explanation:

According to Coulomb's law, the force between the charges will reduce if the separation between the charges increases.

Coulomb's law states that "the force between two charges is a directly proportional to the product of the magnitude of the charges and inversely proportional to the square of their separation.".

F = $\frac{K q_{1} q_{2} }{r^{2} }$

where F is the electric field force

K is the constant of the field

$q_{1}$ is charge 1

$q_{2}$ is charge 2

r is the separation

We see that the separation is inversely proportional to the force between the charges. The larger the separation, the weaker or smaller the force.
