Comparison of conductivity of tap water, salt water, and mercury
Normal water without salts has no carriers of electricity.
Salted water has ionic conductivity, because of the dissociation (disintegration) of the salt molecules into positive and negative ions, such conductivity is second nature.
Well, mercury refers to metals that have free electrons.

Electrostatic painting
The working principle is based on Coulomb's law: in the spraying process, the paint material comes into contact with an electrode which is located on the paint atomizer.

A parachutist and a raindrop
An increase in the drag force as velocity increases results in a steady, uniform motion of a body as it falls from a great height in a liquid or gas (e.g. in the atmosphere).
Thus, a parachutist before opening the parachute can gain speed of only up to 50 m/s, and rain drops, depending on their size, reach speeds from 2 to 7 m/s.
