Electric current is the flow of which of the following through a wire?

• electrons
• protons
• neutrons
• protons and electrons

electrons

Explanation: In an electric current only electrons flow since they are attracted to the positive terminal side. Protons do not move along with the electrons instead they are still in place in the nucleus so it does not affect the movement of electric flow.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
