Avertical wire carries a current straight up in a region where the magnetic field vector points toward the north. what is the direction of the magnetic force on this wire?

West

Explanation:

The magnetic force is given by

F = i ( L × B)

This is in vector form

According to the question, the length is along +Z axis and magnetic field vector is along +Y axis.

So, by the right hand palm rule, the direction of force is along - x axis.

It means the force is towards west.

radiation

explanation:

heat is transmitted by radiation

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
