Velocity can be defined as the speed at which an object travels while- F moving in a circular path.
G accelerating by a specific amount.
H moving in a certain direction.
J under a frictional force.

H moving in a certain direction

Explanation:

The velocity of a body can be defined as the speed at which an object travels while moving in a certain direction.

The physical quantity velocity is a vector which has magnitude and directional attributes.

When denoting the velocity of a body, we pay special attention to the direction.

The direction distinguishes velocity from speed

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
