Karlheinz Brandenburg's work led to the invention of MP3 files. These files are now used to store music and
podcasts on digital devices such as computers and
smartphones
Which want or need was he most likely trying to meet when he developed this
wave technology?

C Away to make music files small enough to share easily over the
Internet
D A way to make museumstruments affordable to more people

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.
