Why is it necessary to use a solid agar medium to obtain a pure culture of S. epidermidis?

It is not a rule that it is done always this way. However, the sample you take is from the skin and it is going to be mixed with many other bacteria types. Using an agar plate and proper techniques, you can easily separate it from the others.

What are advantages of a solid?
The culture on solid media (agar) surface aids microbiologist in identifying microorganism because individual species often from colonies of characteristic size and appearance. When mixed population has been plated properly, it sometimes is possible to identify the desired colony based on its overall appearance and use it to obtain a pure culture. Whereas in liquid broth we get mixed culture and can not identify the seprate colony of any microbial species in that mixed culture.

What is the value of petri plates in microbiology?
It gives microbiologists a way to grow bacteria on a solid medium. This is important if you want to be able to obtain a pure culture, without a solid medium to grow bacteria it would be nearly impossible. On a solid media a single colony can be isolated and used to innoculate a further plate or broth culture. All the bacteria present in a colony should be decendents of a single organism and so be genetically identical. To obtain a pure culture in liquid media, you would have to do numerous serial dilutions which is very labor intensive compared to streaking a solid medium. Even after many serial dilutions there would be no way to ensure a pure culture.
Describe the methods that you can use to obtain a pure culture and state the significance?
A pure culture is usually derived from a mixed culture (one containing many species) by transferring a small sample into new, sterile growth medium in such a manner as to disperse the individual cells across the medium surface or by thinning the sample manyfold before inoculating the new medium. Both methods separate the individual cells so that, when they multiply, each will form a discrete colony, which may then be used to inoculate more medium, with the assurance that only one type of organism will be present

How does an author obtain copyright?
Initially copyright protection is instantaneous as soon as the author has fixed his/her story in a "tangible medium". If formal registration is deemed necessary the author, or his/her agent will have to contact the Copyright Office in their area for instructions.

Why media culture is specifically?
Culture media should be specific to avoid contamination of unwanted microorganisms and to obtain a pure culture of microorganisms.
