What is the Physics Primer?

(A) A set of mathematics topics that are relevant to introductory physics courses.
(B) A list of the most important formulas used in introductory physics courses.
(C) An detailed explanation of all of the mathematics you will use in your introcuctory physics course.
(D) A tutorial of the most important physics concepts covered in introductory physics courses

A is the correct option.

Explanation:

Physics primer is a set of mathematics topics that are relevant to introductory physics courses. The idea behind the physics primer is to provide the students a strong base of mathematics concept that can be helpful for them in the future courses of physics. It should be taken before the introductory lessons of physics. It will help out students in solving those physics problems that involves mathematics. Physics primer is usually comprised of tutorials, answers of specific questions and videos.

well, their are quite a few differences !

explanation:

first difference is a main sequence star is made of carbon, while a neutron star is made of neutrons. another difference is a main sequence star still has hydrogen to burn, while a neutron star is a remnant of a supernova.

a main sequence star is what’s left over from a low-mass star death, while a neutron star is what’s left from the death of a high-mass star. main sequence star and a neutron star are considered the same thing, except a main sequence star spins.
