Can one say a body which has the conditions above mentioned be in thermal equilibrium? How does one apply the definition of temperature equilibrium to this situation?
(Physically I think it's possible for a body to be in this situation if some part of it receives heat from the outside and...
Yes.
Of course. I studied it in high school. This geometry course is a university level course. I don't think I'll be exposed to a lot of new concepts; I suppose it will be a proof-based course.
I didn't explain myself. I haven't yet taken Linear Algebra I but I will have when I eventually take Linear Algebra II. The course that I have to pick I will only take it six months from now.
Which course is more important to a physics major? Which is more likely to improve one's mathematical ability? Which is more interesting? (I haven't even had Linear Algebra I so I don't know if I like the subject.). Unfortunately, I have to decide now.
