Answer 5

If x is a vector, then its length determinant of x is a scalar quantity and determinant of a is always non negative.

Answer 6

Yeah, because a scalar is a measure of magnitude, and we do have magnitudes in vectors.

Answer 7

unless you are talking about ZERO vector.. which has only direction but no magnitude.. but its no physical significance whatsoever

So yes.. any vector you consider is basically a a physical quantity with direction..
