Answer:
A unit vector is (D) a vector with a magnitude of one
Explanation:
Unit Vector Information:
A unit vector is a vector with a magnitude of one. Vectors of different magnitudes can be scaled off the unit vector. Also, they can be used in two, three, or more dimensions.
Other Answers:
A. a vector with all three directions or dimensions that are given
This is the definition of a 3D vector. This is a line segment in three-dimensional space running from point A (tail) to point B (head). Each vector has a magnitude (or length) and direction.
B. a vector with only one dimension
This is the definition of an one-dimensional vector. This type of vector has no dimension, but a number of components, therefore it behaves like a real number.
C. a vector that has an x and y components that are equal in magnitude
(Unsure, I believe this would be defined as an equal vector. Correct me if I'm wrong and I will edit it.)
I hope this helps!
