The unit vector is a vector whose magnitude is 1.
Yes, true
No, it's a scalar measurement because it has magnitude only. A vector measurement has both a magnitude and a direction.
NULL VECTOR::::null vector is avector of zero magnitude and arbitrary direction the sum of a vector and its negative vector is a null vector...
