Answer 1

Answer:

unit vectors perpendicular to each other.

Explanation:

I think

Answer 2

Answer:

Given two unit vectors, their cross product has a magnitude of 1 if the two are perpendicular and a magnitude of zero if the two are parallel. The dot product of two unit vectors behaves just oppositely: it is zero when the unit vectors are perpendicular and 1 if the unit vectors are parallel.
