Multiplying a vector by a scalar changes its:
ABeginning
BMagnitude
CDimensions
DCoordinates
Answer & Solution
Correct answer: B. Magnitude
1. The scalar scales the vector's length.
2. The direction stays or reverses only with sign.
3. So the magnitude is multiplied by the scalar's size.
4. The answer is magnitude.
