alleryThe magnitude of a scaled vector equals the original magnitude times the scalar's:
ALogarithm of it
BAbsolute value
CSquare of it
DReciprocal of it
Answer & Solution
Correct answer: B. Absolute value
1. The length is scaled by the size of the multiplier.
2. The sign of the multiplier affects only the direction.
3. So the magnitude is multiplied by the absolute value.
