Question

How does multiplying a vector by a scalar value of -pi/4 change the vector?
A.) The vector will change direction and increase in magnitude.
B.) The vector will change direction and decrease in magnitude.
C.) The vector will not change direction but will increase in magnitude.
D.) The vector will not change direction but will decrease in magnitude.

Answer 1

same type of question as your next one, only the scalar has changed.

Answer 2

B. The direction will change 180o, and the magnitude will decrease.
I'm assuming you mean -pi/4.
