What are the properties related to vector operations?
a) Maximum and minimum resultant
b) Sum and difference of vectors
c) Multiplication of a vector by a scalar
d) Law of sines
I. The maximum resultant occurs when two vectors form an angle of 0° between them.
II. The minimum resultant occurs when two vectors form an angle of 180° between them.
III. If two vectors are perpendicular to each other, their difference is equal to their sum.
IV. The direction of a vector does not change when multiplied by a scalar.
a) I and II are correct.
b) III and IV are correct.
c) I, II, and III are correct.
d) II, III, and IV are correct.
