Answer:
Explanation:
10) II
Vectors are added by putting the tail of the second at the head of the first. The result is the vector from the tail of the first to the head of the second
11) IV
Negating a vector will give it the same magnitude but opposite direction. Then treat as addition as in Q 10
12) B any value between 3 N and 17 N
Magnitude will be 3 when the vectors are co-linear but opposite in direction.
Magnitude will be 17 when the vectors are co-linear and in the same direction.
Magnitudes between 3 and 17 will occur when the vectors are not co-linear
