This is my physics lab worksheet. I'm not sure if I did 1(a),

Questions1. Two vectors F, and F, are shown in the figure.F.F ,(a) Use the "Parallelogram Method" shown in Fig. 2a draw the resultant vector of F, - F .Hint: Vector subtraction ( F, - F2 ) is a special case of vector addition, since F - F2 = F, + (-F2).(b) Use the "Triangle (head to tail) Method" shown in Fig. 2b draw the resultant vector of F, - F2 .Fz2. What is the difference between scalar and vector quantities?Scalar quantities are only specified bymagnitude.Vector quantities are specified by magnitudeand direction3. Is it always the true that 1 + 2 = 3 ? If not, under what condition 1 + 2 = 3?noisnot alartrue
