1. The number of significant digits in the product of 54.6 X 342.8 is a) 3 b) 4 c) 5 d) 7 A millimeter is a) 0.01 m b ) 0.001 m c) 100 m d) 1000 m 3. Which one of the following figures represent Ã, +Ã, +ă,? (b) (c) (d) (e) ___4. Given vectors A and B as shown in Figure, which vector shows 2A - B (a) (b) () (d) (e) PART B (12 Pts): Show your work clearly and completely for full credit. (Use the back of the sheet if necessary). Let A = (3.0m, 20° South of east), B = (2.0 m North) and C=(5.0 m , 70° South of west). (Bold letters indicate vectors) a) Draw and label A, B and C with their tails at the origin. Use a coordinate system with the x axis to the east b) Write A, B and C in component form, using unit vectors c) Find the magnitude and direction of D=A+B+C
