2. For each of the following, state whether the quantity is a scalar or a vector and give a brief explanation why: height, temperature, weight, mass, area, volume, distance, displacement, speed, force, and velocity.4. Vectors a, b, and c are as shown. a. Construct a + (b + b. Construct ( a + b ) + 7. c. Compare your results from parts a. and b.3. An airplane's direction is E25 N. Explain why this is the same as N65*E or a bearing of 65.3. Redraw the following three vectors and illustrate the associative law. a2. a. Describe in your own words what it means for a point and its associated vector to be uniquely represented in RS. b. Suppose that OP = (a, -3, c) and OP = (-4, b, -8). What are the corresponding values for a, b, and c? Why are we able to be certain that the determined values are correct?1. For A(-1, 3) and B(2, 5), draw a coordinate plane and place the points on the graph. a. Draw vectors AB and BA, and give vectors in component form equivalent to each of these vectors. b. Determine OA and OB c. Calculate AB and state the value of BA .PART A 1. a. Write the vector OA = (-1, 2, 4) using the standard unit vectors. b. Determine OA .2. It is claimed that {(1, 0, 0), (0, 1, 0), (0, 0, 0) } is a set of vectors spanning R". Explain why it is not possible for these vectors to span R"
