1. lGiven a = 1'1,le and b = [14.x], solve for variable it so that the magnitude of o + b equals 5. 2. liCSiven the magnitude of vector 0 is 5 and the magnitude of b is 2, and the angle between the vectors is 30 degrees. determine the magnitude and direction of a + 4b 3. A] Explain why the equation o = zrmognitude of b} is not meaningful. B] If two vectors have the same magnitude, then they must be either equal or opposite vectors. True or False, with justification. C) If two vectors are parallel, then thev must be equal or opposite vectors. True or Faise, with justification
