Find the scalar and vector projections of b onto a. a = i+j+k, b= i- j+k compab = projab = (smaller i-value) > (larger i-value)A wrench 30 cm long lies along the positive y-axis and grips a bolt at the origin. A force is applied in the direction (0, 3, -4) at the end of the wrench. Find the magnitude of the force needed to supply 150 N . m of torque to the bolt. (Round your answer to the nearest whole number.) NFind the volume of the parallelepiped determined by the vectors a, b, and c. a =itj-k, b=i-j+k, c=-i+j+k 6 XFind the work done by a force F = 61 - 4j + 7k that moves an object from the point (0, 6, 4) to the point (2, 16, 20) along a straight line. The distance is measured in meters and the force in newtons
