OC userin Accounting·17 Nov 2017EXERCISE 12-11 Make or Buy a Component (L012-3] Han Products manufactures 30,000 units of part S-6 each year for use on its production line. At this level of activity, the cost per unit for part S-6 is: Direct materials ..................... Direct labor ........................ Variable manufacturing overhead ....... Fixed manufacturing overhead .......... Total cost per part $ 3.60 10.00 2.40 9.00 $25.00 An outside supplier has offered to sell 30,000 units of part S-6 each year to Han Products for $21 per part. If Han Products accepts this offer, the facilities now being used to manufacture part S-6 could be rented to another company at an annual rental of $80,000. However, Han Products has determined that two-thirds of the fixed manufacturing overhead being applied to part S-6 would continue even if part S-6 were purchased from the outside supplier. Required: Prepare computations showing how much profits will increase or decrease if the outside supplier's offer is accepted.

OC userin Physics·14 Nov 20175.58 - A bowling ball weighing 71.2 N (16.0 lb) is attached to the ceiling by a 3.80-m rope. The ball is pulled to one side and released; it then swings back and forth as a pendulum. As the rope swings through the vertical, the speed of the bowling ball is 4.20 m/s. At this instant, what are (a) the acceleration of the bowling ball, in magnitude and direction, and (b) the tension in the rope?
