When you start your computer, the hard disk begins to spin. It takes [Number 6.35] seconds of constant angular acceleration to reach full speed, at which time the computer can begin to access it. If you wanted the disk drive to reach full speed in only [Number 3.34] seconds, the disk drive's motor would have to exert more torque on it during the starting process. Compare the second torque to the original torque.

    Topic: Motion with Constant Angular Acceleration. 19.) When you switch on a PC computer, the disk in the disk drive takes 5.0 s to reach its final steady speed of 7200 rev/min. What is the average angular acceleration? 20.) When you turn off the motor, a phonograph turntable initially rotating at 33 1/3 rev/min makes 25 revolutions before it stops. Calculate the angular deceleration of this turntable; assume it is constant.

    Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
