Advd has a diameter of 120 mm. placed into a dvd player it has a maximum angular velocity of 1530 rpm. a. if it takes 1.7 s to reach maximum velocity from a resting position, what is the total b. if a 1 g bead is anchored to the edge of the disc, what is the centripetal force on the c. when powered down, it takes 7.6 s to come to a complete stop. what is the value of d. what is the angular deceleration? angular acceleration? bead? mechanical friction from the disc player?

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
