using a memory size of 40 megabytes. Suppose the cost of a seek is 5milliseconds, while the disk transfer rate is 40 megabytes per second.a. Find the cost of sorting the relation, in seconds, with bb = 1 andwithbb = 100.b. In each case, how many merge passes are required?c. Suppose a flash storage device is used instead of a disk, and it has aseek time of 1 microsecond, and a transfer rate of 40 megabytes persecond. Recompute the cost of sorting the relation, in seconds, withbb = 1 andwith bb = 100, in this setting.
