Answer:
491.52 Kb
Explanation:
Number of revolution in a minute (= 60000 milliseconds) = 10000
Number of revolution in 1 millisecond = 1 / 6
So for a half revolution the time required = 3 milliseconds
Data Transfer = 160 X 1024 Kb/1000 s = 163.84 Kb/milliseconds
Data amount = 163.84 X 3 = 491.52 Kb
