If a machine cycle is 2 nanoseconds , how many machine cycles occur each second?

5 × 10^8 cycles per second

Explanation:

First and foremost, we should note that 1 nanosecond = 1 × 10^-9 seconds

We are told that the machine cycle is 2 nanoseconds.

The number of machine cycles that occur each second will them be calculated as:

1 = 2 × 10^-9

= 5 × 10^8 cycles per second

The number of machine cycles that occur each second is 5 × 10^8 cycles per second.
