Answer: 5 × 10^8 cycles per second
Step-by-step 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.
