Answer:
3.6 × 10¹² nanoseconds
Explanation:
Hour is the unit of time. Seconds is the SI unit of time.
Hour and seconds are related as:
1 hour = 60 minutes
1 minute = 60 seconds
So,
1 hour = 60 ×60 seconds = 3600 seconds
Thus,
3600 seconds are in one hour
Also,
1 sec = 10⁹ nanoseconds
Thus,
3600 sec = 3600 × 10⁹ nanoseconds = 3.6 × 10¹² nanoseconds
Thus,
3.6 × 10¹² nanoseconds are in one hour.
