Question

Which of these time measurements is the smallest?
0.02 seconds
0.02 teraseconds
2,500 milliseconds
25,000 nanoseconds

Answer 1

25,000 nanoseconds is the smallest.

Conversions to seconds:
- 0.02 s = 0.02 s
- 0.02 teraseconds = 0.02 × 10^12 s = 2.0 × 10^10 s
- 2,500 milliseconds = 2,500 × 10^-3 s = 2.5 s
- 25,000 nanoseconds = 25,000 × 10^-9 s = 2.5 × 10^-5 s

2.5 × 10^-5 s is the smallest.
