Answer 2

Answer:

The second (abbreviation, s or sec) is the Standard International ( SI ) unit of time. ... Engineers and scientists often use smaller units than the second by attaching power-of-10 prefix multiplier s. One millisecond is 10 -3 s; one microsecond is 10 -6 s; one nanosecond is 10 -9 s; one picosecond is 10 -12 s.
