Express the quantity 556.2 x 10^-12 in each units

A.) ms

B.) ns

C.) ps

D.) fs

The answer:

we should know the meaning of each abbreviation:

ms means millisecond, its value is 10^-3 s

ns means means nanosecond, its value is 10^-9 s

ps means picosecond, its value is 10^-12 s

fs means femtosecond, its value is 1x 10^15 s

Expressions of the quantity 556.2 x 10^-12 are

556.2 x 10^-12 = 556.2 ps

556.2 x 10^-12 = 556.2 x 10^-9 x 10^-3 = 556.2 x 10^-9 ms

556.2 x 10^-12 = 556.2 x 10^-3 x 10^-9 = 556.2 x 10^-3 ns

556.2 x 10^-12 = 556.2 x 10^ - 27 x 10^15 = 556.2 x 10^ - 27 fs
