Answer
a. 5.89 ps
b. 20.1 cm
c. 2.560 ng
d. 6.05 km
Work Step by Step
a. 5.89 x $10^{-12}$ s
$10^{-12}$ is the multiple for pico in SI system. Therefore 5.89 x $10^{-12}$ = 5.89 ps
b. 0.2010 m
Since 1m = $10^{2}$ cm we can write:
0.2010 m x $10^{2}$ cm\1m = 0.2010 x $10^{2}$ cm = 20.1 cm
c. 2.560 x $10^{-9}$ g
In the SI system $10^{-9}$ stands for nano. Therefore
2.560 x $10^{-9}$ g = 2.560 ng
d. 6.05 x $10^{3} $m
In SI system 1km = $10^{3} $ m so we can write:
6.05 x $10^{3} $m = 6.05 km
