Answer 2

a).1 mm /s = 10-3 m/s

Now, 10-12 m/s = 1 pm/s

or, 10-3 m/s = 1/ 10-12 x 10-3 pm/s = 109 pm/s

Hence, 1 mm/s = 109 pm/s

Hence, 1.54 mm/s = 154 x107 pm/s

b). 2.66 gm Cm-3 = 2.66 x 10-6 µgCm-3

Now, 1 cm = 10-2 m = 10-2 x 10-6 µm = 10-8µm

Hence, 2.66 gm Cm-3 = 2.66 x 10-6 / 10-8µgµm-3 = 266 ug µm-3
