Answer
a) $ 45.3MN$
b) $ 56.8km$
c) $ 5.63 \mu g$
Work Step by Step
We are asked to turn a few quantities to a number between 1 and 1000 using the appropriate prefix.
(a) $45, 320 kN * \frac{1000N}{1kN} *\frac{1MN}{10^6N} =45.3 MN$
(b) $568*10^5 mm *\frac{1m}{1000mm} *\frac{1km}{1000m}= 56.8 km $
(c) $0.00563 mg* \frac{1g}{1000mg} *\frac{10^6\mu g}{1g}= 5.63 \mu g$
