Answer

a) $15.9mm/s$ b) $3.69 Mm * s/kg$ c) $1.14 km * kg$

Work Step by Step

We are given a few quantities and asked to convert and evaluate them using appropriate prefixes. a) $(684 \mu m)/(43 ms)* \frac{10^3ms}{1s} * \frac{1m}{10^6 \mu m}* \frac{1000mm}{1m}=15.9mm/s$ b) $(28 ms)(0.0458 Mm)/(348 mg) * \frac{1s}{1000ms}* \frac{10^3mg}{1g}* \frac{10^3g}{1kg}=3.69 Mm * s/kg$ c) $(2.68 mm)(426 Mg) * \frac{1m}{10^3mm}* \frac{1km}{10^3m}* \frac{10^6g}{1Mg}* \frac{1kg}{10^3g}=1.14 km * kg$
