Represent each of the following combinations of units in the correct SI form: (a) $\mathrm{kN}/?\mathrm{s}$, (b) $\mathrm{Mg}/\mathrm{mN}$, and (c) $\mathrm{MN}/(\mathrm{kg}?\mathrm{ms})$. 1-3. Represent each of the following combinations of units in the correct SI form: (a) $\mathrm{Mg}/\mathrm{ms}$, (b) $\mathrm{N}/\mathrm{mm}$, (c) $\mathrm{mN}/(\mathrm{kg}??\mathrm{s})$. 1-9. Represent each of the following combinations of units in the correct SI form using an appropriate prefix: (a) $\mathrm{m}/\mathrm{ms}$, (b) $?\mathrm{km}$, (c) $\mathrm{ks}/\mathrm{mg}$, and (d) $\mathrm{km}??\mathrm{N}$. 1-10. Represent each of the following combinations of units in the correct SI form: (a) $\mathrm{GN}??\mathrm{m}$, (b) $\mathrm{kg}/?\mathrm{m}$, (c) $\mathrm{N}/{\mathrm{ks}}^2$, and (d) $\mathrm{kN}/?\mathrm{s}$. 1-11. Represent each of the following with SI units having an appropriate prefix: (a) $8653\mathrm{ms}$, (b) $8368\mathrm{N}$, (c) $0.893\mathrm{kg}$. 1-18. Evaluate each of the following to three significant figures and express each answer in SI units using an appropriate prefix: (a) $354\mathrm{mg}(45\mathrm{km})/(0.0356\mathrm{kN})$, (b) $(0.00453\mathrm{Mg})(201\mathrm{ms})$, (c) $435\mathrm{MN}/23.2\mathrm{mm}$. 1-19. A concrete column has a diameter of $350\mathrm{mm}$ and a length of $2\mathrm{m}$. If the density (mass/volume) of concrete is $2.45\mathrm{Mg}/{\mathrm{m}}^3$, determine the weight of the column in pounds.
