The filament in an incandescent light bulb is made from tungsten metal \(\left(d=19.3 \mathrm{g} / \mathrm{cm}^{3}\right)\) that has been drawn into a very thin wire. The diameter of the wire is difficult to measure directly, so it is sometimes estimated by measuring the mass of a fixed length of wire. If a \(0.200 \mathrm{m}\) length of tungsten wire weighs \(42.9 \mathrm{mg}\), then what is the diameter of the wire? Express your answer in millimeters.
The volume of a red blood cell is about $90.0 \times 10^{-12} \mathrm{cm}^{3} .$ Assuming that red blood cells are spherical, what is the diameter of a red blood cell in millimeters?
Calculate the mass of a cylinder of stainless steel \(\left(d=7.75 \mathrm{g} / \mathrm{cm}^{3}\right)\) with a height of \(18.35 \mathrm{cm}\) and a radius of \(1.88 \mathrm{cm}\).
Which is the greater mass, \(3245 \mu \mathrm{g}\) or \(0.00515 \mathrm{mg} ?\) Explain.
