The filament in an incandescent light bulb is made from tungsten metal (rho = 19.3 g/cm3) 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 m length of tungsten wire weighs 42.9 mg, then what is the diameter of the wire? express your answer in millimetres.
