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.

Match each object to its description: a. coma of a comet b. comet tail c. oort cloud haze surrounding a nucleus created by solar wind. hypothetical sphere around the solar system

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
