Worth It was an American entertainment web series by BuzzFeed.Starring Steven Lim and Andrew Ilnyckyj, it ran from September 18, 2016 to April 8, 2023. Posted to Hulu and YouTube, each episode of the series compares three different food dishes from three locations that are sold at low, medium, and high price points.
Iridium in bulk metallic form is not biologically important or hazardous to health due to its lack of reactivity with tissues; there are only about 20 parts per trillion of iridium in human tissue. [22] Like most metals, finely divided iridium powder can be hazardous to handle, as it is an irritant and may ignite in air. [66]

Gy = J/kg = kg m 2 /s 2 / kg = m 2 /s 2; S = 1/Ω = 10 −7 s / k A m H = Ω s = 10 7 k A m; Because the magnitude of many of the units composing the SI system of measurement was until 2019 defined by its mass, the quality of the IPK was diligently protected to preserve the integrity of the SI system.
Of course, cost per kg is not the only important factor in material selection. An important concept is 'cost per unit of function'. For example, if the key design objective was the stiffness of a plate of the material, as described in the introductory paragraph above, then the designer would need a material with the optimal combination of ...
Periodic tables usually at least show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights .
In addition, 22,650 kg per cubic meter is inconsistent with the value of 22.42 g·cm−3 given in the tabular summary for iridium. --LexCon 14:17, 8 Nov 2007 (ET) --TrinaLovesInfo 14:05, 7 Dec 2014 (CST) There's a continuing contradiction in the story re. the relative densities of the two elements. They're the ones referenced with 3 and 9.
