20.500.12556/RUL-146153 Composition of coin and alloys in 2 euro coin A few years ago, 14 year old students at the Slovenian physics competition were given the experimental task of measuring the composition of two alloys used in 2 euro coins. By performing some simple but as accurate as possible measurements of the density of the coin (and its parts) with simple measuring devices and applying some simple and justified assumptions, a surprisingly good estimate of the composition of the 2 euro coins was obtained. In this paper, we describe the density measurements performed to solve the experimental task and present the basic results of the competition. experimental problem alloy simple measurements physics competition density eksperimentalna naloga sestava dveh zlitin kovanci true false true Angleški jezik Slovenski jezik Članek v reviji 2023-05-22 09:35:26 2023-05-22 09:35:28 2023-05-24 03:40:01 0000-00-00 00:00:00 2023 0 0 8 str. no. 3, art. 035025 Vol. 58 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 373.32.016:53 1361-6552 10.1088/1361-6552/acc5d2 152787971 RAZ_Rovsek_Barbara_2023.pdf RAZ_Rovsek_Barbara_2023.pdf 1 CE45A3E8398E06C46F45DBE7FD64A918 40e9ed6a99b2a85d1d31d6074a4451eef7fbaf2315a9b98b67e2ab980eaac497 c635012c-f873-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169294 https://iopscience.iop.org/article/10.1088/1361-6552/acc5d2 0 0c61d440-f874-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169295 Pedagoška fakulteta 0 0 0
