Summary[edit]
| Description |
Македонски: Опит со епрувета што плива и тоне. Во епруветата има вода и воздух и е потопена во пластично шише со вода. Кога шишето ќе се притисне, во епруветата навлегува вода, со што се зголемува средната густина на системот епрувета-вода-воздух и поради тоа епруветата тоне. Изведено и објаснето од проф. Оливер Зајков. Институт за физика на Природно-математичкиот факултет во Скопје.
English: Floating and sinking demonstration (Cartesian diver). The tube is filled with water and air. When pressing the bottle, the additional water enters the test tube, thus increasing the average density of the system tube-water-air, resulting with negative buoyancy and the tube sinks. Performed and explained by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Expérience du ludion. Le tube est rempli d'eau et d'air. Lorsqu'une pression est exercée sur la bouteille, de l'eau supplémentaire pénètre dans le tube, ce qui compresse l'air de celui-ci. La masse volumique du tube augmentant, celui-ci coule. Expérience réalisée et expliquée par le professeur Oliver Zajkov de l'Institut de physique de l'université Saints-Cyrille-et-Méthode de Skopje de Macédoine. |
