L’Adri\u00e0 Pico va construir durant el confinament un Generador de Van de Graaff i durant la Setmana de la Ci\u00e8ncia ens l’ha portat per acabar-lo d’afinar i ensenyar-lo als companys. Ha utilitzat entre altres coses, un motor de rentadora que va anar a buscar a la deixalleria, una cinta de neopr\u00e8 o un esfera met\u00e0l\u00b7lica buida de dins que s’utilitza en decoraci\u00f3 de jardins.<\/p>\n
Un generador de Van de Graaff<\/b> \u00e9s un generador electrost\u00e0tic que utilitza una cinta m\u00f2bil per a acumular grans quantitats de c\u00e0rrega el\u00e8ctrica a l’interior d’una esfera met\u00e0l\u00b7lica buida. Va ser inventada el 1929 pel f\u00edsic nord-americ\u00e0 Robert J. Van de Graaff. Les diferents aplicacions d’aquesta m\u00e0quina inclouen la producci\u00f3 de rajos X, l’esterilitzaci\u00f3 d’aliments i experiments de f\u00edsica de part\u00edcules i f\u00edsica nuclear.<\/p>\n
Felicitats Adri\u00e0 per la iniciativa i segur que l’acabarem d’afinar.<\/p>\n","protected":false},"excerpt":{"rendered":"
