GutsQLF Posted December 15, 2023 Share Posted December 15, 2023 Bonjour, petite question un peu bête mais pour l'item c du qcm 9 (compté vrai) ça devrait pas plutôt être 2x10 3 vu que 2 gy = 2 J/Kg donc en gramme 2/0,001 = 2x10 3 Quote Link to comment Share on other sites More sharing options...
Solution POMME Posted December 16, 2023 Solution Share Posted December 16, 2023 Salut, pour moi en gros tu as D = E/m donc si tu cherche l’énergie en Joule tu a E = D x m donc E = 2 x 0,001 = 2 x 10^-3. J’espère que c’est plus clair pour toi, sinon n’hésite pas si tu as d’autres questions. GutsQLF 1 Quote Link to comment Share on other sites More sharing options...
