Solution ilhamoxiciIline Posted March 19 Solution Share Posted March 19 Salut, tu sais que t 1/2 = ln2/k et pour avoir t 1/10 tu fais 5 x t 1/2 (car 1/2 = 5 x 1/10) donc, t 1/10 = 5 x ln2/k = ln10/k (car 5ln2 = ln10) j'espère que c'est plus clair pour toi Quote Link to comment Share on other sites More sharing options...
