Ocecrf Posted November 22, 2020 Posted November 22, 2020 Bonjour j’aurai besoin de votre aide pour ce QCM s’il vous plait je ne comprend pas comment faire le D et E Quote
Solution SetiaHatiTerate Posted November 22, 2020 Solution Posted November 22, 2020 Salut, Il faut utiliser la formule suivante: Mz,90° (t) = (1-e^[-t/T1]) . M0 <=> Mz,90° (t) / M0 = 1 - e^(-t/T1) = 1 - e^(- 140 / 700) = 1 - 0,82 = 0,18 <=> 18% => D est vrai Quote
