@Ilyana31 bonsoir

Attention tu as fait des erreurs de conversion !!!

- 60 battements/min = 1 batt/s   (t'imagines avoir 3600 battement/s ?!?!)

- A = 3 cm2 = 3.10-4 m2 (car on est dans du carré, donc 1 cm2 = 1.(10-2)2 m2)

- ΔV = Q . Δt

        = A.v.Δt

        = 3.10-4 x 1 x 1

        = 3.10-4 m3
