Bonjour,

1 m
1 dm = 10^-1 m

1 cm = 10^-2 m

1 mm = 10^-3 m

1 µm = 10^-6 m

1 nm = 10^-9m

a) 10^-3 A = 1 mA

Vrai

b) 10^-9 g = 10 ng

Faux, 10^-9 g = 1 ng

c) 10^-2 m = 1 dm

Faux, 10^-2 m = 1 cm

d) 10^-6 m = 1 mm

Faux, 10^-6 m = 1 µm

e) 7 x 10^-6 m = 7 µm

Vrai

Selon toi, la f est-elle vraie ou fausse ?
