1 Comment se nomme l'appareil qui permet de mesurer l'intensité d'un courant ?
2. Quelle est la couleur de
la zone où doit se trouver
le sélecteur pour que
le multimètre puisse mesu-
rer une intensité ?
3. L'appareil se branche-t-il
en dérivation ou en série
dans le circuit ?
4. On désire mesurer préci-
sément l'intensité du cou-
rant traversant une lampe.
Sachant que cette intensité
est de l'ordre de 100 mA,
sur quelles bornes doit-on
effectuer les branchements ?
Quel calibre doit-on alors
utiliser ?

An uncharged nonconductive hollow sphere of radius 18.0 cm surrounds a 12.0 µc charge located at the origin of a cartesian coordinate system. a drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. calculate the electric flux through the hole.

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
