A wire carrying a current of 2.85 A has a straight segment of 2.35 m. Determine the magnitude of the magnetic field due to this segment of wire at a point P which is at the midpoint of the straight segment of wire and a distance of 0.275 m perpendicular to the wire.

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?

Name two kinds of practical electric pumps.
