Some physics students design an apparatus to measure the weight of objects using a beam and fulcrum pivot. One of the students stands on the apparatus to be weighed. The student, of weight w, stands .30m from end A of the uniform beam AB. The beam has a weight of 80N and length 2.om. A fulcrum pivot at P supports the blank and the downward loads and is .50m from end A. A counterweight of 70N is moved to the position 1.80m to balance the weight of the student and to put the system into rotational equilibrium. Determine the weight w of the student.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

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?
