Apendulum that moves through its equilibrium position once every 1.000 s is sometimes called a “seconds pendulum.” what is the period of any seconds pendulum? 1. 4.000 s 2. 2.000 s 3. none of these 4. 1.000 s 5. 0.500 s 6. 0.250 s

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?
