A199 g oscillator in a vacuum chamber has a frequency of 1.58 hz . when air is admitted, the oscillation decreases to 44.2 % of its initial amplitude in 46.5 s . what is the dampening constant of the oscillation? the answer needs to be in the unit - seconds.

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?
