Awheel of radius 30 cm is rotating at a rate of 2.0 revolutions every 0.080 s. (a) through what angle, in radians, does the wheel rotate in 1.0 s? (b) what is the linear speed of a point on the wheel's rim? (c) what is the wheel's frequency of rotation?

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?
