Wave a has an amplitude of 2, and wave b has an amplitude of 2. what will happen when the crest of wave a meets the trough of wave b? they will interfere to create a crest with an amplitude of 0. they will interfere to create a crest with an amplitude of 2. they will interfere to create a crest with an amplitude of 4. they will bounce off each another.

When an object moves in uniform circular motion, the direction of its acceleration is a) in the same direction as its velocity vector. b) in the opposite direction of its velocity vector c) is directed toward the center of its circular path. d) is directed away from the center of its circular path. e) depends on the speed of the object.

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?

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?
