Match each wave characteristic to its description. 1. the height of a wave from its equilibrium position
2. the distance between adjacent crests or troughs
3. the number of cycles of a wave per second

3. a particle with initial velocity v⃗ 0=(5.85×103m/s)j^ enters a region of uniform electric and magnetic fields. the magnetic field in the region is b⃗ =−(1.35t)k^. you can ignore the weight of the particle. a. calculate the magnitude of the electric field in the region if the particle is to pass through undeflected, for a particle of charge +0.640 nc.
