Noise-cancelling headphones often utilize the wave behavior of interference to make the music you want to hear louder and the noises around you silent. Using your understanding of interference, explain how this would be possible?

Atomic nuclei of almost all elements consist of

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.
