A small particle with positive charge q = +3.75 * 10-4 C and mass m = 5.00 * 10-5 kg is moving in a region of uniform electric and magnetic fields. The magnetic field is B = 4.00 T in the +z-direction. The electric field is also in the +z-direction and has magnitude E = 60.0 N>C. At time t = 0 the particle is on the y-axis at y = +1.00 m and has velocity v = 30.0 m>s in the +x-direction. Neglect gravity. (a) What are the x-, y-, and z-coordinates of the particle at t = 0.0200 s? (b) What is the

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
