Magnetic fields at the surface of the sun can be strong enough to cause solar material to be completely ejected from its surface. This is called a Coronal Mass Ejection or CME. (It's complicated why CME's occur, but basically the sun is an ionized gas, so the moving charged particles in the gas feel a magnetic force from the sun's field.) Solar material has a density of about 3 times 10^-4 kg/m^3, and the amount of matter released in a...

This problem focuses on the following two concepts: Magnetic fields are created by moving charges only. Magnetic fields can only deflect moving charges. Magnetic Field Creation Which of the following will create a magnetic field? Choose all that apply. A neutron that is stationary. A neutrino that is slowing down from 500 km/h to 400 km/h. An ion that is speeding up from 1000 m/s to 1200 m/s. A proton moving at a constant velocity of 60 mph due north....

Fields on the Page Estimate the maximum magnitudes of the electric and magnetic fields of the light that is incident on a page because of the visible light coming from your desk lamp. Treat the lightbulb as a point source of electromagnetic radiation that is 6% efficient at transforming energy coming in by electrical transmission to energy leaving by visible light. SOLUTION Conceptualize The filament in your lightbulb emits electromagnetic radiation. The brighter the light, the larger the magnitudes of...

1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...

2. Thave 2 equally strong positive charges that I've bolted to the ground. Where can I put a 3rd (mobile) test charge, such that it doesn't feel an overall force from them? What changes if one of those original charges is negative? 3. I have 2 conducting plates, both weighing mass M, with charges q1 and 92 (that I control) on each respectively. I bolt one plate to the ground so it can't move, and I want to levitate the...
