The paradox of a charge in a gravitational field is an apparent physical paradox in the context of general relativity. A charged particle at rest in a gravitational field, such as on the surface of the Earth, must be supported by a force to prevent it from falling. According to the equivalence principle, it should be indistinguishable from a ...
When charged particles move in electric and magnetic fields the following two laws apply: Lorentz force law: = (+),; Newton's second law of motion: = =; where F is the force applied to the ion, m is the mass of the particle, a is the acceleration, Q is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.

Electrostatic discharge ( ESD) is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often creating a visible spark associated with the static electricity between the objects. ESD can create spectacular electric sparks ( lightning ...
Powers stresses this, though: Struggling with word finding and speaking more slowly doesn’t mean you have dementia. “But in some people, it can be the first sign of dementia,” he says ...
When emails go missing in AOL Mail, it's often due to a few simple things; either the message is in the wrong folder, your third-party mail client's settings, or your account was deactivated due to inactivity. Check your other folders. The first thing place to check if you're missing mail is to check your other folders.
A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry . A typical modern shaped charge, with a metal liner on ...
