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.
The triboelectric effect (also known as triboelectricity, triboelectric charging, triboelectrification, or tribocharging) describes electric charge transfer between two objects when they contact or slide against each other. It can occur with different materials, such as the sole of a shoe on a carpet, or between two pieces of the same material.
iPad Air (4th generation) The iPad Air (4th generation), informally referred to as iPad Air 4, is a tablet computer designed, developed, and marketed by Apple Inc. It was announced by Apple on September 15, 2020. Pre-orders began on October 16, 2020, and shipping began a week later on October 23, 2020 alongside the iPhone 12 and iPhone 12 Pro.
Archaeologists discovered a small, clay tablet covered in cuneiform in the ancient ruins of Alalah, a major Bronze Age-era city located in present-day Turkey. Researchers have deciphered parts of ...
Shaped charge. 1: Ballistic cap; 2: Air-filled cavity; 3: Conical liner; 4: Detonator; 5: Explosive; 6: Piezo-electric trigger. 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 ...
AT&T said Friday that data was breached from “nearly all” of its cellular customers and the customers of wireless providers that used its network between May 1, 2022, and October 31, 2022. The ...
The iPad Air (3rd generation) [2] (colloquially referred to as iPad Air 3) is a tablet computer developed, and marketed by Apple Inc. It was announced and released on March 18, 2019, alongside the 5th-generation iPad Mini. The device was released five years after the previous iPad Air 2, as the iPad (5th generation) was released in 2017 as the ...
Electric charge is a conserved property: the net charge of an isolated system, the quantity of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
