An electric field (sometimes called E-field [1]) is a physical field that surrounds electrically charged particles.In classical electromagnetism, the electric field of a single charge (or group of charges) describes their capacity to exert attractive or repulsive forces on another charged object.
Electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work/energy needed per unit of electric charge to move the charge from a reference point to a specific point in an electric field.
Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest.
Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium. They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes.
where v 1 is the terminal velocity (i.e. velocity in the absence of an electric field) of the falling drop, η is the viscosity of the air, and r is the radius of the drop. The weight w is the volume D multiplied by the density ρ and the acceleration due to gravity g. However, what is needed is the apparent weight.
The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI).. One tesla is equal to one weber per square metre.
This type of motor is used in GM's Chevrolet Bolt [1] and Volt, and the rear wheel drive of Tesla's Model 3. [2] Recent dual motor Tesla models use a combination of a permanent magnet motor at the back and traditional induction motor at the front.
The SS Ourang Medan was a reported ghost ship and proposed urban legend of the 1940s. The vessel was supposedly discovered adrift after briefly broadcasting an SOS.The ships that responded to the SOS were reported to have discovered all the crew dead with their eyes open and their faces frozen in shock, as if they were witnessing a horrific scene.
