A measure of the separation of positive and negative electric charges within an electrical system, i.e. a measure of the system's overall electrical polarity. The SI unit for measuring electric dipole moment is the coulomb-metre (C⋅m), but the debye (D), a non-SI unit, is also widely used in chemistry and atomic physics. electrical conductivity
Action at a distance is the concept in physics that an object's motion can be affected by another object without the two being in physical contact; that is, it is the concept of the non-local interaction of objects that are separated in space.
curvilinear motion The motion of a moving particle or object that conforms to a known or fixed curve. Such motion is studied with two coordinate systems: planar motion and cylindrical motion. cyclotron A type of particle accelerator in which charged particles accelerate outwards from the center along a spiral path.
Matter exists as a spherical standing wave interacting with other matter. Thus, the constant expansion of space allows our brain waves to tune into a particular wavelength and move things with the ...
A measure of disorder; the higher the entropy the greater the disorder. [5] In thermodynamics, a parameter representing the state of disorder of a system at the atomic, ionic, or molecular level; the greater the disorder the higher the entropy. [6] A measure of disorder in the universe or of the unavailability of the energy in a system to do ...
Artificial satellites move along curved orbits, rather than in straight lines, because of the Earth's gravity. Translated from Latin, Newton's first law reads, Every object perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon. [note 3]
The energetic neutrons and soft X-rays released by the detonation, which do not appreciably penetrate matter, [79] are converted into heat upon encountering the object's surface matter, ablatively vaporizing all line of sight exposed surface areas of the object to a shallow depth, [78] turning the surface material it heats up into ejecta, and ...
Thirty years ago this month, the Soviet Union collapsed, and Ukraine broke away from Moscow's control. Russian President Vladimir Putin has never gotten over it.. That, more than anything ...
