4 dni temu · A gravitational field can cause a rotation of the polarisation vector of light. This phenomenon is known as the gravitational Faraday effect. We study the gravitational Faraday effect of linearly polarised light propagating in the gravitational field of a weak plane gravitational wave (GW) with “ $$+$$ + ", “ $$\\times $$ × ", and elliptical polarisation modes. The corresponding ...
4 dni temu · By charging it up, we would expect a change in mass of about 2.5 × 10 −11 g or 2.5 × 10 −7 µN, ... Obviously, changing fundamental constants will have an effect on gravity. The only known ...
1 dzień temu · Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity).When unspecified, "time dilation" usually refers to the effect due to velocity. After compensating for varying signal delays resulting from the changing ...
3 dni temu · A simple gravity pendulum [1] is an idealized mathematical model of a real pendulum. [2] [3] [4] It is a weight (or bob) on the end of a massless cord suspended from a pivot, without friction.Since in the model there is no frictional energy loss, when given an initial displacement it swings back and forth with a constant amplitude.The model is based on the assumptions:
4 dni temu · Gravity or gravitation is a natural phenomenon by which all things with energy are brought toward (or gravitate toward) one another, including stars, planets, galaxies, and even light and sub-atomic particles.
5 dni temu · Gravitational waves are transient displacements in a gravitational field—generated by the motion or acceleration of gravitating masses—that radiate outward from their source at the speed of light. [1] They were first proposed by Oliver Heaviside in 1893 and then later by Henri Poincaré in 1905 as the gravitational equivalent of electromagnetic waves. [2]
3 dni temu · This study investigates how various functional groups affect the adsorption of carbon dioxide (CO 2) in pillar[5]arenes (P[5]A) at the aim of enhancing CO 2 capture in P[5]A for environmental applications. Density functional theory (DFT) and density-functional-based tight-binding (DFTB) methods were employed to investigate the adsorption behavior of CO 2 in pillar[5]arenes (P[5]A) with various ...
