Process gravitational field

In 1994, a unique incident occurred the impact of the Shoemaker-Levy comet on the Jovian atmosphere. Die strong gravitational field of Jupiter caused the comet to break up before it could enter the atmosphere, and the parts of the comet crashed separately into the atmosphere one after the other. This unique spectacle was observed by many observatories and also by the Galileo spacecraft and the Hubble telescope. It led to the discovery of yet another phenomenon the most intensive aurora effects in the solar system, observed at Jupiter s poles. Astronomers assume that the energy for these comes from the planet s rotation, possibly with a contribution from the solar wind. This process differs from that of the origin of the aurora on Earth, where the phenomenon is caused by interactions between the solar wind and the Earth s magnetic field. [Pg.48]

This is processional motion and the top is said to be processing around the vertical axis of earth s gravitational field. [Pg.244]

Even when a system is in a steady state other than equilibrium certain physical quantities may be stationary Markov processes. An example are the current fluctuations in the circuit of fig. 7 when a battery is added, which maintains a constant potential difference and therefore a non-zero average current. Another example is a Brownian particle in a homogeneous gravitational field its vertical velocity is a stationary process, but not its position. [Pg.82]

Section IV reviews our more recently developed 4D ether model [102-104], which is based on the premise of the existence of E. Rest mass is associated to a flow of primordial fluid (preons). This novel dynamic concept of mass solves at once several longstanding difficulties two of them are (1) the infinities associated with electric and gravitational fields and (2) the stability of orbits under Coulomb attraction. Indeed, there is a permanent flow of momentum across a particle (source) the momentum flux is occasionally tapped by interaction with a (test) particle. Such process does not change the total momentum flux available at the source hence, there is no loss of potential energy as in the conventional interpretation. The total momentum that crosses a source is, of course, infinite in an infinite time, but the source is always finite. [Pg.379]

On the other hand, most, if not all, ordinary novas occur in double-star systems. For example, consider a red giant in the vicinity of a white dwarf. The gravitational field of the white dwarf may pull hydrogen from its larger companion, thereby initiating fusion and causing a nuclear explosion, a nova, that launches a small amount of gas into space. The process may repeat many times. [Pg.114]

The relevance list must also include universal physical constants such as the universal gas constant, R, the speed of light in a vacuum, c, or even the acceleration of a gravitational field (on Earth the acceleration due to gravity, g), if these constants influence the process concerned. The fact that a relevant physical quantity is a constant can never be a reason not to include it in the relevance list By failing to consider the relevance of gravitational acceleration, the chemical engineer may find he has made a serious mistake ... [Pg.27]

Analysis of experimental data about drainage of low expansion ratio foams [24,67] in which the flowing process does not start at the moment of foam formation, as well as the fact that the AVL t (t) curve lacks an inflection point (or, respectively, a maximum of rate dVJdx), proves that Eq. (5.46) is one of the simplest and physically well grounded kinetic dependences of foam drainage in gravitational field. [Pg.426]

In several cases the lowest foam layers decay very slowly, which seams to be a characteristic feature of the kinetics of foam column destruction. The decrease in border capillary pressure can be regarded as the main reason for such a decrease in the rate of decay in gravitational field (see Section 6.5.2). At low surfactant concentrations the lower foam layers are stabilised, because the surfactant concentrates in them as a result both of internal foam collapse and decay of the upper layers. When the foam is destroyed by addition of antifoams, the delay of this process occurs because the antifoam solubilises in the surfactant solution during the breaking of the foam (see Sections 9.1 and 9.3). [Pg.475]
