As we saw in Chapter 7, a central force field that is also conservative must be spherically symmetric, and some of the most important fields in nature (notably electrical and gravitational) are precisely of this type. The frequent occurrence of spherically symmetric models to describe physical ...
By Newton's second law, the motion under various forces is obtained [53]: (39)F=md2rdt2 where F is the atomic force, r is the atom co-ordinate vector, and m is the atom mass. Given the large number of molecules, the workload is too large for analytical algorithms. Therefore, when...
The effect of normal market forces may at times be countered by intervention by central banks and other bodies. At times, exchange rates, and prices linked to such rates, may rise or fall rapidly. Currency Exchange Currency exchange involves bid-ask spread. Online Investment Trading Services ...
An unusually damaging Mw 4.9 earthquake occurred on November 11, 2019 in the south east of France within the lower Rhône river valley, an industrial region that hosts several operating nuclear power plants. The hypocentre of this event occurred at an
Dislocations are linear defects in crystals and their motion controls crystals’ mechanical behavior. The dissipative nature of dislocation propagation is generally accepted although the specific mechanisms are still not fully understood. The inertia, wh
Astrophysical plasma is often an extremely tenuous hot gas of charged particles, without net charge on average. If there are very few encounters between particles, we need only to consider the responses of a particle to the force fields in which it moves
Opposition parties have called for Maekawa, who has admitted to having knowledge of documents that could be potentially damaging to Abe, to be summoned to the Diet to give testimony under oath. Maekawa has said that along with several other ministry officials, he is aware of the documents and...
My improved meter is also adaptable for other uses, such as for installation in a pipeline to measure accurately the volume: of fluid flowing under pressure through the pipeline, etc. My invention relates particularly to the improvements in the valve and valve port means embodied in the meter...

There is no external energy flux within the gyroscopic system under gravity and it will be referred to as a passive gyroscopic system. For such a system, the energy is conserved. The motion of gyroscopic spinners is usually characterised by the angular coordinates \(\theta \), \(\phi \) ...
