In subject area: Earth and Planetary Sciences The Earth's gravitational field is defined by the distribution of mass within the Earth and its surroundings, including variations caused by factors like tides, atmospheric disturbances, and mantle convection. This field can be observed using satellites or...
So, Jupiter started migrating to the Sun, but when Saturn appeared there was a complicated gravitational effect which reversed the migration, and the planets moved further from the Sun. Thanks to Saturn, the giant planet Jupiter changed trajectory.所以,木星开始向太阳迁移,但当土星出现时,一个复杂...
The mass of the Earth can be calculated using Newton’s law of gravitation, which would be due to the total (F), which is equal to the gravitational constant multiplied by the planet’s mass and the mass of the object, divided by the square of the planet’s radius. We set this equal...
As one knows, strong discrepancies are found between the different precise measurements of the gravitational constant carried out in Earth-based laboratories. While the precision is increasing in different laboratories and with various methods, these measurements are even more and more discordant. We ...
It has long been assumed that if the gravitational constant G was larger in the past, the Earth's radius had to be smaller. The assertion holds provided th... VM Canuto - 《Nature》 被引量: 19发表: 1981年 Palomagnetic Indications of an Increase in the Earth's Radius No Abstract availa...
where\(P_i\)is the partial pressures,gis the gravitational acceleration given by\(g = \frac{GM}{R^2}\), whereGis the gravitational constant,\({\bar{m}}\)is the mean molecular mass of the atmosphere,\(m_{\mathrm{i}}^{\mathrm{atm}}\)is the molecular mass of the volatile species...
In the process of the Earth′s expansion as gravitational constant decrease,the density structure of inner core and mantle is two evident different the area,it is clearly that inertia increase of the inner core and the mantle is not synchronization with the state of ideal inertia expansion.In ...
When all are aligned in a line, the gravitational signal of the Sun and the Moon acts in phase on the Earth. When these three bodies form a right-angled triangle, however, the gravitational signal of the Sun and Moon acting on the Earth are out of phase. It is this same phase drift...
One can simply calculate the centripetal acceleration at Earth’s equator, given by (6378 km) x (2##\pi##/24 hours)##^2##, and see that it is roughly one part in three hundred of Earth’s average gravitational field. This leads to an expectation that on a spherically symmetric but ...
The gravitational torques exerted by other solar system bodies on the Earth are the cause of the nutations and can be precisely computed [4], [5], [6]. The response of the Earth to this forcing allows us to constrain interior properties and is modelled in terms of a transfer function [...
