A geostationary satellite revolving around the Earth is subject to the attractions of all planets in the solar system. Among these planets, the Earth constitutes the basic center of attraction, while the Sun and Moon play a minor role in determining the motion of the satellite. The effects of...
The ratio of nuclear spin-precession frequencies of Hg-199 and Hg-201 atoms were measured for two orientations of magnetic field relative to the earth's gravitational field. It is found that the spin-dependent component of gravitational energy is less than 2.2 x 10 exp -21 eV, a substantial...
作者: Andrew S. Trupin,Raphael P. Panfili 摘要: We have used satellite solutions to the low degree zonal harmonics of the Earth's gravitational potential, and rates of surface accumulation to partially constrain, by means of repeated forward solution, the time rates of thickness change over the...
4 The gravitational field strength on the Moon is less than on the Earth.Which of these is different when done on the Moon compared with when done on the Earth?A A the gravitational potential energy gained by a stone lifted through the same vertical height B the kinetic energy gained by ...
1 An astronaut has a mass of 65kg on Earth, where the gravitational field strength is 10N/kg.(a) Calculate the astronaut's weight on Earth.weight on Earth =...[2](b) Complete the following sentence.The astronaut's weight on Earth is the force.between the astronaut and-[1](c)The...
However, we assumed that the bigger primary is radiating and the second is a non-spherical body that creates a gravitational field as in a continuation fractional potential in the old work; this model can be applied to study the Sun–Earth system in which the Sun is a radiating body and ...
The G-M of [Math Processing Error]MB and [Math Processing Error]MC is equal to 0.84 earth masses, and the G-M of [Math Processing Error]MC and [Math Processing Error]MD is [Math Processing Error]5×1015 solar masses, which identifies universal structures much larger than individual ...
Jupiter possesses the strongest planetary magnetic field in the solar system, more than ten times larger than that of Earth1. It is widely accepted that the Jovian magnetic field is generated by convection-driven motion in the deep metallic hydrogen region of the planet2,3. However, we know ...

Early detection of gravitational field on satellites was performed by in-situ detection of atmospheric density with accelerometers, such as the Challenging Minisatellite Payload (CHAMP) and the Gravity Recovery and Climate Experiment (GRACE), which are two of the most representative near-Earth space en...
