Using the equation P2 = (4 * pi2 * a3)/(G(M+m)) to find the orbital period of Earth where: P = orbital period a = semi-major axis = 1.50e11 m G =...
noun In astronomy, the time of the revolution of a planet or satellite around its primary. Also orbital period. noun In geology, technically, one of the larger divisions of geologic time of either the second or the third order, measured by the time of deposition of a ‘group’ or ‘syste...

In the equation above, zb is the altitude at which the airburst occurs, z⋆ is the altitude at which the comet begins to disrupt, H is the scale height of the atmosphere, l=L0sin(θ)ρobj/(CDρa(z⋆) is the dispersion length scale, fp=(L(z)/L0) is the pancake factor...
A partial least squares structural equation modeling (PLS-SEM) approach was used to evaluate the data and test the hypotheses. The results of the PLS-SEM analysis method demonstrate that environmental integrity, social equity, economic prosperity, and technological adaption had a positive relationship ...
period of a planet with the length of its day, or vice-versa. So you might read that Mars has a day length of 24 hours and 37 minutes, which is actually its rotation period, or that Venus rotates in 117 days, which is actually the length of its day. Perhaps in the case of Mars...
the earth. As for bodies that revolve around the sun, we speak not only of the sidereal periods of planets but also of, for example, the sidereal periods of comets. The relation between a planet’s sidereal periodT, its synodic periodS, and the sidereal yearEis given by the equation ...
Yet it is also in the Devonian that the Earth suffered one of its greatest biodiversity crises, one of the ‘Big Five’ mass extinctions of life, and it is in the Devonian that the entire climate of the planet switched from a hot greenhouse state to a cold icehouse phase. The Devonian ...
Non-continuation of the periodic oscillations of a forced pendulum in the presence of friction A well known theorem says that the forced pendulum equation has periodic solutions if there is no friction and the external force has mean value zero. In t... R Ortega,SM Tarallo - 《Proceedings ...
