solar motion lights

Oceana : merkaba the Motion Picture Expanded Addition Chapter 15


Satellite motion in physics? How to solve this problem?

r1 d1 = x R2 x D2 T1 ^ 2/r1 ^ 3 = r2 ^ 2/r2 ^ 3 = 4pi ^ 2 / G (Mcentral) r ^ 3 = t ^ 2 x G x Mcentral / Fg 4pi ^ 2 = G x m1 x m2 / r ^ 2 Acentripetal = G x M / r ^ 2 = v ^ 2 / rv = sqrt (G x M / R) Can use any of these ways to resolve this? And please explain. A new solar system has been Stay discovered around Epsilon Eridani, about 10.5 light years away from Earth. There are 2 known planets orbiting the star. One is about 1.5 times the size of Jupiter with an orbital period of 6.85 years and the earth orbital radius of about 2.2 AU (astronomical unit = distance from Earth to our sun). If the other is about the size of Neptune, and has an orbital period of 2.6 years, what is its orbital radius?

The sizes are irrelevant. The answer is entirely in R ^ 3 = t ^ 2 x G x Mcentral / 4pi ^ 2 which is Kepler's third law. For the first planet that reads 2.2 ^ 3 = 6.85 ^ 2 GM/4pi ^ 2 * F where F is a constant factor that allows you to make your units consistent (I used astronomical units and year and time will not work if expressed M and G units Yes, but F is responsible for that and need not be calculated) for the planet that you have r ^ 3 = 2.6 ^ 2 GM/4pi ^ 2 * F so as to divide the whole of the constant drop out and we get: r ^ 3/2.2 ^ 3 = 2.6 ^ 2/6.85 ^ 2 or = 2.2 * cubicrootof (2.6 ^ 2/6.85 ^ 2) = 1.15 AU
