The Satellite Award for Best Actress in a Motion Picture is one of the annual awards given by the International Press Academy. In 2011, the IPA pared down its Satellite nominations in the motion picture categories from 22 to 19 classifications; the change reflects the merger of drama and comedy under a general Best Picture heading, including the Best Actor/Actress headings and the Best Supporting Actor/Actress headings.

1. ### Artificial satellite tension

Hi, I need to prove that the tension for artificial satellite consists of two points of mass m/2 connected by a light rigid rod of length , the tension in the rod is - $$T=\frac{3}{4}\frac{Gmm'l}{a^3}-\frac{1}{4}\frac{Gm^2}{l^2}$$ the satellite is placed in a circular orbit of radius a>>l...
2. ### A Explanation of the Geocentric Celestial Reference System?

Hi there guys, I was wondering does anyone have a layman's explanation of the GCRS as defined in the title. I am confused as to whether this is an inertial or non inertial system. In text modern reference books such as this (chapter 10, section 10.3.2) they define rotating/non rotating...
3. ### Apparent (clearly false) contradiction - Kepler's Third Law

Homework Statement When considering a satellite in geosynchronous orbit, its speed is zero across (relative to) Earth's surface. From Kepler's third Law: T2=(4π2r3)/(GM), we can derive that v2=GM/r This would tell us that as the radius of a satellite to Earth's centre increases, its velocity...

### Satellite Motion

1. The problem statement, all variables, and given/known data Satellites orbiting the Earth are often put into orbit at different heights around the planet. What affect will this have on the motion of the satellite and how exactly would the motion of a very high orbit satellite differ from one...
