KE = 1/2(100 kg)(100 m/s)^2 = 500000 Joules ----------------------- KE = 1/2(100 kg)(50 m/s)^2 = 125000 Joules ---------------------- 5â¦00000 Joules/125000 Joules = 4 ------ The kinetic energy is reduced by a factor of 4 because the speed is squared.
Earth, the fifth-largest of the eight planets in the Solar System belongs to the Milky Way galaxy and is orbiting about 28,000 light years from the center of the galaxy. It is believed that currently it lies about 20 light years above the galaxy's equatorial plane in the Orion spiral arm.
The Counter-Earth is a hypothetical body of the Solar system hypothesized by the pre-Socratic Greek philosopher Philolaus (c. 470 â c. 385 BCE) to support his non-geocentric cosmology, in which all objects in the universe revolve around an unseen Central Fire (distinct from the Sun which also revolves around it). Gor is the name of the Counter-Earth that is the setting for a series of 32 novels by John Norman. 2  The 1969 science-fiction film Doppelgaenger (doppelgÃ¤nger also known As journey to The Far side of The), sun depicts the discovery and investigation of another planet Sharing'earth s orbit on the opposite side of The.  sun
