Marks and Spencer Case

There are eight planets which orbit the sun they where nine before but one of the planet became a dwarf planet and that's called Pluto. Their order of arrangement is mecury, venus, earth, mars, Jupiter, saturen, Uranus, naeptune, it takes the earth 365 days to he sun a year. The time it takes for the planet to orbit the sun is called a year. And the time it takes to spin on its axis is called a year. Planets that are further from the sun have longer years. This is because they have further to travel and they have lower speed. Artificial satellites have many uses including communication observing the universe(e.g weather forecasting) some satellits such as those for tv are placed in geostationary orbits that take exactly 24 hours tthis means that they appear to us to stay still in the sky, so we can use fixed dishes on our houses to receive signal.

Evidence for the big bang theory

When an object moves away from us the waves coming from it becomes spread out. The same thing happens with light if an object is moving away from you quickly, the light is shifted towards longer wave lengths we that it has been red shiftedit means they are moving away ffrom us

the red shift is so big in comparison to,gene therapy i just don t understand the meaning of things gene therapy biology pysics chemistr7yvghiktxdtrhtgyk ygfktr67ietyrskuliunhk gutkkxsu45eThere are eight planets which orbit the sun they where nine before but one of the planet became a dwarf planet and that's called Pluto.
