Why do the Planets Revolve Around the Sun?

-
If the planets did not revolve, the Sun's gravitational pull would drag them inwards. If they moved very quickly, they would fly off into the space. The closer a planet is, the faster it must move. All the planets move in the same direction, because probably they were formed from the same spinning cloud of material that also made the Sun. All the planets except Venus and Uranus spin in anti- clockwise direction.

The first mechanical clocks are believed to have been made in China in 1088 AD. Later in 1200s, they were first made in Europe. Such clocks made in Europe were driven by a weight on the end of a cord wound round a drum. As the drum rotated, it turned the hands of the clock. The earliest known clock was made in Spain in 1276 AD and the oldest mechanical clock that still works is in Salisbury cathedral in Britain. It was made in 1368. These clocks had devices called escapements to keep the hands turning at the correct rate, so that the clocks depicted the correct time.

A bit is the smallest piece of information that a computer can process and a byte is a group of eight bits operating together as a single unit. The word bit comes from 'binary digit'. A bit can only have two values , zero or one. Every character keyboard can be represented by a group of eight bits, a byte. For example, the letter A is represented by 01000001 and the number 8 by 00111000 . Every character typed on a computer, or sent to another device, such as a printer is represented in this way.
