Astronomical Cycles and Their Effects on Planet Earth By Harry Mowat The orbit of the Moon around the sun The Moon orbits around the Earth every 27.3 days. The Moon’s orbit around the Earth is not a circular orbit but more of an eclipse and the orientation or the orbit is not fixed but differs in time. The Earth and the Moon are both actually orbiting the sun (the Moon at a much faster rate) but in the process of that orbit the Moon orbits Earth. This process is the main cause of tide formations

BASIC INPUT/OUTPUT The C++ standard libraries provide an extensive set of input/output capabilities which we will see in subsequent chapters. This chapter will discuss very basic and most common I/O operations required for C++ programming. C++ I/O occurs in streams‚ which are sequences of bytes. If bytes flows from a device like a keyboard‚ a disk drive‚ or a network connection etc. to main memory‚ this is called input operation and if bytes flows from main memory to a device like a display screen

aircraft. The best choice for small aircraft vapour cycle cooling system(VCCS) been used. Vapour cycle refrigeration is the predominant means of air-conditioning in small - and medium-size business aircraft and helicopters. Vapour cycle cooling system (VCCS) is more easier to used on small aircraft because its required a minimum power for a given of cooling and also allow the aircraft to be cooled on the ground as well. The basic function of vapour cycle cooling system(VCCS) is to give accurate cooling
