Part 7 The life cycle of a star How does gravity‚ nuclear fusion and mass affect the life cycle of a different sized stars? * Stars initially form from clouds of dust and gas. The force of gravity makes the gas and dust spiral in together to form a protostar. Gravitational energy has converted into heat energy‚ so the temperature rises * When the temperature gets high enough‚ hydrogen nucli undergo thermonuclear fusion to form helium nuclei and give out massive amounts of heat and light

Once it is all the way grown‚ the third stage starts. This stage is the chrysalis. The caterpillar makes a chrysalis. The caterpillar

Examine the case for the waterfall life cycle. Does the waterfall life cycle still play a useful role in modern system development‚ and if so‚ at which stages? The waterfall life cycle model in software engineering was originally designed in 1970 by Winston.W.Royce. The waterfall life cycle model plays a linear act of moving forward of framework activities that is often inconsistent in some field of the software world. In situations where requirements are well defined and stable‚ it is applicable

Product Lifecycle Management Stage 4: Decline The decline stage of the product life cycle is the one where the product ultimately ’dies’ due to the low or negative growth rate in sales (see Figure 1). Profitability will fall‚ eventually to the point where it is no longer profitable to produce‚ and production will stop. As a number of companies start to dominate the market‚ it becomes increasingly difficult for the company in question to maintain its level of sales. Consumer tastes also change

also experienced the different periodic phases of group development‚ which Tuckman (1965) describes in four phases as forming‚ storming‚ norming‚ and performing. These four phases are not sequential and not all groups pass through these phases in a liner way and groups can cycle back to a phase that has already been completed. Group development can be classified in an initial phase where individuals join together for some reason‚ which is the forming phase. We join groups to satisfy a need‚ which

the core as a gaseous shell. The gas that surrounds the core is called a "Planetary Nebula". The core that is left then becomes a "white dwarf". After the white dwarf cools down enough it stops shining and dies‚ forming a "black dwarf". Another life cycle of a star involves a star with a mass of 10 solar masses or more. These stars evolve similarly to stars of about 1 solar mass until they reach "main sequence". The star shines bright until all of its hydrogen has fused to form helium. This takes
