SCIENCE HOMEWORK A  helium–neon laser  or  HeNe laser , is a type of  gas laser  whose gain medium consists of a mixture of 85% helium and 15% neon inside of a small bore capillary tube, usually excited by a DC  electrical discharge . The best-known and most widely used HeNe laser operates at a wavelength of 632.8 nm, in the red part of the visible spectrum. Bronze  is an  alloy  consisting primarily of  copper , commonly with about 12%  tin  and often with the addition of other metals (such as  aluminium ,  manganese ,  nickel  or  zinc ) and sometimes non-metals or  metalloids  such as  arsenic ,  phosphorus  or  silicon . These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness,  ductility , or machinability. An  ice cube  is a small, roughly  cube -shaped piece of  ice (frozen water), conventionally used to cool  beverages Ginger ale  is a  carbonated   soft drink  flavoured with  ginger  in one of

THE NATURE OF MATTER ? All atoms have the same number of protons (positively charged) and electrons (negatively charged). Therefore all atoms have a neutral charge (the positive and negative charges cancel each other). Most atoms have approximately the same number of neutrons as they do protons or electrons, although this is not necessary, and the number of neutrons does not affect the identity of the element. WHAT IS SCIENCE ? Science  (from  Latin   scientia , meaning "knowledge") [1] [2] :58  is a systematic enterprise that builds and organizes  knowledge  in the form of testable  explanations  and  predictions  about the  universe . [a] Contemporary science is typically subdivided into the  natural sciences , which study the  material universe ; the  social sciences , which study people and societies; and the  formal sciences , which study  logic  and  mathematics . The formal sciences are often excluded as they do not depend on  empirical observations. [3

Energy is the primary ‘fuel’ for social and economic development, but energy and energy-related activities also have significant impacts on other areas such as the environment and technology impacts. Therefore, it is important for decision-makers to have access to reliable and accurate data in a user-friendly format. The energy sector has long lead times, and therefore any long-term strategy should be based on sound information and data. Detailed resource data, selected cost data and a technology overview in the main WER report provide an excellent foundation for assessing different energy options based on factual information supplied by the WEC members from all over the world. Some of the changes we have seen over the last couple of years are: The past 15 years have seen unprecedented change in the consumption of energy resources Unexpected high growth in the renewables market. Growth of unconventional resources Improvements in technology evolution for all the resources De
