Mining Wikipedia
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer depositExploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers whoThe unit of power, the watt, is likewise not a base SI unit but can be defined as 1 J/s (energy per unit time) or, in base units, 1 m2 × kg × s−3 Since the formal definition of the candela is at a single wavelength (at the peak of the photopic luminous efficiency function), V(λ) must be applied to measurements of radiant power produced byIESNA Lighting Handbook PDF Free Download
