A copper refinery produces a copper ingot weighing 131 lb. If the copper is drawn into wire whose diameter is 8.25 mm, how many feet of copper can be obtained from the ingot? The density of copper is 8.94 g/cm3. (Assume that the wire is a cylinder whose volume is V = pr2h, where r is the radius and h is its height or length.)
Please review the occurrence and cycling of calcium in nature, along with its use. Analyze and evaluate the article as to it's contemporary relevance regarding the elements availability, health implications and environmental impact.
