1. An 1875 watt hair dryer has a resistance of 8.3 2 and a capacity of 15 amps. If 110 V of electricity is delivered to the hairdryer is the hairdryer operating at its fullest capacity? Explain your answer and support your answer with mathematical evidence.

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.

The appropriate concentration for an iodine sanitizer is
