Investigating Inclined Planes Plane height Plane length Force required to move 10 gram objects 100 cm 10 N 50 cm 200 cm 5 N 50 cm 300 cm 3 N A student investigated the effect of inclined planes on the force required to move an object up a vertical height along the sloped plane. What conclusions can best be made from the data from the experiment shown in the table here?

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.
