Find the concentration of H+ ions at a pH = 11 and
pH = 6. Then divide the concentration of H+ ions at a
pH = 11 by the of H+ ions at a pH = 6. Record your
answer in Table C.

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
