Randall is able to paddle his canoe at 2.0 m/s in still water. He drops the canoe into a river which is flowing north at 1.5 m/s . Draw sketches showing how to determine the direction of the magnitude and direction of the velocity of the canoe relative to the Earth using vector addition: no need for drawing

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

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.
