How should the size of the test charge compare to the amount of charge that produces the field?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

How is zig zagging a form of acceleration?

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
