In the figure(Figure 1) the coefficient of static friction between mass mA and the table is 0.43, whereas the coefficient of kinetic friction is 0.29.What minimum value of mA will keep the system from starting to move?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Explain why electric current cannot exist if a current doesn't have a voltage source.

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
