A force of 10.5 N is used to move a box on a horizontal, friction-free surface, at a distance of 8.5 m. (a) Determine the work that the force performs on the box. (b) What work does the force do if you move the box on a 30 degree surface at a distance of 4.5 m? 10 point
Two blocks, stacked one on top of the other, can move without friction on the horizontal surface shown in the figure.(Figure 1) The surface between the two blocks is rough, however, with a coefficient of static friction equal to 0.45. a. If a horizontal force F is applied to the 5.0-kg bottom block, what is the maximum value F can have before the 2.0-kg top block begins to slip? b. If the mass of the top block is increased, does...

How does the impedance of an electrode change with its surface area? (increase / decrease) How does the parallel capacitance (double-charge layer capacitance) of an electrode change by its surface area? (increase / decrease) Draw the electrical equivalence of an electrode/electrolyte interface using 4 passive electrical components.
can you please explain how they got the answers? And
possibly give the name of the reaction of process?
