What is the answer to this question? Two large books are stacked on top of each other on a table(Figure 3). The mass of each book is 6.5 kg. Given that the coefficient of static friction between the bottom book and the table is 0.15, what is the lowest the coefficient of static friction between the books can be in order to apply force and move both books?

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
