Achild with mass 40 kg sits on the edge of a merry-go-round at a distance of 3.0 m from its axis of rotation. the merry-go-round accelerates from rest up to 0.4 rev/s in 10 s. if the coefficient of static friction between the child and the surface of the merry-go-round is 0.6, does the child fall off before 5 s?

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?
