Assuming the heterocyclic ring above to be planar: Give the number of electrons that are contributed to the pi system of the heterocyclic ring by: atom 1; atom 2 ; atom 3 . Enter NA for atom 3 if the structure above has only two numbered atoms. How many electrons are in the pi system of the heterocyclic ring

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?
