the radius of sphere is 12.4cm assuming an uncertainty of one in the last figure calculate the percentage error in the radius also calculate the surface area and volume of the sphere using A = 4pie r^2 and V = 4/3pir^3 and calculate the percentage error in A and V

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?
