Because so little can be found of the first rocks to form on Earth, the best evidence for the early formation of our planet
comes from studying which of the following?

A Asteroids, lunar rocks, and other objects in our solar
system
B Weathering and erosion patterns in extreme
environments

C The formation of gaseous elements through fusion in
our sun

D Fluctuations in chemical compositions of successive
lava flows

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?
