Complete the paragraph to describe binary systems. A binary star system is made of stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to. Astronomers can also spot the dimmer star by observing a phenomenon called a(n) binary. This happens when the dim star passes in front of the bright star.

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?
