How does volcanic activity on io affect its surface?
how does volcanic activity on io affect its surface?
a. the volcanoes on io create fires on the surface that are visible from telescopes on earth.
b. gases from volcanic activity condense and form a type of snow on io that blows into drifts that have been photographed by satellites that have flown past io.
c. debris from volcanic activity has covered over impact craters on its surface.
d. the lava from the volcanoes has deposited metals on the surface that cause io to reflect most of the sunlight that hits io.

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field. it is in the opposite direction from that of the original external field. it has a direction determined entirely by the charge on its surface. it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
