While visiting the observatory where her mother works, Maria saw a large object with a bright tail, through a high powered telescope. The object looked like a white streak crossing the sky. It was not entering Earth's atmosphere but looked as though it was orbiting Earth. Maria told her mother that she saw a meteor and theorized that it must have come from the asteroid belt and would cause damage when it struck Earth. Was Maria correct in her assessment of the object and its devastating path?

Critique Maria's analysis and create an argument that either supports or disproves her theory.

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
