Which of the following statements about flood mitigation is true?(1 point)

It is cheaper to pay for repairs after flooding has occurred than to fund flood mitigation projects.

It costs roughly the same to fund flood mitigation projects as paying for repairs after flooding has occurred.

Minimal research has been done comparing the costs of funding flood mitigation projects to the cost of repairs after flooding has occurred.

It is cheaper to fund flood mitigation projects than to pay for repairs after flooding has occurred.

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
