Which of the following describes crevice corrosion?
Two metals/alloys of different compositions are coupled while exposed to an electrolyte.
One element is preferentially removed as a result of corrosion.
Corrosion resulting from the combined action of chemical attack and mechanical abrasion or wear.
Localized corrosion that may be initiated at a surface defect.
Oxidation and reduction reactions occur randomly over the surface.
Corrosion that results from a difference in concentration of ions or dissolved gases in the electrolyte.
Corrosion resulting from the combined action of an applied tensile stress and a corrosive environment.
Corrosion that occurs preferentially along grain boundaries.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
