5. the generation of electricity relies primarily on chemical reactions mechanical energy wind farms bioconversion

Option B, Mechanical energy

Explanation:

In the electricity production, whatsoever be the medium/raw material used for electricity production, the ultimate goal is to rotate the turbine of the generator which is connected to a coil held between two magnets.  This is so because until unless the coil rotate between the magnets no electricity will be produced. Since rotation of a coil is linked to rotation of turbine which is nothing but a kind of mechanical exercise. Thus, it can be said that the generation of electricity relies primarily on mechanical energy.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
