HELP ASAP PLS Explain how an electric current can travel through conductive materials. Identify three different materials: one that is a good conductor, one that is semi-conductive, and one that is a good insulator. Explain why each material possesses its specific properties and suggest an application for its use in everyday life.

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
