Um fio de metal de resistência R é cortado em três partes iguais que são conectadas lado a lado para formar um novo fio cujo comprimento é igual a um terço do comprimento original. Determine a resistência desse novo fio

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )

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.
