Monica took a train 30 miles south to cincinnati. then she took a different train 18 miles east. draw a vector diagram showing monica's trip, including the resultant vector.

the vector diagram should start with a set of x-y axes. From the origin, draw a line down 30 units (miles), and from that point draw a line to the right 18 units. To draw the resultant vector, you simply connect the origin to the final point, making a triangle.

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.
