Which statement best describes inertia? a) a piece of paper will fall toward earth at a faster rate than a baseball will b) if earth had no atmosphere, a baseball would fall toward earth at a faster rate than a piece of paper would. c) more force is needed to stop a moving car than to stop a train moving at the same speed. d) more force is needed to stop a moving train then to stop a car moving at the same speed.

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.
