Mark all of the following that could be true of an object in free fall. a. The particle may be moving with constant speed. b. The object may be moving upward. c. The object may be moving downward. d. The object may be momentarily at rest. e. The particle may be moving with an acceleration that is not constant.

Ibelieve that the correct answer is: c. along plate boundaries

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.
