Which statement supports the use of large, representative samples in a study? O Fellow scientists are less likely to believe a study that uses a small sample.
O The amount of data able to be collected from a small sample may be insufficient.
o The study will be over too soon to gather sufficient data.
o The traits of the sample members may differ randomly from the traits of the population as a whole.

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.
