Which TWO statements are true about a system? 1. A system is a group of objects analyzed as one unit.

2. Energy that moves across system boundaries is conserved.

3. There's only one way to define the boundaries of a system.

4. All systems are made by humans.

By dividing you can find the answer

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.
