Achain 71 meters long whose mass is 24 kilograms is hanging over the edge of a tall building and does not touch the ground.

how much work is required to lift the top 5 meters of the chain to the top of the building?

use that the acceleration due to gravity is 9.8 meters per second squared.

your answer must include the correct units.

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.

Assuming you're referring to significant figures, none of these answer choices are shown to be zero as significant digits. did you, by chance, forget to add something?
