Tyler's favourite number is 8642, and he tries to fit it into everything he does. If he wishes to do that much work by climbing stairs, how many stairs must he climb if each stair is an average of 18 cm tall and Tyler's mass is 64 kg?

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.
