Avertical scale on a spring balance reads from 0 to 160 n . the scale has a length of 11.5 cm from the 0 to 160 n reading. a fish hanging from the bottom of the spring oscillates vertically at a frequency of 2.95 hz .

Hey hope you get the answer but i suck at math sorry : (

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.
