The basic barometer can be used to measure the height of a building. if the barometric readings at the top and the bottom of a buikding are 730 and 755 mmhg, respectively, determine the height of the building. assume an average air density of 1.25 kg/m^3. provide with a simple sketch and graph it (hydrostatic pressure).

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.
