with the use of the hubble space telescope, scientists recently discovered a giant runway star. it is 90 times larger than the sun and is very hot and blue-white in color. why does the sun appear to be brighter than this runway star when viewed from the earth?

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.

Ibelieve the answer is d. macula  hope my answer has you : )

Answerit is comparative because this experiment is comparing the results of the volume at minimal pressure and then increases it; ; ;
