An electric bulb is marked 40volts ,230w another bulb is marked 40w,110v a. calculate the ratio of their resistance
b. the ratio of their energy
c. find the charge on each bulb
d. which of the two bulbs can hold enough .​

Gravity bc it’s gravity

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.

Ithink the answer is fusion 

Newton's first law describes something special that results from the sum of all the external forces (including gravity) on an object.
