How many different spectral lines could be emitted if mercury vapor were excited by photons with 6.67 eV of energy? (Hint: An electron couldmove, for example, from energy level Es to E3, then from Ez to E2, and
then from Ez to Ep.)

answer; ///(c); ///bronchi i do believe this is the correct answer,; plz check first..good luck

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
