/sci/

I FREELY ADMIT THAT THIS IS MY FUCKING HOMEWORK

I am not a slacker, this shit is due in four hours, I've been tied up all week doing programming assignments and digital logic design for two different 400 level ECE courses.

Just fucking solve it. This question alone is worth a few tenths of a percent of my final grade and due in four hours. I'm staying up all fucking night to cover for some lazy asses on my digital logic design team.

I really do want to learn how this works though.

To get help you need to at least attempt to do it. I understand that you're bust, but coming onto a board, imposing on the posters and saying "just fucking do it" isn't a good way to get help.

That said, I WOULD help you with this, but I am not myself a physicist and thusly can't really help. There are a couple people on here that know their shit, but you're probably gonna find that there are relatively few /sci/ posters who can.

>>	Anonymous Thu Sep 22 05:28:25 2011 No.3779463 Also A is smaller than the radius of a carbon atom, so B and C, possibly but probably not D.

>>	Anonymous Thu Sep 22 05:43:25 2011 No.3779474 Bumping because despite a good bit of reading, I STILL DON'T KNOW WHAT TYPE OF POTENTIAL WELL THIS IS

>>	Anonymous Thu Sep 22 05:54:25 2011 No.3779490 >>3779474 We all have potential. Some more than others.

>>	Skunkworks !e1337Hykks Thu Sep 22 05:59:25 2011 No.3779497 >>3779495 The tl;dr version is it is an infinite potential well looking for the change in kinetic energy between the zero point energy and first excited state
