I was wondering if you guys could help me with a problem. Got a midterm tomorrow and cannot figure this one out. the subject is physical chemistry - quantum mechanics.

Calculate the minimum excitation energy of a proton constrained to rotate in a circle of radius 100 pm around a fixed point.

Thanks in advance.

I have been studying for an upcoming exam.
[Factorizing Cubic Functions.]

x^3 -7x + 6 = 0

I am abso-fucking-lutely stumped.

This has appeared in 2 of the past 11 years tests, and it may very well be in the next.

Need help. (Synthetic Division? Overthinking?)
Not a solution (Wolfram can give me that)

I'm ignorant on the subject.

Why can magnets not be used to make perpetual motion?

Ok good point im less scared but still untill you explore every single possibilty we still dont know what the fuck will happen until we DO it.

Of course you can simulate and make theories but that doesnt make it 100% accurate so again, anything can happen imo.
