I'm reading my physics text, Matters and Interactions, and there is an example about why Hydrogen gas is transparent in visible light. It says it is transparent because visible light has energies from 1.8 to 3.1eV, and in order to move a Hydrogen atom from ground state to the first excited...

so how does this sound:2u/(u^2(1+u)) du Then I complete the partial fraction decomposition?

u = sqrt(x) du = 1/2sqrt(x) x = u^2 ∫1/(u^2 + u^3) ∫1/(u^2(1+u)) Then I use partial fractions decomposition A= 1 B = -1 ∫1/u^2 - ∫1/(1+u) substitute in u ∫1/x - ∫1/(1+sqrt(x)) ln(abs(x)) - ln(abs(1+sqrt(x))) Answer: ln((x/(1+sqrt(x)))

Homework Statement Going over past exam problems, stuck on this one. Attached Calc 2, topics include for this exam integration techniques, such as partial fractions, improper integrals, trig sub, and series. Question reads: Use a substitution to compute: (see attached) Homework...

Thank you! After reading a second time, I noticed it said "points", plural, and that lines up with the explanation. Thanks for helping me.

Okay, thank you. The textbook goes on from their definition to say "We have given a one-to-one correspondence between points P in space and ordered triples (a,b,c) in R^3". I think I understand this statement to be the Point P is located at (a,b,c). Is this also a fair comprehension?

I am not too used to reading mathematical text using symbols. I need some help confirming what I have in my textbook. The book is describing a point in 3D space using the definition R x R x R = {(x,y,z) | x,y,z \in R} and R is all real numbers Using this source describing the...

Hi forum goersI'm reviewing some coursework for my General Chemistry class and cannot seem to find a reasonable explanation of why amino acids exist as zwitterons in solid state and ph7 solutions. I'm fairly certain the explanation has to do with its solubility in water, but I am not sure. Here...

Thanks.

hybridization of carbon--is my teacher right? https://www.myhaikuclass.com/c/937570/file/show/15157688.jpg (comes up as a download) Hi, in the link above, I am looking at the 1st image. This is the answer my teacher offered, but at 7 and 8, shouldn't the hybridization be sp, not sp2...

Is boiling basically a really high vapor pressure?

Ffr = (.25)(-9.2) + (.25)(9.8) = .15 N finally, 5th times the try. Thank you very much for the help

negative Ffr = (.25)(-9.2) + (.25)(-9.8) Ffr = -4.75 N Thanks a bunch!

Okay, I'm settling with this. Ffr - Fm = may Ffr = may + Fm Ffr = (.25kg)(9.2m/s2) + (.25kg)(9.8m/s2) Ffr = 4.75 N
