Yes, sadly.

Could I put the frequency v=c/λ? I don't know whether I'm able to assume the conditions for a vacuum, but it would cancel out λ, the wavelength and then ((e(hv/kT))/(e(hv/kT)-1) would go to zero, which would leave Cp=7R/2. This doesn't seem right but it's more than I had yesterday.

Thanks for giving it a go anyway!

Well, I'm a 3rd year Physics Undergrad and this is a question for my Quantum Physics class, not Thermodynamics. I think that's why I have to use the equation above and in the derivation I have for that, Avogadro's number cancels out somewhere along the way. There's a section in my lecture notes...

Homework Statement Estimate the precise value for the specific heat of a nitrogen molecule at T=13.6K Homework Equations I'm pretty sure the correct equation is: Cp = (7/2)*R + R((hv)/(kT))2 *((e(hv/kT))/(e(hv/kT)-1)2 So R=8.314 J K-1mol-1 T=13.6K h=6.626*10-34m2kg s-1...

Ok, thanks so much for the help!

Well the alpha particle and the Th-228 have to move away from each other so the energy turns into kinetic energy. So if it isn't moving in the beginning, and momentum has to be conserved, then they move in opposite directions. So then since K = (p^2)/2m, the energy is divided according to their...

Does most or all of the energy get carried off by the alpha particle then?

Homework Statement (a) Calculate the disintegration energy when 232/92U decays by alpha emission into 228/90Th. Atomic masses of 232/92U and 228/90Th are 232.037156u and 228.028741u, respectively. (b) For the 232/92U decay in part (a), how much of the disintegration energy will be...

In an experiment to determine g using simple harmonic motion using a harmonic oscillator, a motion sensor and data logging equipment. I have all the variables but I can't figure out how to get S in the following equation: T^2 = ((4pi^2)/k)M + ((4pi^2)/k)S ...(1) I have a graph of T^2 (the...
