1. ### Thermodynamic derivation of heat capacity

yes, I know that there are several maxwell relations to get to the solution I just dont know how to apply them.
2. ### Engineering Thinking of a degree in nuclear engineering or health physics

what does health physics entail? I am interested in either nuclear engineering or Health physics but would like to get more detail on what it is that they actually do? Anybody know and wanna help out?
3. ### Thermodynamic derivation of heat capacity

Homework Statement cp=cv+TV?^2/? Homework Equations cp=T/N(\partialS/\partialT)p The Attempt at a Solution I have the equation, just not sure how to apply it? Any help would be appreciated
4. ### Probability of a Particle in a box location

ok so if the particle is supposed to be in between 0 and L/4 then i'm gonna get 4/L because it is 1/4 of the total length of the box...
5. ### Probability of a Particle in a box location

so how/where would i begin normalizing that??
6. ### Probability of a Particle in a box location

Homework Statement A particle of mass m is located in a box of length L and found to be in its ground state A) what is the probability of finding the particle between x=0 and x=L/4 B) What is the expectation value for the position of the particle? C)What is the expectation value <x^2>...
7. ### Superposition of states and orthonormalization

ok, i see, but the example in the book has the initial wavefunction given as Y(x,0)=Cexp(-|x|/x0) where C and x0 are constants, is it possible to get this function into a similar format??
8. ### Superposition of states and orthonormalization

that is not given, the only thing it asks for in this part of the problem is what value of C is required to normalize Y(x,0)...
9. ### Eigenfunction and Eigenvalue Confusion

its the operator...
10. ### Superposition of states and orthonormalization

Homework Statement Consider a particle in a superposition of states given at time t=0 by Y(x,0)=C(y1(x)+y2(x)), where y1(x) and y2(x) are the stationary states with energies E1 and E2 respectively. if y1(x) and y2(x) are orthonormalized, what value of C is required to normalize Y(x,0)...
11. ### Eigenfunction and Eigenvalue Confusion

\psi is psi, and i mean [x] times \psi would be [x]Acos(kx).
12. ### Eigenfunction and Eigenvalue Confusion

wait, so x is the operator and if it multiplies times Acos(kx) or Acos(kx)+iAsin(kx) then wouldn't it be the same as multiplying x(psi)???
13. ### Eigenfunction and Eigenvalue Confusion

ok thanks, i think I have bridged the gap in my knowledge, one more quick question though...in Acos(kx)+iAsin(kx) the i doesn't play a role does it? I mean its just like a negative sign??
14. ### Eigenfunction and Eigenvalue Confusion

ok, that makes some sense, so since the position operator [x] is just x, then all of the functions are eigenfunctions...similarly, the potential energy operator [U] is just the potential energy function. In this case the function is zero so since its [U]=0 all the functions are eigen functions...
15. ### Eigenfunction and Eigenvalue Confusion

Homework Statement given the following functions: y(x)= Acos(kx) y(x)=A sin(kx)-Acos(kx) y(x)=Acos(kx)+iAsin(kx) y(x)=A d(x-x0) Which are eigenfunctions of the position, momentum, potential energy,kinetic energy, hamiltonian, and total energy operators Homework Equations y(x) is...
