Yes that makes sense, thanks again. You've been very helpful so I am going to push my luck and ask if you have any criticism of my logic for part b)?

Ok great, thanks. That has cleared it up for me - but just to fully make sure I have another hypothetical for you if you don't mind: Now we have one thin sheet and one cube, again the same type of metal. The front surface areas of both are equal which means the same amount of radiation is...

So let's assume they have been left in the sun for a long time and are in equilibrium. Each sheet will be at the same temperature right? But the amount of heat hitting each sheet (therefore the amount of heat lost to the surroundings) is also the same. So the air on the surface of each sheet...

Actually thinking about it a bit more, for a) if the sheets have the same dimensions therefore the same exposed surface area, would the amount of heat Q hitting the sheets be constant? Because the same amount of radiation will be hitting each one? Edit: I think I'm confusing myself. The...

These are questions I've made up to try and wrap my head around the topic, so the theory within the questions themselves might be flawed. 1. Homework Statement There are a number of metal sheets that are similar in every way except they each have slightly different masses. The temperature of...

I think I may be wrong about the electric quadrupole moments, it's possible that only protons contribute to Q. So because the only thing that changes with oxygen isotopes is neutron number Q will be 0 for all of them? EDIT: scratch that neutrons do actually contribute as they attract the...

Could somebody check if I have done this correctly please? 1. Homework Statement Draw the shell filling for oxygen isotopes and make predictions of their nuclear spin, parity, magnetic moment and electric quadrupole moment. Homework Equations Magnetic moment μ = gj j μN Electric quadrupole...

Forgot I had posted this question. Thanks!

Homework Statement Write the equations for neutron and proton fusion to form deuterium and for deuterium photodissociation. Homework EquationsThe Attempt at a Solution There is plenty on proton-proton fusion to form deuterium, but not much on proton-neutron. Is it simply p + n -> D ? Is...

Great, thanks for the help.

I'm pretty sure we'd only be working with the first one, the Nilsson diagram looks more advanced. Going off the first diagram it looks like our lone neutron would be in the 1f\frac{7}{2} shell where nuclear spin j = \frac{7}{2} and parity = (-1)3 [to the power 3 because it is in the f shell] =...

Homework Statement Use the shell model to determine the parity and spin assignments for all the stable isotopes of calcium. Homework Equations n/a The Attempt at a Solution The stable isotopes seem to be 40Ca, 42Ca, 43Ca, 44Ca, 46Ca, and 48Ca I believe all of those isotopes except 43Ca are...

Hmm I think I may have to post the question in full. My original post is just a small part of a bigger question (about Gauge transformations) so I am probably going about it wrong.

Sorry it is a vector. I was trying to mimic exactly how it is written in front of me.

Homework Statement I need to find Λ using the equation below (I think). Homework Equations A [/B]+ ∇Λ = 0 where A(x,y,z,t) = B\begin{pmatrix} x+y\\ x-y\\ 0 \end{pmatrix} The Attempt at a Solution Is this at all possible?
