Thank you for the speedy response. :smile:

Hi everyone, I have the following question When a positive pion interacts with a proton, a kaon can be produced, along with another strange particle, as shown in this equation \pi^++\textrm{P}\longrightarrow \textrm{K}^++\textrm{X} Circle the type of interaction shown...

Hi there, I am a teacher and will be teaching the topic of alternating current soon. I have not taught this before and have certainly not studied this in many years so I am trying to get a full understanding and am looking for a bit of clarification. So I know that the current supplied by the...

I used a simulation from PHET, they have such great simulations. It was the motion and forces basics one. I had one of the students come up to have a go at changing all of the variables and moving everything around while I explained what was going on, which was good fun. Then I finished with a...

Hi everyone, thanks for all the great tips. Just to neatly tie this off I thought I'd let you know that I got the job. Thanks again.

Hello, I am about to have my first ever job interview for a teaching role, I am not even an NQT yet, I am still on my PGCE. The school I am being interviewed for are among the top grammar schools in the country and obviously have very high standards. I am doubtful I will get it as I am so...

The students are 13-14 years. The true or false will be an activity in which the students use small white boards to write on and to hold up the answer to each question. I will then explain why the answer is either true or false. Thanks.

Hello, I'm a trainee teacher and I'm delivering a lesson with a practical where the students find the densities of various objects. I want to end the class with 8 to 10 true or false questions about density which test misconceptions on density. The one I have is Is a dense object always heavy...

Yeah I figured that out, I was being an idiot. Thanks for the help though.

Hello, My problem is as follows I've tried differentiating to find the maximum and I've tried plotting E against m_{\chi} for a range of values and this did not suggest a maximum at m_N = m_{\chi}. Could someone explain why it is the case that the energy transfer is maximum when these masses...

Hello everyone This is sort of a geometry problem. I'm sure it has an easy answer but it just won't come to me. Here's my problem A close packed colloidal aggregate of smaller spherical colloidal particles can be thought of as small spheres within a sphere. I have the relationship...

Hello, In my problem I need to We are advised to create the Cooper pair box Hamiltonian in a matrix form in the charge basis for charge states from 0 to 5. Here is the Hamiltonian we are given H=E_C(n-n_g)^2 \left|n\right\rangle\left\langle...

Thanks, that was helpful.

Sorry, I should have referenced that better, this is a better link to follow http://lambda.gsfc.nasa.gov/product/map/current/map_bibliography.cfm and the paper where the plot came from is called Nine-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Cosmology Results Hinshaw...

Hello, I have to estimate some values from a plot (shown in the attachment). The trouble is I'm not sure how to read one of the scales could someone please explain the nature of the scale along the top frame, the angular scale, i.e how it is spaced. One of my aims is to estimate which angle...
