Hello there,
This isn't specifically homework, it is study. I'm having a difficult time trying to understand how to calculate/estimate partial decay widths, \Gamma[\itex], and Branching Ratios. I haven't found very clear information online so far. Here's just an example below that I'd like...
I think I need to determine it more accurately than just using my eyeballs. Later on in the problem sheet I've given, I am required to include damping forces, which will make it harder to determine period using the method you've described. I am required to modify the MATLAB program I've written...
I just realized this a second ago. Thank you, Chestermiller and D H, this is great help.
As per my original question, does anything know how I find the period of the oscillations? Do I just use a fourier transform of some kind in MATLAB to find the frequency and then use that to find the...
The way I initially wrote 5 and 6 here were typos, sorry. I used item 1 because that is basically what the initial acceleration is, as stated in the question: \frac{d^{2}x}{dt^{2}}=-\omega^{2}_{0}x, so I subbed in the angular frequency (\omega_{0} = 1) and x(at t=0)=1 to get my initial...
Sorry, I should have written the initial equation of motion as:
\frac{d^{2}x}{dt^{2}}=-\omega^{2}_{0}x
Basically, I forgot the 'x' on the LHS when I was writing the OP. This will mean that a = - 1 (I forgot to add the 'minus' sign), because x (t=0) = 1 and w = 0. The velocity remains v...
Homework Statement
Numerically determine the period of oscillations for a harmonic oscillator using the Euler-Richardson algorithm. The equation of motion of the harmonic oscillator is described by the following:
\frac{d^{2}}{dt^{2}} = - \omega^{2}_{0}x
The initial conditions are x(t=0)=1...

A quasi-3 level solid-state laser gain medium consists of a ground state manifold containing two energy levels within which a single electron can be promoted, with the second energy 10meV above that of the lowest level.

Homework Statement
The nuclei ^{41}_{21}Sc and ^{41}_{20}Ca are said to be a pair of mirror nuclei. If the binding energy of ^{41}_{21}Sc and ^{41}_{20}Ca is 343.143 MeV and 350.420 MeV, respectively, estimate the radii of the two nuclei with the aid of the Semi-Empirical Mass Formula...
P is the Radiation Pressure. It relates to the first law of termodynamics definition of work, PdV. Basically, I'm looking to derive Wien's law from the first law.
Can someone tell me how I can derive Wien's law, i.e.,
\lambda_{max} T = constant
where \lambda_{max} is the peak wavelength and T is the absolute temperature of the black body, using the equation,
P=\frac{U^{*}}{3}
where U^{*} is the energy density.
Note: I'm not looking for...

Consider a system that is initially in the state:
\psi\left(\theta,\phi\right)=\frac{1}{\sqrt{5}}Y_{1,-1}\left(\theta,\phi\right) + \frac{\sqrt{3}}{5}Y_{1,0}\left(\theta,\phi\right)+\frac{1}{\sqrt{5}}Y_{1,1}\left(\theta,\phi\right)

I have been stuck on the following question for a while now, particularly part B and C, and I'd like some help with it please. I've completed part A already. The Question:

For this whole question let T be a linear transformation from R^3 to R^3 with
T(1,0,0) = (2,2,2),
T(0,1,0) = (1,2,2),

Thanks very much for your reply.
So basically you're saying that physics/math students have greater problem solving ability than quant. finance students or CS students. In this regard, would it be better if I stayed in physics until I finish my Ph.D. and then make a transition into finance or...
Hey there,
I'm in second year of a physics/math degree. I've had some revelations over the past year and realise that I probably will not be interested in entering into the field of research or academia. I'm looking at the field of finance now (I hear that this is a common career path for...
I was having a discussion with a friend and I wanted to know if the following statement is true:
"calculus is advanced algebra and deals with curves (changing numbers), group theory is another branch of advanced algebra. The point is they are all algebra."
In a biased overstatement, I would say asking about the career options you can take after your physics degree is like asking exactly when 0.9999...(to infinity) will reach 1.
I'm majoring in Physics and I have about 32 hours (!!!) a week this semester between lectures, tutorials and labs. This is over 6 hours a day on average but that is spread over the entire day so I'm in university for about 9 hour every day on average, with 3 hours of breaks in between. On top of...
Unfortunately I can't change my major at all, however I can change my minor, just the system we have over here. We have to choose our major at the end of secondary school (high school). The only way I can do that is to drop out and reapply but that has financial implementations. I have to remain...
I was looking into trading or maybe financial analysis, however I'm not too sure yet. I'm only in first year of university and I'm just basically weighing up what I should be aiming for.
I was looking at University College Dublin or Trinity College Dublin for this grad programme (I don't...
