Homework Statement
We suppose the nucleon density of a spherical nucleus where r<R1 is constant, and where R1<r<R2 the density linearly decreases to 0 at R2.
We call the surface nucleons (Number Ns) the number of nucleons contained in the volume R1<r<R2 and core nucleons (Nc) the number...
See this is on a french physics handout which has me bewildered as I'm not a chemist, but a little cross discipline never hurt.
I think the d,p refers to deuterium proton which decays to a neutron. I think i'll go see my Professor and ask exactly what he's asking and post it up as I cant seem...
Homework Statement
Express the energy (Or heat of the reaction Q) of the reaction (d,p) as a function of the binding energy of deuterium and the binding energy of the neutron captured by the target.
Homework Equations
Bn / A ≈ 8 MeV
Bn = Binding energy, A = Atomic Number
Q =...
ah balls your right, ive been looking at this question too long. I had to translate it from french as well which probably isnt helping. I'll take a nap and come back to it later.
but upto L=r m v sin theta is correct and v = r dθ/dt right, and theta being a constant means sin theta is also, so...
aha got it, thankyou,
\vec{r} \times \vec{p} = \abs{{r}}\abs{{p}}sin\theta
using dx/dt = sin (x) dθ/dt and p =mv
we arrive at
L = r mv sin θ
L = r mv dθ/dt sin x
where x is actually ⃗ux
so we get L = r mv dθ/dt sin ( ⃗ux)
I think this is correct, thankyou zachzach
Theta is the angle between the x-axis and r (as the electron goes round).
Am I right in saying that it should be the magnitudes on the right hand side of your suggestion as opposed to vectors i.e.
\vec{r} \times \vec{p} = \abs{{r}}\abs{{p}}sin\theta
as then that may help me.
K.E max =eVstop = h(f-f0)=hc/λ - y (Work function)
where f is freq, f0 is cutoff freq
the work function (y) can be related
f0 = y/h = c/λ0
hope that helps
The angular momentum of the Bohr atom is ⃗L = ⃗r× ⃗p
Let the Oz axis of the unit vector ⃗uz be determined by the relation L = L⃗uz, in which L stands for the magnitude of the angular momentum vector ⃗L .
(Basically L is in Positive z axis)
We specify the position of the electron within its...
