Hi all I was wondering if i could get some help with this.
[b]1. I need to be able to solve a second order differential equation,
[b]2. d^2(y)/dx^2= c/x
where c is an arbitary constant.
I was thinking that the solution would take form of a trigonometrial eqauation, would this be...
In Quantum Mechanics the one of the constraints on the wavefunction is that its derivative is continuous, what I have a problem with is that I have forgotten what this actually means in terms of an equation.
ie
[tex] \frac{d\psi){dx}=?[\tex]
This is driving me nutty and looked on the...
They want to make ice drink glasses if i have understood what they said. What you have given is just for basic ice formations. I think
I presume the person in question is using molds to shape the ice into glasses. In which case slowly cooling down the water from room temperature to freezing...
I think you will need to freeze the water very slowly in order to make sure it is clear, if you have ever noticed when messing around with liquid nitrogen if yo put a bottle of water into a bucket of the stuff, the ice you get out of it is "cloudy"
if you can try freezng it by starting at...
So therefore am I right in saying that,
\sigma=\frac{ \sigma'}{ (1+\alpha\lbrackT-T'))
Which implies that conductivity will decrease with temperature as long as alpha is less than 0
by the way for 304 steel alpha is 0.00172K^{-1}
Thanks for you inputs!

p.s why won't...
I am struggling to work out out whether the conductance will increase or decrease with an increase in temperature. This I know sounds so basic yet i can't grasp something. I know that resistance increases with temperature so I would assume that conductivity will decrease. However a formula I...
I just need see how the magnetic permeability of a piece of steel will change with a change in temperature. The reason why I need this is so that I can see what happens to the eddy current penetration depth when the material is being heat treated
I already know that the electrical...
Basically I have a pointer that starts at a particular reference point on a circle with cartisean coordinates,this pointer then moves around the circumference of the circle with an angle theta, the arc length is known but what I need to find is the change relative to x and y.
I know that the...
How would one derive the hamiltonian for a particle moving in a potential in the x direction whilst also rotating with an angle of theta??
I have tried deriving it the same way as the TISE using the angular momentum operator in 2d space but to no avail
basically the particle is moving...
I have a formula to solve, which I am having trouble solving, it is a differential equation fo sorts
\int{\frac{1}{m\log(m/mo)}{dm}=\int{\frac{1}{t}}{dt}
could someone help me solve the indefinite integral of such an equation!
the m multiply of the right handside is suppose to be dm and...
