I have a very basic question regarding the nucleus. I understand why you can only have a limited number of protons within the nucleus - more and more protons within the nucleus will increase the coulomb potential and cause the nucleus to be unstable. But why is this so for neutrons? Why...

A Mass is oscillating on a spring, with a normal equation of motion being: x(t) = xmax sin(wt) Were also given that the energy equation is E = 0.5mv^2 + 0.5mw^2 x^2 Now, we need to find the probability P(x,deltax) of finding the mass in a small region of size delta x. I really have no idea...

Thanks for the input, but what good would the radius of convergence give me? Couldnt I just truncate the expansion, and solve for the difference between g(r)?

Hey Everyone. I'm ALMOST finished this problem... To spare you the long story, I need to take the difference between an gravitational acceleration, and the same gravitational acceleration at a slightly larger height. The two functions are a(r) and a(r+d), where d is very small Now... VERY...

Ok, well... i would get an eigenvalue of 1, with a multiplicity of 3. Alright, so when solving for my eigenvalues, by plugging 1 into my matrix A-(lamda)I ; i would just be left with 0's. How can i get eigenvalues from this?? I appreciate your help by the way...

Hey guys, I know its possible to diagonalize a matrix that has repeated eigenvalues, but how is it done? Do you simply just have two identical eigenvectors?? Cheers Brent

Hey everyone, I need to prove something explictly, problem is, i don't know where to start. In orbits, we can show that the motion of 2 bodies interacting with each other only by central forces can be reduced to a an equivalent one-body problem. This is by using a Lagrangian, and by...

thanks a lot for your help, PS, how do i type that script you use for your reply?

Hey everyone... I think I am not picking up on something here... The rate of heat flow across a slab is: P = (k*A*T)/D where k is the thermal conductivity of the medium, A is the cross sectional medium and T is the temperature...

the problem is ( 12 + 5xy )dx + (6 (x/y)+ 3x^2)dy =0 and it says, find an integrating factor of the form (x^n) * (y^m), and solve the equation... thanks sweetie steph

Hey everyone, I need to find an integrating factor of the form x^n*y^m, to solve a differential equation i have... however i do not know the process to solve for an integration of this form.. .any help?? Thanks Steph

Hey everyone, I'm not sure where I am going wrong here... I need to find the 3 roots of the following equation: x^3 - (6.2)x^2-11x-5=0 and i need to find the real roots using the technique of iteration. I understand this technique, however I am not sure which values i should start off...

Hey, I have a problem with an RLC circuit. It consists of a resistor in series, followed by another resistor, capacitor, and inducer, all in parallel. The question is asking for what frequency (its an AC circuit), is the current through the inducer the same as the resistor (the one in...

Hey guys. I have a lens problem: A lens has a power of 300 dipoters, and a radius a of 2 mm. An object is located just beyond the focal length to get high magnification. The space between the object is filled oil with an index of refraction 1.4. Estimate the resolution for 500 nm light...

Hey guys, I have this problem.. When two capacitors.. (different) are in parallel across a 10.0 volt rms, 1.0 khz oscillator, the currrent is 545 mA . When the same capactiors are in series.. its 126 mA. What are the values of the two capacitors... Alright.. now... The formula when its in...
