Sorry, there was a mistake with my original entry. The function is not a derivative. I'm working on a physics experiment, where the data has a divergence. In my research I found that there is a functional of the form y=constant that is commonly used to fit this sort of divergence. Supposedly...

So far all I know is that a functional is a function that has a set of functions as its domain. So what does that mean? I have a functional that looks like dy/dx = a bunch of constants. What I'd like to know is how to take that and plot it. Can this be done?

If you have a rubber band wrapped around a cylinder, how can you tell the tension in the band? What parameters do you need to know?

I have a problem with a particle experiencing a central force towards some origin, as well as a gravitational force downwards. I've calculated the Lagrangian, and the equations of motion. Now I'm being asked to see if the system follows conservation of angular momentum. How do I do this? I...

You're right, that's not advanced physics, its simple DE. But that's not what I asked. For that equation to make sense, the exponent should be dimensionless. C*t is not. That's the part I don't understand

I'm working on a question where gas is leaking out of a container from a small pinhole. I have a differential equation dN/dt = (Constants)*N. I solved this to get an exponential. The exponent is that group of constants, which are A/2V*(kT/m)^1/2. Shouldn't the exponent have something to do...

How would you go about calculating the volume, pressure or temperature for the critical point in a phase plane? I know that there's a Clapeyron equation for finding the equation of the coexistance curve dP= L/TV dT, but can this be used to find the critical point? and if not, what will? I've...

I don't think that will help with anything. If it's an adiabatic process, deltaT will be zero.

I have in front of me an equation for energy in a system [ U=U(P,V) ]. I'm being asked to find "the equation of the adiabats in the P-V plane". What are they looking for? I know an adiabat is a system with no heat transfer, meaning that the energy of the system would equal the work done on...

How do you go about crossing two vectors if they are in cylindrical coordinates? I have one vector in the direction of R and another in the direction of theta. Can this be done?

How would I go about doing this problem? I have an infinitely long solenoid with a time dependent magnetic field inside. How can I find the E field? I've been trying something with Ampere's law, but I'm having trouble avoiding an infinite answer. Any insight would be appreciated. Thanks

I'm not overly familiar with GR, but I have heard that gravity is basically a result of the curvature of space. Its not an attractive force so much as its a consequence of traveling on a curved surface. But I've also read that observing cosmic microwave background hot spots leads to a flat...

I was missing constants if you were trying to find B. But I believe the original question was to find the line integral of B*dl

I don't think you have to do anything with that angle. I don't think Ampere's law specifies on the direction. I'm pretty sure the answer is just uI. This looks a lot like the question I'm working on. You're not in Senba's class, are you?

I'm working on a lab where I used LEDs of different wavelenths to record photocurrent they create when striking a metal. Using this data, i was able to find an equation relating the wavelength of the incident light to the current that is produced. My problem is that when I repeated the...
