I will be trying to build an electric motor using superconductors and I have some general concept questions in regards to how the behavior might be different from ordinary wires.
1. The Meissner effect, expulsion of magnetic fields from the superconductor. If you construct a solenoid out of...
Thank you for your replies, do any of you know off hand if there is a way to mathematically derive a lower limit on the strength of the E-Field or Potential based on the assumption you only have H2O and electrode effects do not exist?
... if you try to observe the wave nature of a photon and then try to observe its particle nature... how do you know you are still looking at the same photon? don't they all look pretty similar...
I would say science is about measurement, all we can know is what we measured in a particular...
The cross product is defined, this definition does not change... The vectors used in the cross product can change, depending on what those vectors represent they change the meaning and understanding of what the cross product resultant vector is representing. In the torque case the cross...
I think this thread should be in the homework location... none the less you state with air resistance. My understanding is that the equation that describes air resistance is pretty complicated and is normally simplified to either linear or quadratic approximation. But Newtons laws of motion...
Reiterating what redbelly said. When you are looking at just the charge distribution on the conductor and saying there should be a potential difference there you are not looking at the net effect anymore you are then neglecting to include the external field that induced the charge separation in...
Well I thought F was used instead of dp/dt for the lower level physics texts that are not calculus based. Then as you go up levels in physics texts and math level you learn F is really representing dp/dt. side note, rate of change of momentum with respect to time is a bit of mouth full compared...
you wrote:
torque = force[i] X vertex[i]
Assuming X means cross product.
but Torque=r X F which does not equal F X r
Torque should be a vector and it is this vector you would rotate about. But be careful as forces/torques are only there during a collision (unless the cubes are moving in a...
I am currently re-reading an old textbook on thermal physics and they have listed the final result for calculating the Debye Heat Capacity as
C =9R(T/ThetaD)^3*Integral((z^4*e^z dz)/(e^z-1)^2, 0-->ThetaD/T)
But they fail to mention what the R in this equation is, Could some one please tell...
Well you already have your mind made up not to do Physics. So why not do Engineering. But I am sure as you got bored with the Physics classes you will get bored with the engineering too. Maybe you should just take some time away from it and revisit the issue at a later date and try the GRE and...
Hi,
When you have a high frequency high power alternating current, Can you use a regular wire to transmit the current or do you have to use a waveguide? Or some kind of combination?
Thanks.
This is not homework please do not move it to the homework section.
I need a pulse generator for an experiment I want to conduct at home... but I don't have that kind of money so I am trying to design and build one.
I am trying to see if the type of pulse generator I need is even feasible...
