like what kp said, mechanical and metabolic work is completely different...technically speaking if you're talking about putting a stack of pallets on a cart and moving the cart some distance x, the total mechanical work done by you to move the cart 50 ft, 50 m, or 50 km is the same; 0...
Interesting to think about.
Modern Physics considers light as either a particle or wave, whatever fits the situation. Maybe this is one of the times where there is only an explination in the wave form?
Ok...I've struggled with this.
Let's say I'm dropping a mass from height h from the Earth's surface. Since I'm considering this as a non-inertial reference frame, I understand that there is an easternly deflection. I've done the calculation and end up with...
what you really need to remember is since you considering a massless pully, all it does is change the direction.
Draw your free body diagrams for each box, nowhere should you have a FBD with a pully involved (that was what always got me). Look at the force(s) acting on your system. Try to...
exactly. Even more cool is the fact that they don't even have to be [-1,1]/[1,-1]! They could be anything you want as long as a1=-a2 or -a1=a2! It could be [4,523,231,-4,523,231] or [-87,87], the possibilities are endless! Math is cool!
I don't have any equipment set up to see if the lattice is correct or not, but we do have the equipment I believe. Was hoping that I wouldn't have to go to those lengths.
The experimental setup is simple enough, just an electronic scale, about 20 styrofoam cups, a magnet and a ring stand. I...
If you're talking about Young's Double Slit experiment the usual explination is photon wave interference. The alternating light and dark areas are from constructive and destructive wave interference of the propogating photon waves from each slit. I'll try to draw and post a picture later if...
Hey everybody, just wanted to know if anyone had any experience with superconductor fabrication? I know the whole crystal lattice structure thing is more chemistry than physics but I figured I could post in both places.
Anyways, I am currenty trying to fabricate a 1-2-3 YBCO superconductor...
I'm a little confused with your methodology...I believe it's the T matrix that is throwing me off. Why is there an 'm' in the vector? Are you multiplying an identity matrix by 'm' just to get rid of the 1/m in the omega value?
If my understanding is correct it seems what you have done is fine...
The way I would do this problem is to first assume a spherical Earth for simplicity. Next draw a circle on a piece of paper, this will be your cross sectional area of the earth. Draw a line from the center of the Earth to equator, this is your Earth radius(this is only for reference). Now...
