In THE THEORY OF REALMATERIALS(Annu. Rev. Mater. Sci. 2000. 30:1–26), Marvin L. Cohen states that "Because charge transfer reduces the covalent component of a heteropolar bond, B0 is also reduced." Can you explain that connection between charge transfer and covalent component of a...

A ball is thrown into the air from ground level. After a time t = 2 s, the ball has traveled to a position x1 = 27 m to the right of and y1 = 10 m up from where it was thrown (at this time, the x and y components of the ball's velocity are still positive). The axes show the x and y directions to...

The one thing that is NOT identical for different particles in a state is the z component of spin, having a probability of being positive or negative. So when interchanging particles how do you handle the z component of the spin, it simply can't be interchanged along with the position and...

Hi everyone I have a little problem in understanding the trasformation of vectors component when passing to a different coordinate system (abbreviated CS). Theory says that the components of a vector in the first CS x with component (V^0,V^1,...,V^n) will transform changing CS according to...

Hi there, I'm really ashamed of doing this stupid question but I really need help with this thing. And, even if it's simple, it's not homework. I have a point P=(x,y,z) with velocity v=(vx,vy,vz) how can I determine the radial component of the velocity? My answer is that...

For an arbitrary vector, what is meant by tangential and normal component of the vector?

In the solution manual (which I never trust) the tension vector of the rope that emerges from point A only has a vertical component when calculating the sum of all moments on joint C. I disagree with the solution manual, since this vector also has a horizontal component, and if you calculate its...

Component to VGA schematic?? Anyone know where i can find a schematic for a component to VGA adapter? A friend is looking to make one so he can use his ps3 on his monitor but says most of the store bought ones are quite expensive and have lots of extra features. We are both engineering majors...

Which component E or B of an electromagnetic wave is responsible for visible effect?

Given that a photon or neutrino creates a gravitational effect, and given that the CMB, microwave photons emitted 13.8 billion years ago are still around in the universe, then it would follow that ALL photons or neutrinos that have not since been captured should also still be present in the...

Hi hope someone could help me understand the workings of electronic components. I think I am right in saying that all electronic components require energy for them to function. If you connect a battery to the component to supply the energy then this is supplied from the electrochemical...

How do you calculate the stress in a cantilevered beam with a point load at the free end where the load has a large horizontal component loading the beam in tension as well as bending from the vertical component? And the beam bends far enough so it's slope will match the slope of the load at...
