Start by thinking what would make a successful egg drop. The point is to construct something around the egg to lessen the force experience by the egg when the impact with the ground occurs. How can the force of an impact be lessened?
One way to thing of it is momentum. The egg is falling and...
If you want to know where the particle is, you must make some sort of position measurement. If you want to know if the particle collides with the barrier, you must make some sort or measurement that will detect this collision. You must see that these two measurements are related. If you are...
The wave function does not collapse from a superposition of eigenstates until a measurement is performed. If the quantity being measured has a discrete spectrum, the wave-function will collapse to a single eigenfunction. If it has a continuous spectrum (like position in your case), the theory...
Additionally the Magnitude of the cross product is defined as:
|A x B|= |A||B| sin(theta)
not = |AB sin(theta)| or AB |sin(theta)| as you eluded to in your post.
When performing the dot and cross product the angle used in the formulas you listed is always the smaller angle between the two vectors. So an angle of 315 degrees corresponds to an angle of 45 degrees (360-315=45). And 225 corresponds to an angle of 135 degrees. This should help you answer your...
@malawi_glenn thank you for your reply. I appreciate you taking the time and clearly explaining this to me. Also sorry for posting in the wrong Section originally.
In my modern physics course we learn that different atoms and molecules have a unique set of allowed orbitals where it's electrons are allowed to exist. We then talk about how this corresponds to unique spectral lines emitted and absorbed by the different atoms/molecules. This continues onto...
hey thanks for your reply. However i am still not convinced about the electron...for example the following post: www(dot)physicsforums(dot)com/showthread(dot)php?t=184144&highlight=energy+levels+electron (sorry it wouldn't let me post a link to this topic even tho it is part of this forum?)...
hello i have a basic question regarding energy levels of electrons in atoms in bohr's model of the atom. From what I understand if an electron is in an energy level other than the ground state it can either absorb a photon equal to the difference of energy between its energy level and a higher...
i guess the answer should be for \frac{\partial^2 z}{\partial t^2} = v^2 * \frac{\partial^2t }{\partial u^2}
im not sure at all how to get this tho any help?
Hello I am trying to figure out the second derivative of
\frac{\partial^2 z}{\partial x^2} and \frac{\partial^2 z}{\partial t^2}
z(u) and u=x-vt
i found the first derivate of \frac{\partial z}{\partial x} to be
\frac{\partial z}{\partial x}= \frac{\partial z}{\partial u} *...
