A particle of mass m is located in a box of length L and found to be in its ground state
A) what is the probability of finding the particle between x=0 and x=L/4
B) What is the expectation value for the position of the particle?
C)What is the expectation value <x^2>...
Consider a particle in a superposition of states given at time t=0 by Y(x,0)=C(y1(x)+y2(x)), where y1(x) and y2(x) are the stationary states with energies E1 and E2 respectively. if y1(x) and y2(x) are orthonormalized, what value of C is required to normalize Y(x,0)...
ok, that makes some sense, so since the position operator [x] is just x, then all of the functions are eigenfunctions...similarly, the potential energy operator [U] is just the potential energy function. In this case the function is zero so since its [U]=0 all the functions are eigen functions...
given the following functions:
Which are eigenfunctions of the position, momentum, potential energy,kinetic energy, hamiltonian, and total energy operators
A ruby laser emits light of wavelength 694.3 nm. If this light is due to the transition from n=2 to n=1 state of the electron in a box, what is the width of the box?

a projectile is launched at an angle \alpha above the horizontal, from the top of a vertical cliff of height h above the ocean. It strikes a distance d from teh base of the cliff. Show that its maximum height is given by H2 +(d2/4)tan2\alpha/(H+d tan\alpha) neglecting air...
an object of .4kg is attached to a spring with given spring constant 400 N/m. it is moving on a tilted table, that is at 30 deg from teh horizontal. The table is frictionless, but there is a dampening force -bv proportional to velocity. when the object is driven, the...
Is this a simple harmonic question or no??
a particle moves on the x axis under the influence of a force, proportional to its distance from the origin, attracting it toward the origin. The particle starts from rest @x=10cm and reaches x=5cm in 2 seconds for the first time...
so your tellin me that these functions are vectors? Ok i can dig it, so i take the derivative with respect to time and i'll have the velocity, take it again and i'll have the acceleration. That seems to be too simple, but i'll try it
ok but i'm not seein it? the block is on a ramp, so with the incline mg is straight down while the normal force is perpendicular to the surface of the ramp at angle theta. So i don't quite see how to solve for the velocity...
an object moves according to x=3m exp(-2/s t), y=4msin(3/s t), z=-5cos(3/s t) find the velocity and the acceleration.

I am unsure what this means, i am doing this for extra credit for my physics class in college(civil...
No, i understand the normal force is Fn(normal force) cos(theta). And as for the equations thats just my understanding of the forces on the block, the one set equal to (ma) is the equation for motion of my system as i believe...
a block(mass m), is sliding down a long straight ramp with angle theta, this block is undergoing frictional forces(mu) and air resistance proportional to the speed of the block. In its sliding the block reaches a terminal velocity. Determine the equation of motion and...
