Right, I've corrected that part using the energy of the first excited state and finding those x intersection points. However the integral I get still involves an error function, and I'm wanting to get a numerical approximation.

Homework Statement A particle in the harmonic oscillator potential is in the first excited state. What is the probability of finding this particle in the classically forbidden region? Homework Equations probability of finding particle = integral of abs[psi squared] [a,b] The Attempt...

I'm a senior and I'm in my fourth (and last) year in college. Traditionally I'm an A/B student, I haven't ever earned a grade in a course below a B. However, this quantum mechanics course I'm taking has me scared. I'm taking quantum mechanics using Griffiths as a textbook and my school curricula...

Homework Statement "A photon of energy E collides with an electron at rest. Calculate the maximum amount of Energy Ek that may be transferred to the electron. Make a graph of Ek versus E, labeling the scale in electronvolts. Homework Equations Transfer = Ek = E - mc^2*E/(mc^2 + 2E)...

I'm guessing the second block is hanging over the triangle i.e. it's hanging vertically downward. The way to solve for tension is to ask yourself two questions: 1.) If you removed the block hanging down vertically from the system - what would the tension be? What does this answer tell you...

2x + y = 1 if you subtract 2x on both sides you would get y = 1 - 2x Since in the basic form of algebra, 1 is a term and -2x is a term and terms can be read in any order provided you keep their sign y = 1 -2x = -2x + 1 y = -2x + 1 Now what would the slope and y-intercept be?

1.) problem statement Relativistic protons that have a certain speed "v" are selected by measuring the time it takes the proton to travel between two detectors separated by a distance "L". Each detector produces an electronic pulse of very short duration (LaTeX Code: \\Delta t << L/v) when a...

oh so my spacetime interval would then be (700^2-300^2)^1/2 = 632.455 seconds, taking c = 1 Thanks.

The unit works out to be in meters but my axis's are both in seconds.. I don't quite understand how this can be resolved or what this interval is even telling me.

Homework Statement on a spacetime plot (y-axis) = t (x-axis) = x find the spacetime interval between points (0,0) and (300,700) Homework Equations Interval = (c^2(del t)^2 - (del r)^2)^1/2 The Attempt at a Solution So I can see clearly my del t is 700 (700 - 0 = 700 ) but for the...

Wait, this I don't understand, if A is moving towards the observer by virtue of the train's movement, then wouldn't the distance between the observer and the point A be decreasing not increasing?

Homework Statement "Two firecrackers A and B are placed at x' = 0 and x' = 100 ns, respectively, on a train moving in the +x direction relative to the ground frame. According to synchronized clocks on the train, both firecrackers explode simultaneously. Which firecracker explodes first...

Homework Statement "A standing wave in the form of a string attached to a driven tuning fork is created. We then move the furthest boundary point to a node somewhere along the string. The node of course was originally at rest by definition. The string behind the node with the boundary point...

Homework Statement "The equation mx'' + kx = F0 * Sin (wt) governs the motion of an undamped harmonic oscillator driven by a sinusoidal force of angular frequency w. Show that the steady-state solution is x = F0 * Sin (wt) /(m * (w0^2 - w^2)) Homework Equations x(t) = xta(t) +...

Homework Statement My book defines the equation for energy of an RLC circuit to be E = 1/2 L I^2 + 1/2 Q^2/C In series the Quality factor is (L/C)^1/2/R My question is will these equations hold for an RLC circuit that is parallel. I.E. the Resistor is in parallel with the Inductor which is...
