P7D.10 In the text the one-dimensional particle-in-a-box problem involves confining the particle to the range from x = 0 to x = L. This problem explores a similar situation in which the potential energy is zero between x = −L/2 andx = +L/2, and infinite elsewhere. (a) Identify the boundary conditions that apply in this case. (b) Show that cos() is a solution of the Schrödinger equation for the region with zero potential energy, find the values of k for which the boundary conditions are satisfied, and hence derive an expression for the corresponding energies. Sketch the three wavefunctions with the lowest energies. (c) Repeat the process, but this time with the trial wavefunction kx sin()

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
