Problem 25P The mathematics of the previous problem can also be applied to a one-dimensional random walk: a journey consisting of N steps, all the same size, each chosen randomly to be either forward or backward. (The usual mental image is that of a drunk stumbling along an alley.) a) Where are you m

Electron in a well. Figure 24- 65 shows electric potential V along an x axis. The scale of the vertical axis is set by Vs 8.0 V. An electron is to be released at x ! 4.5 cm with initial kinetic energy 3.00 eV. (a) If it is initially moving in the negative direction of the axis, does it reach a turnin
