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

Consider a city that imposes a new pollution tax that increases the average cost (and price) of the good produced by a polluting industry by 4 percent and improves the citys environmental quality by 20 percent. The price elasticity of demand for the citys export goods is -1.50. a. The total output of
