Physics: Principles with Applications 6
Cars used to be built as rigid as possible to withstand collisions. Today, though, cars are designed to have "crumple zones" that collapse upon impact. What is the advantage of this new design?

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

Despite many attempts, the perbromate ion (BrO4 2) was not prepared in the laboratory until about 1970. (In fact, articles were published explaining theoretically why it could never be prepared!) Draw a Lewis structure for BrO4 2 in which all atoms have lowest formal charges.
