When subjected to a force of compression, the length of a bone (compression Young's modulus $9 \times 10^9$ N/m$^2$, tensile Young's modulus $3.4 \times 10^{10}$ N/m$^2$) decreases by $5.1 \times 10^{-5}$ m. When the same bone is subjected to a tensile force of the same magnitude, by how much does it stretch? $\Delta L = $

(4) Calculate the probability of being in the \text{``classically forbidden''} region of the $n = 0$ \\ and $n = 5$ levels of a harmonic oscillator. You will need to use numerical values of \\ the scaling distance $\alpha$ for the wavefunction, and the energy. Use $k_f = 516 \text{ Nm}^{-1}$ \\ and $\mu = 1.63 \times 10^{-27} \text{ kg}$ to determine $\alpha$, and $\hbar \omega = 5.94 \times 10^{-20} \text{ J}$ to determine the \\ energy of the levels.
