They are chocolate chip, Sebastian's favorite kind. He briefly thinks that if he took all four cookies, Benjamin would never know. Then he remembers that the last time he did that, he had to sit in time out for an hour while Benjamin got to play in the pool with their dad. Sebastian decides to take only two of the cookies. Which stage in Kohlberg's theory is Sebastian in? a. conventional moral reasoning b. autonomous morality c. preconventional moral reasoning d. heteronomous morality QUESTION 27

In the Heisenberg picture, the observable $\hat{O}_H(t)$ satisfies the equation of motion $\frac{\partial}{\partial t}\hat{O}_H(t) = \frac{i}{\hbar}[\hat{H}_H(t), \hat{O}_H(t)] + (\frac{\partial}{\partial t}\hat{O}(t))_H$. Consider a free particle of mass $m$ described by the Hamiltonian $H = \hat{p}^2/2m$. i. Using the above equation, show that the position operator in the Heisenberg picture becomes $\hat{x}_H(t) = \hat{x}_H(0) + \frac{t}{m}\hat{p}_H$. You may use the relationship $[\hat{x}, \hat{p}^2] = 2i\hbar\hat{p}$ and the result of part 4(c). ii. Show that the commutator $[\hat{x}_H(0), \hat{x}_H(t)] = i\hbar t/m$. You may use the rela- tionship $[\hat{x}, \hat{p}] = i\hbar I$.
