Determine whether the following statement is true or false. The inverse of squaring is finding a square root. Choose the correct answer below. A. The statement is true because if $c \ge 0$, then $\sqrt{c^2} = c = (\sqrt{c})^2$. B. The statement is false because if $c \ge 0$, then $\sqrt{c^2} = c \ne (\sqrt{c})^2$. C. The statement is true because if $c < 0$, then $\sqrt{c^2} = c = (\sqrt{c})^2$. D. The statement is false because if $c < 0$, then $\sqrt{c^2} = c \ne (\sqrt{c})^2$.

Problem 28 Spin 1 is placed in a constant magnetic field, $H = \omega \mathbf{n} \cdot \hat{\mathbf{S}}$, $\mathbf{n} = \frac{1}{\sqrt{2}}(\mathbf{x} + \mathbf{z})$. Given that at $t = 0$ the spin in the state $|\psi(0)\rangle = \frac{1}{\sqrt{2}}(|1;z\rangle - |-1;z\rangle)$, find the probability that a measurement of $S_z$ at time $t$ will find $S_z = 0$. Hint. Use $\hat{R}(\theta \mathbf{n}) = \hat{1} - i \sin \theta (\hat{\mathbf{S}}_\mathbf{n}/\hbar) - (1 - \cos \theta)(\hat{\mathbf{S}}_\mathbf{n}/\hbar)^2$
