Question: The image below represents two identical rigid gas tanks held at identical temperatures and pressures. Tank One contains oxygen gas ($O_2$) and Tank Two contains hydrogen gas ($H_2$). Which statement correctly compares the number of molecules in the two tanks? Items Gas pressure is the result of gas molecules colliding with the container wall $PV = nRT$ $H_2$ has smaller molecular radius than $O_2$ Sample mass divided by the molar mass equals moles $\mu = \frac{3.87 M}{m}$ A mole (n) is used to express the number of atoms or molecules in a sample The value of n is the same for both gases For gases, particle speed and particle mass are inversely related R is a constant value Reasoning Space to Build Argument 1 The volume, temperature and pressure are equal for both gases 2 $O_2$ has a greater molar mass than $H_2$ 3 so 4 Tank 1 contains a greater number of gas molecules than Tank 2. Conjunctions 1 because 2 because 3 because 4 so 5 so 6 therefore 7 therefore 8 and 9 and 10 and 11 but 12 but 13 but Required Conclusion 1 Tank 2 contains a greater number of gas molecules than Tank 1. 2 Tank 1 and Tank 2 contain an identical number of gas molecules. 3 There is no way to compare the number gas molecules based on the given information.

Growth spurt: It is generally known that boys grow at an unusually fast rate between the ages of about 12 and 14 . Following are heights, in inches of 10 boys, measured at age 12 and again at age 14 . Can you conclude that the mean increase in height differs from 5 inches? Let \( \mu_{1} \) represent the mean height at age 14 and \( \mu_{d}=\mu_{1}-\mu_{2} \). Use the \( \alpha=0.10 \) level and the \( P \)-value method with the TI-84 Plus calculator. \begin{tabular}{lllllllllll} \hline & \multicolumn{10}{c}{ Height } \\ \hline Age 12 & 57.8 & 68.3 & 63.0 & 64.4 & 58.2 & 59.7 & 60.2 & 63.7 & 60.2 & 62.7 \\ \hline Age 14 & 62.8 & 73.6 & 67.7 & 69.2 & 64.6 & 66.1 & 65.9 & 68.3 & 65.2 & 67.9 \\ \hline \end{tabular} Send data to Excel Part: \( 0 / 4 \) Part 1 of 4 (a) State the appropriate null and alternate hypotheses. \[ \begin{array}{l} H_{0}: \square \\ H_{1}: \square \end{array} \] This hypothesis test is a (Choose one) \( \square \) test.

17. An electron in an oscillating electric field is described by the Hamiltonian operator $H = \frac{p^2}{2m} - (eE_0 cos\omega t)x$ Calculate expressions for the time dependence of \(\langle x \rangle\), \(\langle p \rangle\), and \(\langle H \rangle\). 18. Solve the equations of motion you obtained in Problem 17. Write your solutions in terms of \(\langle x \rangle_0\) and \(\langle p \rangle_0\), the expectation values at time $t = 0$.
