Atmospheric scale height of primordial Earth. The present-day Earth has an N2 and O2 dominant atmosphere with a mean molecular mass of 29 amu (atomic mass unit) and an atmospheric scale height of 8.5 km. It has been proposed that the atmosphere of the primordial Earth is composed mainly of hydrogen molecules, H2, which has a molecular mass of 2 amu. Assuming that the atmospheric temperature of primordial Earth is the same as that of today, what would the atmospheric scale height of the primordial Earth be? A. 17 km. B. 123.25 km. C. 61.625 km. D. 0.586 km

The vectors $v_1 = \begin{bmatrix} 1 \\ -2 \end{bmatrix}$, $v_2 = \begin{bmatrix} 4 \\ -13 \end{bmatrix}$, $v_3 = \begin{bmatrix} -1 \\ -3 \end{bmatrix}$ span $R^2$ but do not form a basis. Find two different ways to express $\begin{bmatrix} -10 \\ 35 \end{bmatrix}$ as a linear combination of $v_1, v_2, v_3$. Write $\begin{bmatrix} -10 \\ 35 \end{bmatrix}$ as a linear combination of $v_1, v_2, v_3$ when the coefficient of $v_3$ is 0. $\begin{bmatrix} -10 \\ 35 \end{bmatrix} = \begin{bmatrix} 1 \\ -2 \end{bmatrix}v_1 + \begin{bmatrix} 4 \\ 13 \end{bmatrix}v_2$

The average kinetic energy of a particle in a gas is given by $K = \frac{3}{2}k_BT$ where $T$ is the temperature. At room temperature, $T = 293.0 \text{ K}$, which particle has a longer de Broglie wavelength between a proton and an electron? Justify your answer by means of a calcu- lation. [4] 2. Electrons are accelerated from rest through a potential difference $V_0$, so that their de Broglie wavelength is 40 pm. Calculate the numerical value of $V_0$. [2] 3. Using $E^2 = (pc)^2 + (mc^2)^2$. For de Broglie waves, show that: (a) the group velocity is equal to $c^2/v_{ph}$ where $v_{ph}$ is the phase velocity. (b) the phase velocity is greater than $c$. [3] [2] 4.
