Use the Ratio Test or the Root Test to determine whether the following series converges absolutely or diverges. $$ \sum_{k=1}^{\infty} (-1)^{k+1} \left( \frac{7k^4 + k}{3k^4 + k + 8} \right)^k $$ Select the correct choice below and fill in the answer box within your choice. (Type an exact answer in simplified form.) A. Both tests are inconclusive because r = and p = B. The series diverges by the Root Test because p = C. The series converges absolutely by the Ratio Test because r =

3. Show that the Hamiltonian $H = \frac{p^2}{2m} + V(x)$ is Hermitian, provided that $V(x)$ is real. 4. Solve the Schrödinger equation for a particle confined to a one-dimensional box with the origin at the centre of the box. The box extends from $x = -L/2$ to $x = L/2$. Determine the eigenvalues and the normalized eigenfunctions. 5. A particle is in the ground state of a box with sides at $x = -L/2$ and $x = L/2$. Very suddenly the sides of the box are moved to $x = -L$ and $x = L$. Calculate the probability that the particle will be found in the (i) ground state, (ii) first excited state, for the new set up.
