3. In dragging a large piece of concrete form a construction site in a ravine, the concrete does not follow the cable but moves along a path at an angle to the cable. The cable is pulling with a force that is given by $\vec{F} = (3, 1, 22)$ kN and the concrete moves a short distance $\vec{d} = (1, 0.3, 4)$ metres (the concrete initially starts at the origin) over which the force can be assumed to be constant as the crane which is controlling the cable shifts to maintain the magnitude and direction. a. What is the work that actually goes into moving the concrete block? b. What is the angle between the applied force and the direction the concrete is moving?

Which of the following statements explains the intracellular localization of ProteinX? The nuclear envelope and ER are contiguous - the same continuous membrane bilayers. Therefore ProteinX can easily move between the nuclear membranes and ER membranes. The signal sequence for insertion of proteins into the rough ER membrane bilayer is cut off by signal peptidase enzymes. Therefore, some ProteinX localizes to the ER and some remains in the cytoplasm. Because ProteinX is a transmembrane protein, it contains amino acids with hydrophobic side chains. Therefore, it can partition into any cellular membrane by liquid-liquid phase separation. The ER juxtaposes the nuclear lamina which is formed from intermediate filaments and is part of the cytoskeleton. Therefore, ProteinX localizes to both the nuclear envelope and actin cytoskeleton.

3. In this problem we have a function defined recursively by: g(0)=1, g(1)=2 and g(n+2)=2 g(n+1)+4 g(n) for all integers n?0. Compute g(0), g(1), g(2), g(3) and g(4), by hand. Compute g(1000) using a computer- again, you must explain the calcula- tion. Write g(n) = 2<sup>n</sup> f(n). Compute the first few values of f. You should get 1, 1, 2, 3, 5.... This should be a familiar sequence. Iden- tify the sequence and prove your result.

3. (10 pts) Let $\psi_1$ and $\psi_2$ be two solutions of the time-independent Schrödinger equation (TISE) with energies $E_1$ and $E_2$, respectively, where $E_1 \neq E_2$. Is $\psi = A \psi_1 + B \psi_2$, where A and B are nonzero constants, a solution to the TISE? Explain your answer.
