Create a Simphy simulation as the video below shows. Q2a Give the bob a small displacement (~<15°). From your data, measure the period of oscillation. Compare the experimental results with the theoretical ($T = 2\pi \sqrt{\frac{l}{g}}$). Experiment with different lengths and masses (the mass has no say in this, but it's worth checking.) Q2b Repeat the previous run for a greater displacement; e.g., ~70° or so. Does the observed period match the theoretical? Q2c What would your answer be if someone asked you, "Does the initial displacement have any effect on the period of any oscillation"? Q2d Describe what happens to the bob's total acceleration when the oscillation amplitude is at maximum and at zero, respectively. Provide a scientific explanation for the material mentioned in Theory and particularly for the forces at play. Q2e From your observations, describe what happens to the kinetic and gravity potential energy during oscillation. Plot these energies as a function of time and show that total energy is always conserved.

3) For a linear polymer molecule, the total chain length L depends on the bond length between chain atoms d, the total number of bonds in the molecule N, and the angle between adjacent backbone chain atoms $\theta$, as follows: $L = Nd \sin(\theta/2)$ Furthermore, the average end-to-end distance for a series of polymer molecules r is equal to $r = d\sqrt{N}$ A linear polyethylene has a number-average molecular weight of 300,000 g/mol; compute average values of L and r for this material.

Calculate the theoretical cell potential of the following cells. If the cell is short-circuited, indicate the direction of the spontaneous cell reaction. a. Zn|Zn$^{2+}$ (0.1100 M)||Co$^{2+}$ (2.81 \times 10$^{-4}$ M)|Co ($E_{Zn^{2+}/Zn}^{0}$ = -0.763 V, $E_{Co^{2+}/Co}^{0}$ = -0.277 V) Cell potential = V The reaction will proceed spontaneously b.
