Use the ratio test to determine whether $\sum_{n=30}^{\infty} \frac{6^n}{(2n)!}$ converges or diverges. (a) Find the ratio of successive terms. Write your answer as a fully simplified fraction. For $n \ge 30$, $\lim_{n \to \infty} \left| \frac{a_{n+1}}{a_n} \right| = \lim_{n \to \infty} \frac{3}{\square}$ (b) Evaluate the limit in the previous part. Enter $\infty$ as infinity and $-\infty$ as -infinity. If the limit does not exist, enter DNE. $\lim_{n \to \infty} \left| \frac{a_{n+1}}{a_n} \right| = 0$ (c) By the ratio test, does the series converge, diverge, or is the test inconclusive? Converges

Question 1 (25 marks) a. A small house needs 2.4kWh per day, all of which is used in the evening between the hours of 7 to 11pm. Using only 12V batteries, calculate the minimum rated Ahr of battery storage required to supply the load if the battery maximum depth of discharge is 60%. Assume battery temperature is 25°C. b. With the aid of a well labeled diagram, explain the principle of operation, from resource to electrical power, of a PV module. c. How does shading impact on I-V curves of a PV module with and without a bypass and blocking diode. d. Imagine a space station with a solar array measuring 10 meters by 10 meters. In full sunlight, how much solar energy is impinging on the array? If it can be converted to electrical energy at 28% efficiency, how much power is generated (in W)? [8 + 5 + 5 + 7 marks]

5. Consider a particle in 1D infinite potential well, and estimate the effect of the first order relativistic correction $hat{H}prime = -frac{1}{8}frac{hat{p}^4}{m^3c^2}$ on the energy level of the system using first-order perturbation theory. Is there an energy where you expect the perturbation theory to fail?
