Question 4 (18 marks) (a) During a Physics Lab experiment, 1 st year SFY students analyzed the behavior of capacitors by connecting two capacitors to power sources. In one part of the lab activities, students connected a 2.50 µF capacitor to a 746 V power source, whilst connected a second 6.80 µF capacitor to a 562 V source. Once these capacitors are charged, they are then removed from the power sources and are interconnected by connecting the two positive plates (of the capacitors) together, and the two negative plates together. Determine the potential difference and charge across EACH capacitor. (12 marks) (b) In the second part of the lab activities, students charged another capacitor () using a 165 V source. Once charged, the capacitor was then removed from removed from the source and then connected to another capacitor () which was initially uncharged. If the students measured the final potential difference across each capacitor to be 15V, determine the value of (). (6 marks)

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
