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)

The energy released by a nuclear fusion reaction is produced when

An charge with mass m and charge q is emitted from the origin, (x, y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
