File Preview Design a capacitor for a special purpose.
After graduating from medical school you and a friend take a three hour cruise to celebrate and end up
stranded on an island. While looking for food, a spider falls on your friend giving them a heart attack.
Recalling your physics, you realize you can build a make-shift defibrillator by constructing a capacitor from
materials on the boat and charging it using the boat's battery. You know that the capacitor must hold 100
J of energy and be at 1000 V (fortunately this is an electric boat which has batteries that are 1000 V) to
work. You decide to construct the capacitor by tightly sandwiching a single layer of Saran wrap between
sheets of aluminum foil. You read the Saran wrap box and fortunately they tell you that it has a thickness
0.01 mm and dielectric constant of 2.3. The Saran wrap and foil are 40 cm wide and very long. How long
is the final capacitor you build that saves your friend?

(The funnel is rotating around the vertical axis shown in the diagram.) There is no friction between the cube and the funnel but the funnel is rotating at just the right speed needed to keep the cube rotating with the funnel. The cube travels in a circular path of radius r, and the angle between the vertical and the wall of the funnel is 0. Express your answers to parts (b) and (c) in terms of m, r, g, and/or 0. (a) Sketch a free-body diagram for the cube. Show all the forces acting on it, and show the appropriate coordinate system to use for this problem. (b) What is the normal force acting on the cube? FN=mg58 (c) What is the speed v of the cube? (d) If the speed of the cube is different from what you determined in part (c), a force of friction is necessary to keep the cube from slipping in the funnel. If the funnel is rotating slower than it was above, draw a new free-body diagram for the cube to show which way friction…arrow_forwardCircular turns of radius r in a race track are often banked at an angle θ to allow the cars to achieve higher speeds around the turns.
