Chapter 9, Problem 9.2CYU
Check Your Understanding Circuit breakers in a home are rated in amperes, normally in a range from 10 amps to 30 amps, and are used to protect the residents from harm and their appliances from damage due to large currents. A single 15-amp circuit breaker may be used to protect several outlets in the living room, whereas a single 20-amp circuit breaker may be used to protect the refrigerator in the kitchen. What can you deduce from this about current used by the various appliances?

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?
How do I plot the force F in Matlba (of gravity pulling on the masses) versus spring displacement, and fit the data with a linear function to find the value for the spring constant. To get a linear fit, use polynomial order 1. Report the value of 'k' from the fit.
What code is used?

- PROBLEM 2 A cube of mass m is placed in a rotating funnel. (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.

Min Min’s arms are large springs, with a spring constant of 8.53 ⋅ 10^3 N/m, which she uses to punch and fling away her opponents. Min Min pushes her spring arm against Steve, who is not moving, compressing it 1.20 m as shown in figure A. Steve has a mass of 81.6 kg. Assuming she uses only the spring to launch Steve, how fast is Steve moving when the spring is no longer compressed? As Steve goes flying away he goes over the edge of the level, as shown in figure C. What is the magnitude of Steve’s velocity when he is 2.00 m below where he started?arrow_forward
