One example of an electronic device that uses a large capacitor is a defibrillator that is used to reset the electrical activity in the heart during cardiac arrest. Using what you know about the purpose of capacitors, explain how a defibrillator uses a capacitor to deliver a strong electric current over a very short amount of time. Think of what happens during the process from the defibrillator being taken from its case to the moment when the electric shock is applied. Why do you think that a capacitor is needed for this process rather than a battery, which also is designed to store charge? Your submission should be about a paragraph in length and thoroughly discuss the defibrillation process, from a simplistic viewpoint focusing on the capacitor inside the device. You can support your written answer with diagrams or sketches if it helps you make your point.

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
