OTA 103642 please! series caps

I have a question that I need a little help with. A 5.0 uf capacitor is connected to a 3.5 uf capacitor, and both of them are connected to a 6 volt battery. 1) what is the charge on each capacitor? What is the voltage on each capacitor? 2) With the battery still connected, the 3.5 uf cap is accidentally shorted out. As ...continues

Electricity, Magnetism and Waves

Your company is designing a desktop-sized proton accelerator, using a 500MN/C superconducting magnet to hold the protons in a circular path. Estimate the maximum kinetic energy that your accelerator can give protons. Express your answer in the conventional particle physics unit of Electron volts, where 1eV=1.6x10^-19 J.(Assume ...continues

Electric field

An electric dipole is constructed out of two point charges of equal magnitude q and opposite signs, separated by a distance d, as shown in the attached diagram. Find the electric field at the point P. (the two charges are each a distance r from point P). Thank you!

induced emf

A two turn circular wire loop of radius .262 m lies in a plane perpendicular to a uniform magnetic field of magnitude .373 T. Now the wire is reshaped from a two turn circle to a one turn circle in .134 s. What is the magnitude of the average induced emf in the wire during this time in units of V?

magnetic flux

The magnetic flux threading a metal ring varies with time t according to 3at^3-bt^2, with a = 7.7s^-3m^2T, and b = 2.8 s^-2m^2T. The resistance of the ring is 2.3 Ohms. Determine the maximum current induced in the ring during the interval from t1 = -2.3 s to t2 = 7.3 s. Answer in units of A

Rectangular Coil

The plane of a rectangular coil of dimension 5 cm by 8 cm is perpendicular to the direction of a magnetic field B. The coil has 29.7 turns and a total resistance of 12.8 Ohms. At what rate must the magnitude of B change in order to induce a current of .227 A in the windings of the coil in units of T/s?

ac generator

An AC generator consists of eight turns of wire, each of area .0756 m^2, and a total resistance of 8.38 Ohms. The loop rotates in the external magnetic field of strength .35 T at a constant frequency of 59.7 Hz. What is the maximum induced emf? Units if V What is the maximum induced current? Units of A

inductor

The current in a 48.1 mH inductor changes with time as I = bt^2 - at. With a = 2.7 A/s and b = 3 A/s^2, find the magnitude of the induced emf at t = .992 s. Units of V At what time is the emf zero? Units of s

conducting rod

Consider a rotating conducting rod with length a. It is fixed at the end O and is rotating clockwise with angular frequency, omega. The rotation occurs in a region in which there is a constant, uniform magnetic field perpendicular to the plane of rotation. The magnitude of this field is B. What is the magnitude of the el ...continues

coaxial cable

A coaxial cable consists of a wire of radius 'a' surrounded by a concentric conducting sleeve of inner radius 'b' and outer radius 'c'. A current flows in the wire of radius 'a' out of the page; this current is spread uniformly over the cross section of the wire. An equal current flows in the opposite direction in the sleeve; ...continues
