A arcular coil enclosing an area of 100 cm^2 is made of 200 turns orf Copper wire, the wire making up the coil has resistance of 5 ohm and the ends of the wire are connected to form a closed circuit, Initially, at 1.1T Uniform magnetic field points perpendicularly upward through the plane of the coil. The direction of the field then reverse so that the final magnetic field has a magnitude of 1.1 T and points down ward through the coil. If the time required for the field to reverse directions in 0.10sec, what is the average current in the coil during that time? ​

Follow these directions and answer the questions. 1. set up the ripple tank as in previous investigations. 2. bend the rubber tube to form a "concave mirror" and place in the ripple tank. the water level must be below the top of the hose. 3. generate a few straight pulses with the dowel and observe the reflected waves. do the waves focus (come together) upon reflection? can you locate the place where the waves meet? 4. touch the water surface where the waves converged. what happens to the reflected wave? 5. move your finger twice that distance from the hose (2f = c of c, center of the curvature) and touch the water again. does the image (the reflected wave) appear in the same location (c of c)? you may have to experiment before you find the exact location. sometimes it is hard to visualize with the ripple tank because the waves move so quickly. likewise, it is impossible to "see" light waves because they have such small wavelengths and move at the speed of light. however, both are examples of transverse waves and behave in the same way when a parallel wave fronts hit a curved surface.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.
