Part I. WORD PROBLEMS. Answer the word problems with complete solution. Use GRESA method.

Solve the following problems. Box your final answer. 1. A 25.0 m metal rod moves at a speed of 5 m/s perpendicular to a magnetic field of intensity 1.4 T. Find the resulting potential difference at the ends of the rods. 2. A square loop with 5 cm sides is perpendicular to a uniform field 150 mT in intensity. If a third of this flux remains every 0.010 s, what is the average emf induced?1. The diagram below shows two light rays emanating from the top of the object and incident towards the mirror. Describe how the reflected rays for these light rays can be drawn without actually using a protractor and the law of reflection. 2. A 2.80-cm diameter coin is placed a distance of 25.0 cm from a convex mirror that has a focal length of -12.0 cm. Determine the image distance and the diameter of the image. 3. A magnified, inverted image is located a distance of 32.0 cm from a double convex lens with a focal length of 12.0 cm. Determine the object distance and tell whether the image is real or virtual. 4. Briefly discuss how near sightedness is corrected using a lens. Support your discussion by constructing a ray diagram
