Question

6 Three long current parallel wies 12A.-8A) are a distance What is the magnetic force on ss-2m) 00-4 10-7 T A a 12 Is 7. A 12-turn square loop (0.2 m along a side, resistance-4 Ω) is placed in a magnetic field al shown. The magnitude of this field varies with time according to B-2-13f, whereis measured in s and B in T. (a) What is the induced current in the coil at 1.5 s? (b) Show the direction of L. 8. An LRC series circuit has a 56 Ω resistor, a 27 mH inductor, and a 78 μF capacitor. The circuit is driven by ac power source with rms voltage 110 V running at 60 Hz. What is the rms voltage across the inductor? 9. Two lenses is separated by a distance 10 cm. First lens is converging tfl-12 cm. Second lens is diverging lfi-10 cm. If one object is 20 cm from the first lens,find the final image 10. A 410-nm thickness film is coated on the surface of a glass. The indices of refraction of the film and the glass are 1.5 and 1.63, respectively. The surface of the film is illuminated from above at normal incidence with white light. There are TWO wavelengths of light strongly reflected in the visible light. If one λ-410 nm, what is the other?
