I need help with all parts please!

11 1 point In terms of polarization, which of the following is true for most common light sources (e.g., the Sun, a light bulb)? The light is partially polarized The light is unpolarized The light is circularly polarized The light is naturally polarized Clear my selection 12 1 point An object is placed 100 cm in front of a lens of focal length 20 cm. A second lens is placed 15 cm past the first lens. The second lens has a focal length of 40 cm. The final image is real and upright. cannot be determined with the information given. O is real and inverted. O is virtual and upright. is virtual and inverted. Clear my selection 13 1 point A convex lens has focal length f. An object is placed at 2f on the axis. The image formed is located between 2f and infinity between f and 2f, O at f at 2 Clear my selection 14 1 point The critical angle for a beam of light passing from wate 48.8: This means that all light rays with an angle of incidence in the water that is greater than 48.8" will be totally transmitted. O partially reflected and partially transmitted. O totally reflected. totally absorbed by the water. Clear my selection 15 Faraday's Law relates the induced emf in a coll to the rate of change o Electric field through the coil. O Voltage across the coil. Current through the coil. Magnetic flux through the coil. Clear my selection 16 1 point The induced current in a loop when exposed to a decreasing magnetic field directly through it will flow in a direction that Alternates to stabilize the magnetic field. Has no effect on the magnetic field. Decreases the magnetic field even further. Attempts to increase the magnetic field. Clear my selection 17 1 point An emf Is induced in a coil due to a changing magnetic field. This induced emf is capable of; Creating a static charge on the call, Increasing the coll's inductance. Driving a current through the call, Permanently magnetizing the coil
