A parallel-sided PLZT plate is positioned between two crossed Polaroid plates and the major faces of all three elements are normal to a parallel beam of monochromatic light (1 = 750 nm). The thickness of the PLZT plate is 1 mm and the electrodes, spaced 1 mm apart, are arranged such that a uniform electric field can be applied through the volume of the PLZT plate parallel to its major faces and at 45° to the transmission axis of each Polaroid plate. Calculate the voltage that must be applied between the electrodes to achieve maximum light transmittance through the system. Estimate the transmittance assuming 5% loss at each Polaroid surface and assuming that the PLZT element

We often think of friction and air resistance as forces that we want to minimize because they can hinder the motion of an object.  But they are not always undesirable, and in fact, can be an essential element in a machine or process. Identify one or two applications that depend on friction and air resistance.  Explain how friction or air resistance works in those situations and what would happen if there were no friction or air resistance.  Your initial post should be 75-150 words in length and is due on Sunday.

We are so confused half of us say that C is the correct answer and half say that D is the correct answer please help me with the explanation
