Bonus (each is worth 7.5 pts) a) derive the maxwell equations in time domain and express them in the phasor representation b) write the elcctric field and magnctic field components of an elliptically polarized plane emw in a lossless medium as an example (you can express them in formula form or as a specific emw with specific numerical parameters, such as medium characteristic parameters, amplitude, frequency, etc.) c) sketch the perpendicular and parallel reflections. you should show the incident, reflected, and transmitted wave correctly. give an outline on how to find reflection and transmission coefficients. (suppose two lossless media and oblique incident beam) d) what is brewster angle? sketch the necessary figures, explain the physical event, and derive its formula

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
