Aplane emw with an whose characteristic values are e, reflection and transmission coefficients, c) find electric field and magnetic field components of the reflected field, d) find the power components of the reflected and transmitted wave clectric field component given by e = a,2 x 10-3e iz is propagating through a medium 4 and a, 1 in the normal direction. a) find its magnetic field component, b) find 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 electric field and magnetic field components of an elliptically polarized plane emw in a lossless medium example (you 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 specific emw with specific numerical parameters, such express them in formula form or as a as an can emt constants you may need are given as follows: 10 -9 c = 3 x 108ms1, o ho4t x 10-7hm"' fm1 8.854 x 10-12 fm1, 30m 1.2566 x 0-6hm-1, ηο 1 120π ω~ 377ω

How does convection affect our atmosphere? our layers of earth? our oceans?

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.

What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. wind turbines can kill birds that fly through the rotors. wind turbines are built too close to major population centers. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
