- A 10.0 MHz magnetic field travels as a TEM wave in a fluid where the propagation velocity is 1.0 x 10^8. The amplitude of the wave drops by 50% of its initial value over a distance of 5.0 m in the fluid. What is the phase coefficient of this wave? # 2nx 10^5 rad/s # 5nx 10^5 rad/s # 10nx 10^5 rad/s # 20nx 10^5 rad/s # 100tx 10^5 rad/s # 200tx 10^5 rad/s # none of the above2: A/A transmission line of electric length 1 = 0.375 A, and operates at a frequency of 1 GHz, is terminated in a load 50-j102. The line parameters are (L= 400 nH/m), (C = 75 pF/m), (G= 15pU/m) and R = 40 mn/m, assume the Vg = 5V and Zs=20 2. Find the following for the lossless case transmission line: impedance ZL 1. The characteristic impedance (Zo) and the reflection factor at the load terminal ₁. 2. The propagation constant (y), Attenuation Coefficient (a), Phase Constant (B) and the phase velocity (vp) 3. Input impedance Zin and at the input terminal lin 4. The average power at input the transmission line Pin (Pa) and the average power delivered to the load PL(Pav). 5. If the condition of the line above is not in lossless case, prove that it case is in distortion-less.32. An alternating current generator in the United Kingdom generates current with a frequency of 50 Hz. Suppose that initially, the current is at its maximum of 12 amperes. If the current varies in simple harmonic motion over time, write a model for the current I (in amperes) as a function of the time t (in seconds). The angular displacement 0 (in radians) of a pendulum swinging through a small angle with limited air resistance and internal friction can be approximated by the simple harmonic motion models 0 = a sin ot or 8 = a cos ot. The period T (time required for one back-and-forth swing) is given byT- 27 where L is the length of the pendulum and g is the acceleration due to gravity. The maximum angular displacement is |a| and positive angles are taken to the right of the center position. Use this information for Exercises 33-34.

- Large quantities of dust should have been left behind after the creation of the solar system. Larger dust particles, comparable in size to soot and sand grains, are common. They create shooting stars when they collide with the earth's atmosphere. But very small dust particles are conspicuously absent. Astronomers believe that the very small dust particles have been blown out of the solar system by the sun. By comparing the forces on dust particles, determine the diameter of the smallest dust particles that can remain in the solar system over long periods of time. Assume that the dust particles are spherical, black, and have a density of 2000kg/m^3. The sun emits electromagnetic radiation with a power of 3.9×10^26W.An electromagnetic wave has wavelength λ and frequency f.
