The Electromagnetic Spectrum
Please respond to the following:
Watch the video titled "What Are Gamma Rays?" (1 min 39 sec) under the Gamma Rays terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=PPlrtgilgK8. Next, give your opinion on whether or not the benefits of space exploration to the Moon and Mars outweigh the risks and costs of exposing such travelers to gamma rays above Earth's atmosphere. Provide a rationale for your response.
Watch the video titled "Video Tour of the Electromagnetic Spectrum" (5 min 3 sec) under the EM Spectrum terms section of the Science Corner. You can also view the video athttps://missionscience.nasa.gov/ems/emsVideo_01intro.html. Next, describe one to two ways that you encounter and utilize electromagnetic radiation in your daily life. Note: Feel free to include both naturally occurring examples, as well as any man-made technologies.
Choose a technology device that makes use of the EM Spectrum. Next, explain how this device works using terminology learned in this chapter.
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss
A touch sensor base on a piezoresistor built into a micromechanical cantilever made of silicon is cnnected in a Wheatstone-bridge configureation with a Vo = 1 volt. If L = 1.44cm and W = 1 cm
A penstock is used to bring water from behind a dam into a turbine. the effective head is 20 m and the flow rate of water is 50m^3/s. Compute the power of the water exiting the penstock.
An LTID system frequency response over |omega|
A large billet of steel initially at 260°C is placed in a radiant furnace where the surface temperature is held at 1200°C. Assuming the billet is infinite in extent, compute the temperature at point P shown in the accompanying sketch after 25 min ..
Determine the initial x(0+) and final value x(infinity), given the following Laplace transforms X(s): X(s) = 2s2 + 5/s3 + 3s + 1
given appositive number α, determine the constants A,B,C such that the iteration converges locally to 1/α with orderp= 3. (this will give a cubically convergent method for computing the reciprocal 1/α which uses on addition, subtraction, and multi..
Suppose a 1 meter long bar expands 0.5 centimeters when heated. By how much will a 100 meter long bar of the same material expand when similarly heated?
Consider the BJT differential amplifier when fed with a common-mode voltage VCM . As is often the case, the supply voltage VCC may not be pure dc but might include a ripple component vr of small amplitude and a frequency of 120 Hz.
In this homework, you are required to design reinforcement for bending and check shear (and design stirrups) for a typical beam in the East-West (E-W) direction in a floor system in an office building as shown in the figure.
design must mention the values of the resistors, capacitors, average and maximum current through the diodes, transformer turn ratio and the current carrying capacities of the transformer coils. Present these values neatly in a tabular form.
Ethylene is first chlorinated to form tetrachloroethane, which is dehydrochlorinated to form trichloroethylene. The standard heat of formation of liquid trichloroethylene is -276.2 kJ/mol. Use the given data and tabulated data for ethylene and HCl..
