What is the atomic polarizability of argon? Its susceptibility at 273K and 1atm is 4.35x10-4.Treat as an ideal gas ie it obeys pV=nRT law where pis pressure, V is volume, n is number of moles, R=82.056*10-6 m3-atm/mole-K is the universal gass constant and T is th absoulte temperature.
A 1(lambda) wavelength long line has parameter R=0.2 Ohm/m, G=0.002 mho/m, L=15 muH/m and C=2.31pF/m. The line is operated at a frequency f=2.5 GHz. It is terminated with a load impedance of 100 Ohms.
A charge density of ohm Coulombs per square meter is uniformly distributed over a thin and very long cylindrical shell of radius a. You want to know the electric flux density field D and the electric field E generated by this charge at all points ..
Unfortunately, nick is pretty lazy and doesn't want to design another filter. thinking twice the filtering gives twice the proforamce," he suggests filtering the audio signal not once or twice with a cascade of 2 idential filters.
A spectrum analyzer is used to verify an FM signal with a carrier frequency of 100.3 MHz, a modulation frequency of 15 kHz, and a modulation index of 2.4. a.) Predict the spectrum-analyzer display for the signal
For the circuit of Figure the following parameters are given with Vcc = 18 volts DC: Rs = 0 ohm r pi = 1000 ohm Rb = 1750 ohms C1 = 10 microfarads gm = 50mS RL = 100 ohms Ce = 0.1 microfarads Re = 135 ohms C2 may be considered very large
A three-phase, 2300-V, 60-Hz, cylindrical-rotor synchronous motor has a synchronous reactance of 10 ohms per phase and negligible armature resistance. The motor delivers 250 hp at a power angle of 20 electrical degrees, and the efficiency is 90%
The amplifier is connected to the handset antenna which has an impedance of 35 + j10 at one unspecified operating frequency. Find the inductive reactance and capacitive reactance needed to match the transmitter output to the antenna
A. Two machinery options are described below. Calcuate the present value of each of the items specified. Assume an interest rate of 6% and a useful life of 8 years. Show all the necesary work to calcualte value.
A 50 hp, 460 V, three phase induction motor draws 61 amps when operating at rated voltage and at a power factor of 0.85 lagging when supplying a rated load. knowns: 1hp=746watts effeciency (n) = Pout/Pin = Pout/(Pout+losses)
A series RLC circuit has a resonant frequency of 40 kHz and the Q is 20. At what frequency will the phase angle be 45 degrees
If PH7=0, the servo rotates at 50% of max speed; otherwise, full speed. Make your own choice of PWM channel and clock. Write brief comments. Compile your program in CodeWarrior IDE and make sure it is free of syntax errors.
Low doped silicon is used in partide detectors, in order to obtain a wide depletio region. Consider a pn junction with p-side doping Na = 5 X 1012 cm-3 and n side doping Nd = 1017 cm ".
