A glass tube with a cross-sectional area of 9^-2 m^2 contains an ionizd gas. The densities are 10^15 positive ions/m^ and 10^11 free electrons/m^3. Under the influence of an applied voltage, the postive ions are moving with an average axial velocity of 5 x 10^3 m/s. At that same point the axial velocity of the electrons is 1000 times as great. Calculate the electric current moving through.
a) Construct a choice table for interest rates from 0% to 100%. b) Which roof should you choose if your MARR is 12% what is the actual value of the IRR on the incremental cost?
The forward-bias current in a GaAs pn-junction at T = 300 K is ID = 15 mA. The reverse-saturation current is IS = 10^-19 A. Determine the required forward-bias diode voltage.
Write a report on Future Generation Telecommunication Technology.
The contects of a six-bit register are initially 100101. The register is shifted four times to the right, with the serial input being 1101. What are the contents of the register after each shift
A mixture consisting of 0.100 mole N2, 0.050 mol O2, 0.200 mole CH4, and an unknown amount of CO2 occupied a volume of 11.1 L at 27°C and 1.00 atmpressure. How many moles of CO2 are there in this sample
Construct a Phasor Diagram to represent the source voltage, source current, voltage drops, VR, and VL across the resistor and the inductor. The diagram does not need to be drawn to scale. However, the values of the items represented must be includ..
A process worker received an electric shock when she attempted to turn off a conveyer control. The toggle switch controlled the power to a variable speed drive. An examination found that dust had accumulated on the toggle switch. Moisture on the ..
Calculate the de Broglie wavelength, for: (a) An electron with kinetic energy of (a) 1.0 eV, and (ii) 100 eV. (b) A proton with kinetic energy of 1.0 eV. (c) A singly ionized tungsten atom with k in.
Three point charges are positioned in the x-y plane as follows: 5 nC at y = 5 cm, -10 nC at y = -5 cm, and 15 nC at x = -5 cm. Find the required x-y coordinates of a 20-nC fourth charge that will produce a zero electric field at the origin.
Compute the inverse Fourier transform for X(ω) = cos 4ω. 5. A signal with the highest frequency component at 10 kHz is to be sampled. To reconstruct the signal, the sampling must be done at a minimum frequency of?
Determine the periods and find exponential fourier series coeffecients of functions. A.) f(t) = 2(cost)(cos2t) B.) g(t) = 3 + 2e^-j2t + 2e^j2t + 2cos4t C.) h(t) = 4
1) For a forwarard converter, derive the minimum value of Vr - as a function of the input voltage Vg, the duty cycle D, and the turns ratio N1/N2 - that will cause the transformer magnetizing current to be reset to zero by the end of the switching..
