Consider a point charge +q at a distance d above an infinite grounded conducting plane.
(a) Determine the charge density induced on the surface, then integrate to find the total surface charge.
(b) Find the force that the point charge exerts on the conductor by considering the force on the induced surface charge density.
Compare with the result of a force calculation on the image charge
Specifications of an analog filter are given below: Butterworth highpass filter Absolute passband gain=1 3-dB cutoff frequency at 4000 radians/second 40 dB attenuation at the stop frequency of 800 radians/second
The small identical conducting spheres have charges of2.0 x 10^-9C and - 0.5 x10^-9 Coulomb respectively. When they are placed 4 cm apart. what is the force between them If they are brought into contact and then separated by 4 cm
Sometimes the partial fraction expansion is not needed in finding the inverse Z-transform- instead the properties of the transform can be used. Consider the function F(z) = z+ 1/z^2(z - 1) a. Determine whether F(z) is a proper rational function as ..
You have a 10 nH inductor. What value of capacitor should you put in series with the inductor to achieve an impedance of Z=j50 ohm at f=1.0 GHz
a certain radio frequency generator delivers a power level of 12 dBm. If this signal is amplified, calculate how many decibels of gain is required to produce a power of 20 dBm.
The discharge tube of an Argon ion laser has windows 1 mm thick, with an index of 1.46, set at the Brewster angle to the axis of the tube. Specify this angle and the polarization of light that is not reflected by these windows.
In the digital communication link the data rate is 500 kb/s. The modulator generates the binary FSK signal. a) Determine the transmitted bandwidth if the difference between two frequencies fc1 - fc0 = 300 kHz
The voltage response for the circuit is known to be v(t)= D1te^-500t + D2e^-500t. The initial current in the inductor is -10mA and the initial voltage on the capacitor = 8V. The inductor has an inductance of 4H,
The voltage across a resistor is given by Ohm's Law: V=R I. Write a program that asks for resistance R in ohms, and current I in amps for several resistors, then calculates and displays the voltage across each resistor.
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
What are the main characteristics of the core : 1) of a step-index multimode optical fiber 2) of a graded-index multimode optical fiber 3) of a single mode optical fiber
1) 70 lbs/hr of steam at 300 psia, 500oF passes through a turbine which expands it to a pressure of 30 psia. If the turbine operates with an efficiency of 70%: a) What is the temperature of the steam leaving the turbine
