A cube is defined by 1 < x,y,z <1.2.If D=2x^2yax +3x^2y^2ay C/m^2.
a)apply gauss's law to find the total flux leaving the closed surface of the cube.
b)evaluate - *D at v the center of the cube.
c)estimate the total charge enclosed within the cube.
The silicon cube you were shown consisted of 4x4x4 unit cells. You were shown one dopant in the silicon cube. Given that the lattice constant of silicon is 0.543 nm. Calculate the dopant density represented by the 4x4x4 silicon cube simulation.
Can protons every flow through current? Even though in the overwhelming majority of cases the current flowing through a material is dominated by the movement of electrons"
A wave propagates 50m through a dielectric of region 1. Region 1 is lossy. Here, f= 0.6 Np/m. At an interface to region 2, the reflection coefficient is r =0.2+j0.5. The wave then propagates 50m back into region 1 from where it originated.
The s-plane diagram of a filter shows that it has a cluster of four poles in the left-half s-plane that are arranged in a semi-circle near +/- j628. The filter also has two zeroes at the origin.
The Y-Connected synchronous motor whos nameplate is shown in Figure 1 has a per-unit synchronous reactance of 0.9 and a per-unit resistance of 0.02. a.) What is the rated input power of this motor
When the starter motor, which draws 90A, is running the terminal voltage drops to 11V. What is the internal resistance of the battery What percentage of the chemical power is delivered to the starter motor
Determine(using the thevenin equivalent circuit) what size resistor should be placed betweent R4 and R5 to ensure that resistor receives the maximum power possible from the power source
Discuss why it is important to consider the Gain Bandwith Product (GBW) and the Slew Rate (SR) when selecting an op amp for a particular application. What other factors are important and why.
Write at least one paragraph explaining why the power factor of the motor changes as the rotor mechanical speed changesin the induction motor. evaluate when the machine is operating in motor mode or generator mode.
Convert function H(A, B, C) = (AB + C)(AC + B) into both the sum-of-products and product-of-sums forms. Obtain the truth table and express the function in both canonical forms: sum-of-minterms and product-of-Maxterms.
Let the input to a singly-balanced mixer, f(t), be given by V0 Sin (2 pi fs t). The local oscillator input p(t) is a square wave, alternating between 0 and +1 volt. The freqency of the square wave is 10 MHz, while for the input, fs is 100 KHz.
A transistor amplifier has a midband gain of -120, a high cutoff frequency of 36KHz, and a bandwidth of 35.8 KHz. In addition, the actual response is also about -15 dB at f=50Hz. Write the transfer function Av for the amplifier.
