A resonator is constructed from a 3.0 cm length of 100 air-filled coaxial line, shorted at one end and terminated with a capacitor at the other end, as shown below.
(a) Determine the capacitor value to achieve the lowest order resonance at 6.0 GHz.
(b) Now assume that loss is introduced by placing a 10,000 resistor in parallel with the capacitor. Calculate the unloaded Q.
A 100-MVA 11.5-kV 0.8-PF-lagging 50-Hz two-pole Y-connected synchronous generator has a per-unit synchronous reactance of 0.8 and a per-unit armature resistance of 0.012. What are its synchronous reactance and armature resistance in ohms?
At a certain location, the horizontal component of the earth's magnetic field is 3.70 10-5 T, due north. A proton moves eastward with just the right speed for the magnetic force on it to balance its weight. Find the speed of the proton.

Write an MIPS assembly language program to calculate (2* ! N ) where ! is the factorial of a given positive integer N using loop.
Analyze the synchrounous circuit with input X and output Z constructed with two flip flop of JK type with outputs QA and QB. The flip flop input exciatation are as follows: JA=XQB; KA=0; Jb=XQA'; KB=QA. the output equation is Z=XQB'.
The current is due to free electrons moving through the wire at an average velocity of v meters/second. If the concentration of free electrons is 10^29 electrons per cubic meter and if they are uniformly dispersed throughout the wire, then what is..
The frame object from question 1 uses a BorderLayout by default. Write Java statements to create a JTextfield object and place it into the bottom part of the frame object's window. Describe the sequence of steps needed to create 3 labels and place
Explain how energy efficiency can be traded off for bandwidth efficiency by multilevel modulation schemes. Rank the following modulation schemes: 64-ary PSK, Binary FSK, QPSK in terms of bandwidth efficiency and energy efficiency.
The rate at which thi filter "rolls off" at low frequencies is said to be 20 dB/ decade. Can you brief explain the meaning of this statement in terms of the way the output voltage varies with frequency at frequencies below fc
A three phase, 25-hp, 440-V, 60-Hz, 1750 rpm, wound-rotor induction motor has the following equivalent circuit parameters:R1=0.20 ohms, X1=1.0 ohms, R2=0.15 ohms, X2=0.8 ohms, Xm=30 ohms The motor is connected to a three phase, 440-V, 60-Hz supply.
Find the ABCD constants of a π circuit having a 600-Ω resistor for the shunt branch at the sending end, a 1-kΩ resistor for the shunt branch at the receiving end, and an 80-Ω. resistor for the series branch.
