1. In a certain crystalline material the vacancy concentration at 25*C is one-fourth that at 80*C. At what temperature would the vacancy concentration be 3 times that at 80*C?
2. Suppose one attempts to add a small amount of Ni to Cu in an effort to create a solid solution.
a.) Which element is the solvent and which is the solute?
b.) Do you think the resulting solid solution (S.S.) will be a substitutional S.S. or an interstitial S.S. Why?
c.) Do you think Ni and Cu will be completely soluble in each other? Why or why not?
3. What type of solid solution is likely to be formed when C is added to Fe?
what is the shortest possible line length that would exhibit the desired reactance at its input?
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
Shuffle a deck of cards and pick two cards at random. Observe the sequence of the two cards in the order in which they were chosen. (a) How many outcomes are in the sample space (b) How many outcomes are in the event that the two cards are the same ..
A manufacturer specification sheet lists the transfer function of a pressure sensor as 45±5% mV/kPa with a time constant of 4±10%. A highly accurate test system applies a step change of pressure from 20 kPa to 100 kPa.
Three single phase 2400v/240v transformers are connected for operation as a 4160/240 v 3phase bank. Each transfomers has a Zeq1=1.42+j1.82 ohms and rated at 150kva
Implementation of the project with the analog and digital modulation techniques
In a binary digital communications systems, the bit energy required at the receiver input terminals is 50x10^-18 JOther parameters are as follows: Gt(dB)=24 dB Gr(dB)= 26 dB f= 10GHZ d=40,000 km
An electrical energy source forces a constant current of 500(mA) through a light bulb for one hour. If 12.6(kJ) is given off in the form of light and heat energy, calculate the voltage drop across the bulb.Use Engineering Notation with 3 decimal p..
A digital system has a clock generator that produces pulses at a frequency of 16 MHz. Design a circuit (draw the logic diagram) that provides a clock with a cycle time of 250 ns.
A sinusoidal current is zero at t = - 625 s and increasing at a rate of 8000 A/s. The maximum amplitude of the current is 20 A. a) What is the frequency of i in radians per second
If V = 12sin( 2 pi 1800 + 45). What would you read on a DMM Would this voltage be for an inductor or capacitor What would be the frequency and phase What does the 12 stand for Explain.
