Answer:
(a) air
Explanation:
in the following given quenching materials air is the least serve quenching action quenching is a process of heating the material and then rapidly cooling it. Quenching freezes the structure of the material including stresses. Oil has the most sever in its quenching action the commonly used used oil for quenching process is peanut and canola oil
Answer:
) You must create a Low Pass Filter for an audio amplifier. You must pass 10khz and block
60khz. In designing this, you must choose a cutoff frequency exactly half way between
these two frequencies. In addition, you must use a 0.2uF capacitor in you LPF circuit.
Given these criteria, analyze this circuit, and determine the necessary resistor value in
Ohms. Find the output Voltage at both ends of the spectrum. Based on your results, is
this a good design? NOTE: You MUST show your work (when using MS Word, choose
“Insert”--- “Equation”). (6 marks)
a. Solve for fc
b. Solve for R
c. Solve for Vout at 10khz
d. Solve for Vout at 60khz
e. Good design> (yes or no with an explanation)
Explanation:
Answer:
An opamp is an operation amplifier. It takes an input signal and amplifies it on the output side.
An ideal opamp should have infinite impedance at its input, infinite gain on the output, and zero impedance on the output
Answer:
When a pilot pushes the top of the right pedal, it activates the brakes on the right main wheel/wheels, and when the pilot pushes the top of the left rudder pedal, it activates the brake on the left main wheel/wheels. The brakes work in a rather simple way: they convert the kinetic energy of motion into heat energy.
Answer:
Diode equation for reverse saturation current
Voltage at which diode goes into Resistive region:V=-5 volts
Voltage at which high level injection occurs:Va=0.55 volt
Voltage at which avalanche multiplication occurs:V=5volts
Explanation:
we take here forward and reverse 0.7 volt and -5 volt
As Diode current equation is express as
....................1
here is total current through the diode and is reverse saturated current and is voltage drop across diode and is idealized factor and is thermal voltage
so here we know that when Bios is forward than
= .................2
ans Bios is Reverse than
= ..................3
so here
1. diode reverse saturation current is express as
and
2. Voltage at which diode go into Reverse behavior will be
= = -5 volt
and
3. voltage at which high level injection occur that is
Va = 0.55 volt
and
4. voltage at which avalanche multiplication occurs is
Va = 5 volt
