To achieve an impedance at resonance that is one-fifth the impedance at 10 kHz, a value of R can be calculated using the relationship between impedance and resistance in an electrical circuit.
In an electrical circuit, the impedance is a complex quantity that includes both resistance (R) and reactance (X). At resonance, the reactance cancels out, leaving only the resistance component. To find the value of R that results in an impedance at resonance that is one-fifth the impedance at 10 kHz, we can set up a relationship between the two impedances.
Let's denote the impedance at resonance as Z_res and the impedance at 10 kHz as Z_10kHz. According to the desired condition, Z_res = (1/5) * Z_10kHz.
Impedance is given by the formula Z = √(R^2 + X^2), where X is the reactance. Since we want only the resistance component, we can rewrite the equation as Z = R.
Substituting the values, we have R_res = (1/5) * R_10kHz. This means that the value of R at resonance should be one-fifth of the value of R at 10 kHz.
By calculating the resistance value at 10 kHz and dividing it by 5, we can determine the specific value of R that should be used to obtain the desired impedance ratio.

a student set up the circuit shown for her electronics class. assuming e m f = 8.70 v and r = 5.00 ω, find the following quantities.
We found that the current flowing through the circuit is 1.74 amperes, the voltage drop across the resistor is 8.70 volts, and the power dissipated by the resistor is 15.14 watts.
To start, we have the circuit shown with an EMF (electromotive force) of 8.70 volts and a resistance (R) of 5.00 ohms. We need to find the following quantities: Current (I) flowing through the circuit Voltage (V) drop across the resisto Power (P) dissipated by the resistor.
To find the current (I), we can use Ohm's Law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. So, we have: I = V/R where V is the voltage (EMF) and R is the resistance. Plugging in the values we have, we get:
I = 8.70/5.00 = 1.74 amperes.

Let's consider the case when we increase the number of elements to 5. How many temperature values will we need to obtain to determine the variation of temperature along the line?
We have a total of 6 nodes with 5 components. We must determine the temperature at each of these six nodes. Mesh refining is the process of increasing the number of elements.
What is temperature?
Temperature is a scientific term that describes how hot or cold something is.There are three types of temperature scales: those described in terms of the average translational kinetic energy per freely moving microscopic particle in a body, such as an atom, molecule, or electron, such as the SI scale; those which rely solely on purely macroscopic properties as well as thermodynamic principles, including such Kelvin's original definition; and those that are not defined by theoretical principles, and yet are defined by convenient empirical properties of particulate matter.

Consider the following Moore’s law growth pattern (since 1980) for the number of transistors inside a particular commercial microprocessor: N = 1920 x 10 0.1637(Y – 1980) where Y is the year and N is the number of transistors. Assuming sustained Moore’s law growth, what will be the number of transistors in a microprocessor in year 2025? Using the same expression, calculate how many years it will take for the transistor count to increase by 100x
Answer:
No. of transistors = \($4.1524 \times 10^{10}$\) transistors
Explanation:
Given that:
N = \($1920 \times 10^{0.163(Y-1980)}$\)
Y = 2025
N = \($1920 \times 10^{0.163(2025-1980)}$\)
N = \($4.1524 \times 10^{10}$\) transistors
Now at Y = 1980
Number of transistors N = 1920
Therefore,
\($1000 = 10^{0.163(Y-1980)}$\)
\($\log_{10} 1000=0.163(Y-1980)$\)
\($\frac{3}{0.163}=Y-1980$\)
18 ≅ 18.4 = Y - 1980
Y = 1980 + 18
= 1998
So, to increase multiples of 1000 transistors. it takes 18 years.
non-volatile memory is temporary and loses its contents when the power is turned off. T/F
Answer:
False
Explanation:
Non-volatile memory is a category of memory that retains its data even when the system is turned off or the power is off. It is sometimes referred to as static or permanent memory. For example, hard disk. Therefore, the given statement is false.
Answer:
TRUE
Explanation:
Volatile memory is memory or storage that loses its data when the computer's power is switched off. Volatile memory is a nonpermanent memory because when the power is off it loses its contents.

An unknown relative passes away and bequeaths upon you a small tract of land in Amherst. You decide to build a two-story storage facility to make the best of your bequest. But your self-storage dream is in jeopardy due to a 10 meter thick layer of soft clay (N<4) on the site. You put on your best geotechnical engineer hat, hire a driller to pull up some samples, and send them off to a lab for a consolidation test. The report indicates that the clay is a dark grey, slightly sweet, kaolinite blend with a cy = 1x10-7 mº/s, single-drained, and an ultimate settlement of 0.73 meters. It does not make financial sense to install deep foundations, so you are interested in how long it will take to consolidate the clay layer using a passive load.
How long will it take for settlements of 25, 50, and 65 cm to occur?
If you need to build within the next 12 months and have at least 65cm of settlement to be viable, does it make sense to proceed?

Explanation:
An automobile having a mass of 1100 kg initially moves along a level highway at 120 km/h relative to the highway. It then climbs a hill whose crest is 80 m above the level highway and parks at a rest area located there. Use a reference with kinetic and potential energy each equal to zero for the stationary highway before the hill. Let g = 9.81 m/s^2.
For the automobile, determine its change in kinetic energy and its change in potential energy, both in kJ. For the automobile, determine its change in kinetic energy, in kJ.
a. -8594
b. -663.1
c. -6.63x10^5
d. 663.1
Answer:
\(-6111.11\ \text{kJ}\)
\(863.28\ \text{kJ}\)
Explanation:
m = Mass of automobile = 1100 kg
v = Velocity of car = 120 km/h = \(\dfrac{120}{3.6}\ \text{m/s}\)
h = Height of hill = 80 m
g = Acceleration due to gravity = \(9.81\ \text{m/s}^2\)
Change in kinetic energy
\(KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}\)
Change in kinetic energy is \(-6111.11\ \text{kJ}\)
Change in potential energy is given by
\(PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}\)
The change in potential energy is \(863.28\ \text{kJ}\).
A well-insulated heat exchanger has one line with 2 kg/s of air at 125 kPa and 1000 K entering, and leaving at 100 kPa and 400 K. The other line has 0.5 kg/s water entering at 200 kPa and 20 °C, and leaving at 200 kPa. Calculate the exit temperature of the water and the total rate of entropy generation?
Answer:
120°CExplanation:
Step one:
given data
T_{wi} = 20^{\circ}C
T_{Ai}=1000K
T_{Ae}= 400kPa
P_{Wi}=200kPa
P_{Ai}=125kPa
P_{We}=200kPa
P_{Ae}=100kPa
m_A=2kg/s
m_W=0.5kg/s
We know that the energy equation is
\(m_Ah_{Ai}+m_Wh_W=m_Ah_{Ae}+m_Wh_{We}\)
making \(h_{We}\) the subject of formula we have
\(h_{We}=h_{Wi}+\frac{m_A}{mW}(h_A-h_{Ae})\)
from the saturated water table B.1.1 , corresponding to \(T_{wi}= 20c\)
\(h_{Wi}=83.94kJ/kg\)
from the ideal gas properties of air table B.7.1 , corresponding to T=1000K
the enthalpy is:
\(h_{Ai}=1046.22kJ/kg\)
from the ideal gas properties of air table B.7.1 corresponding to T=400K
\(h_{Ae}=401.30kJ/kg\)
Step two:
substituting into the equation we have
\(h_{We}=h_{Wi}+\frac{m_A}{mW}(h_A-h_{Ae})\)
\(h_{We}=83.94+\frac{2}{0.5}(2046.22-401.30)\\\\h_{We}=2663.62kJ/kg\)
from saturated water table B.1.2 at \(P_{We}=200kPa\) we can obtain the specific enthalpy:
\(h_g=2706.63kJ/kg\)
we can see that \(h_g>h_{Wi}\), hence there are two phases
from saturated water table B.1.2 at \(P_{We}=200kPa\)
\(T_{We}=120 ^{\circ} C\)
