how to make demultiplexer using or gates?
Answer:
A demultiplexer (DEMUX) is a digital circuit that routes a single input line to one of several output lines. It can be implemented using OR gates.
Here's one way to make a 2-to-4 demultiplexer using OR gates:
Begin by connecting the input line to the input of the first OR gate.
Connect one of the select lines to the second input of the first OR gate.
Connect the output of the first OR gate to one of the outputs.
Connect the second select line to the second input of the second OR gate.
Connect the output of the first OR gate to one input of the second OR gate.
Connect the output of the second OR gate to the second output.
Repeat steps 4-6 for the remaining outputs.
By this way you can construct a demultiplexer using OR gates.
It's important to note that the number of select lines must be equal to the number of bits required to select the output. In this example, we used 2 select lines to control the 4 outputs, so we only needed 2 bits to select the output.

What is the upper cut-off frequency?
The low pass and high pass filters make up the bandpass filter. High pass filters have a higher cutoff frequency, which is the initial cutoff frequency they use. Known as FC high, this cut-off frequency.
Explain about the cut-off frequency?A signal's cutoff point is determined by the cutoff frequency. There are only lowpass filters on simpler synthesisers. If a signal comprises frequencies between 20 and 4000 Hz and the cutoff frequency is set at 2500 Hz, frequencies above that frequency are filtered out.
For a high pass RL filter, follow these steps to determine the cutoff frequency: Inductance value (L) multiplied by two. Subtract the value from step 1 from the resistance (R). You've established what the high pass RL filter's cutoff frequency is.

Learn how changes in binding free energy affect binding and the ratio of unbound and bound molecules. Similar to the lecture, our example is a drug molecule D and a drug target enzyme E. The drug target enzyme E is commonly found in concentrations [E]tot of 250 nM, i.e. 2.5 x 10-7 mol/l. The drug D binds to E to form the complex ED with a dissociation constant of KD = 1.30 µM (i.e. 1.30 x 10-6). The dissociation constant has been determined at room temperature, i.e. for T = 298.15 K.
In order to estimate the effectivity of the drug D, calculate the ratio of the concentration of the free, unbound drug molecules [D] and the bound complex [ED], i.e. [D]/[ED], for the conditions described in part B. Provide your answer with 3 significant figures.
The margin of error is 2%.
The binding free energy for the formation of the complex ED is -2.94 kJ/mol.
The binding free energy for the formation of the complex ED can be calculated using the equation ΔG = -RTlnKD. Using the given values of R (8.314 J/mol·K), T (298.15 K), and KD (1.30 x 10-6), we get:
ΔG = -(8.314 J/mol·K)(298.15 K)ln(1.30 x 10-6) = -2.94 kJ/mol
2.) To find the dissociation constant for the complex ED', we use the equation ΔG = -RTlnKD. The binding free energy for ED' is 10.5 kJ/mol more negative than for ED, so we can substitute in the new value for ΔG:
ΔG' = -2.94 kJ/mol - 10.5 kJ/mol = -13.44 kJ/mol
Solving for KD':
KD' = e^(-ΔG'/RT) = e^(-(-13.44 kJ/mol)/(8.314 J/mol·K)(298.15 K)) = 2.09 x 10^-7 mol/l
3.) To find the total concentration of the drug D' that is needed to bind 50% of the enzyme E, we use the equation:

Figure 0.1 shows the circuit diagram of a magnetic stimulator made by an internationalbiomedical electronics company. The pulsed magnetic field generated by the transducer coil(represented by the inductor) can be used in a variety of medical treatments including nervestimulation. The capacitor is precharged to a Voltage Vx between 0 and 1000 V, and then at t = 0the switch S is closed to trigger the magnetic pulse.Calculate the following assuming that the switch S and the diode D are ideal:1. The time response of the coil current after the switch S is closed, as a function of theprecharge voltage Vx. (Some types of stimulation require a field with a fast rise time anda slow fall time.)2. The peak coil current for Vx = 950 V.3. The time t1 at which diode D turns on.4. The energy dissipated in the resistor for Vx = 950 V
The theory used in this question is based on the analysis of RC circuits. Energy dissipated in the resistor for Vx = 950 V
E = 950^2/(2*R*C).
Analysis of RC circuits
This type of analysis is used to determine the time response of a circuit, as well as the current and energy dissipated in different components. Specifically, this question uses the equation for the current in an RC circuit (I = CdV/dt) and the equation for the power dissipated in a resistor (P = I^2 * R) to calculate the time response, peak current, and energy dissipated in the resistor for a given precharge voltage.
1. The time response of the coil current after the switch S is closed, as a function of the precharge voltage Vx, can be determined by analyzing the RC circuit.
The current in the coil is given by: I = CdV/dt, where C is the capacitance and V is the voltage across the capacitor.
At t = 0, the capacitor is precharged to Vx, and the current will rise exponentially until the diode turns on, at which point the current will plateau.
Therefore, the time response of the coil current is given by:
I(t) = I0 * e^(-t/RC),
where I0 is the initial current determined by Vx, R is the resistance of the resistor, and C is the capacitance of the capacitor.
2. The peak coil current for Vx = 950 V can be determined using the equation above.
Since the capacitor is precharged to 950 V, the initial current is given by:
I0 = 950/(R*C).
Substituting this value into the equation for I(t) and solving for t = 0 gives the peak coil current:
Ipeak = 950/(R*C).
3. The time t1 at which diode D turns on can be determined by examining the equation for I(t).
The diode will turn on when the current reaches the peak value, which occurs when t = 0.
Therefore, t1 = 0.
4. The energy dissipated in the resistor for Vx = 950 V can be determined by integrating the power dissipated in the resistor over time. The power dissipated in the resistor is given by:
P = I^2 * R.
Therefore, the energy dissipated in the resistor is given by:
E = integral from 0 to infinity of I^2 * R dt.
Substituting the equation for I(t) into this equation and solving for t = 0 gives the energy dissipated in the resistor for Vx = 950 V:
E = 950^2/(2*R*C).

1. A steel container expands in volume 1% when the pressure with in it is increased by 70Mpa. At standard pressure, it holds 8kg of water; =1000kg/m3. For K=2.05Gpa, when it is filled, how many kilograms of water must be added to increase the pressure to 70Mpa (gage)?
Using the ideal gas law to solve the question,
We need to add 0.331 kg of water to increase the pressure to 70 MPa.
How The ideal gas law was appliedWe can use the Ideal Gas Law to solve this problem.
The Ideal Gas Law states that PV = nRT,
where P is the pressure,
V is the volume,
n is the number of moles,
R is the gas constant,
T is the temperature (assumed to be constant).
We know that the container expands by 1% when the pressure is increased by 70 Mpa, so the change in volume is (1/100)V.
We can use this to find the initial volume of the container:
V = (1/0.01) * (1/100)V = 100V
We also know that at standard pressure, the container holds 8 kg of water, which we can assume is 8 liters. So the volume of the container at standard pressure is 8 L.
We can use the bulk modulus of elasticity of steel, K = 2.05 Gpa, to find the change in pressure.
K = (Delta P) / (Delta V/V)
Delta P = K * (Delta V/V)
Delta P = (2.05 * 10^9 Pa) * (1/100) = 2.05 * 10^7 Pa
This is the same as 20.5 MPa. So we need to add 49.5 MPa (70 - 20.5 = 49.5) more pressure to fill the container to 70 MPa.
Now we can use the Ideal Gas Law to find the number of moles of water we need to add to increase the pressure by 49.5 MPa.
PV = nRT
n = (PV) / (RT)
n = (49.5 * 10^6 Pa * 8 L) / (8.314 J/mol·K * 300 K)
n = 0.0186 moles
To find the mass of water we need to add, we can use the molar mass of water, which is 18.02 g/mol:
mass = n * molar mass
mass = 0.0186 moles * 18.02 g/mol
mass = 0.331 kg
So we need to add 0.331 kg of water to increase the pressure to 70 MPa.

Determine the magnitude and orientation, measured counterclockwise from the positive y axis, of the resultant force acting on the bracket, if FB= 600 N and θ = 20°
If FB = 600 N and = 20°, calculate the magnitude and direction of the resulting force acting on the bracket, measured counterclockwise from the positive y axis. 214) 105°.
How can the strength and direction of the resulting force be determined?
If FB = 600 N and = 20°, calculate the size and direction of the resultant force acting on the bracket, measured counterclockwise from the positive y axis. 214) 105°. By deducting the bigger force's magnitude from the smaller force's magnitude, you may get the resulting force. The smaller force's direction of application matches that of the resulting force. Due to the fact that force is a vector quantity, it possesses both magnitude and direction.
A force's strength is quantified by a number called its magnitude. Take a force of 10 N, for instance, in the direction of the east. The phrase "towards east" denotes a direction, and "10" represents the force's magnitude.

define a class named history with the following public interface: class history { public: history(int nrows, int ncols); bool record(int r, int c); void display() const; }; the constructor initializes a history object that corresponds to an arena with nrows rows and ncols columns. you may assume (i.e., you do not have to check) that it will be called with a first argument that does not exceed maxrows and a second that does not exceed maxcols, and that neither argument will be less than 1. the record function is to be called to notify the history object that a poisoned carrot has been dropped at a grid point that does not currently have a poisoned carrot. the function returns false if row r, column c is not within the bounds implied by the history constructor; otherwise, it returns true after recording what it needs to. this function expects its parameters to be expressed in the same coordinate system as an arena (e.g., row 1, column 1 is the upper-left-most position). the display function clears the screen and displays the history grid as the posted programs do. this function does clear the screen, display the history grid, and write an empty line after the history grid; it does not print the press enter to continue. after the display (that should be done somewhere else in the program). (note to xcode users: it is acceptable that clearscreen() just writes a newline instead of clearing the screen if you launch your program from within xcode, since the xcode output window doesn't have the capability of being cleared.)

What is meant by public interface?The logical point where different software entities communicate is known as a public interface in computer science. A single computer, a network, or a variety of other topologies may be used for the entities to interact with one another.A class's public properties and methods (variables or fields you may read the values of or assign to) form its public interface (functions you can call). Therefore, the task is to develop something that is not a subclass of LinkedList.For instance, protected methods could be accessed by creating a subclass.Due to the fact that an interface is a contract meant to be utilized by other classes, interface methods are implicitly public in C#.

an 8 kip axial load is applied t a short wooden post that is supported by a concrete footing resting on undisturbed soil. determine (a) the maximum bearing stress on the concrete footing (b) the size of the footing for which the average bearing stress on the soil is 21 psi
3.33 MPa is the maximum bearing stress on the concrete footing. A footing that is 525 mm x 525 mm in dimension will have an average bearing stress of 145 kPa.
Find the maximum bearing stress?A) 3.33 MPa is the maximum bearing stress on the concrete footing.
B) A footing that is 525 mm x 525 mm in dimension will have an average bearing stress of 145 kPa.
A) The footing image is missing, therefore I have attached it.
The short wooden post's measurements, according to the provided image, are;
120 mm wide equals 0.12 meters.
length is 100 mm, or 0.1 m.
the wooden post's vicinity is;
A = 0.12 × 0.1
A = 0.012 m²
Maximum bearing stress is calculated as follows:
σ max = F/A
We receive; F = 40 kN = 40 000 N is the force.
Thus;
σ max = 40000/0.012
σ max = 3.33 × 10⁶ Pa
3.33 MPa for _max
B) The average bearing stress is reportedly 145 kPa (145000 Pa) at this time.
In light of the fact that A = b2, = F/A 145000 = 40000/A (since the footing is square)
The result is that b2 = 40000/145000 b2 = 0.2758620689655 b = 0.2758620689655 b = 0.525 m b = 525 mm.
