what is the modulus of a 6 stage johnson counter
Answers
A Johnson counter is a type of shift register that is composed of flip-flops and is used to generate a sequence of binary codes. It is also known as a "twisted ring counter" or "walking ring counter" because the sequence of binary codes that it generates appears to be moving in a circular pattern.
A Johnson counter can have any number of stages, but in this case, we are specifically looking at a 6-stage Johnson counter.The modulus of a Johnson counter is the number of unique states that the counter can produce before it repeats itself. The modulus is calculated as 2^n, where n is the number of stages in the counter. In this case, the modulus of a 6-stage Johnson counter is 2^6, which equals 64.This means that a 6-stage Johnson counter can produce 64 unique binary codes before it repeats itself and starts generating the same sequence of codes again. The binary codes that it generates are determined by the state of the flip-flops in the counter and the connections between them. The sequence of codes that it produces is designed to be non-repeating and to cover all possible combinations of bits in a 6-bit binary number.In summary, the modulus of a 6-stage Johnson counter is 64, which means that it can produce 64 unique binary codes before it starts repeating itself. The Johnson counter is a useful tool for generating non-repeating sequences of binary codes and is commonly used in applications such as frequency dividers, digital counters, and sequence generators.

a. 3.4
b. 14.3
c. 25.9
d. 67.7
Answers
Answer:
Weight Percentage of Ash = 3.4
Explanation:
Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.
To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?
Solution -
Given that,
Coal Burned Rate = 10,000 kg/hr
= \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)
= 166.6666 kg/min
⇒Coal Burned Rate = 166.6666 kg/min
Now,
Given that,
Ash content in coal = 21 %
⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min
= 34.9999 ≈ 35 kg/min
⇒Ash in (coal that burned) = 35 kg/min
Now,
We know,
Density of water = 1000 kg/m³
Now,
Water flow Rate = \(1\frac{m^{3} }{min} * density\)
= 1000 kg/min
⇒Water flow Rate = 1000 kg/min
Now,
Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min
= 1035 kg/min
⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min
So,
Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100
= (35 ÷ 1035) × 100
= 3.38 ≈ 3.4
∴ we get
Weight Percentage of Ash = 3.4

based on elasticity theory, the stress is predicted to be infinite at a re-entrant corner of a plane stress model. to avoid false answers using the finite element method based on linear elastic material model assumptions, what must be done to the model?
Answers
"Use a theory that accounts for material yielding" to avoid false answers that use the method of finite elements based on linear elastic material model assumptions.
What is termed as the elasticity theory for stress?The ability of solid materials to deform when subjected to an external force and then return to their initial shape after forces have been removed is referred to as elasticity. The external force acting on a specific area is referred to as stress, and the degree of deformation is referred to as strain.Linear elasticity's fundamental "linearizing" assumptions are: infinitesimal strains or "limited" deformations (or strains), and linear relationships between stress and strain components. Furthermore, linear elasticity is only valid for stress states that don't result in yielding.Thus, "Use a theory that accounts for material yielding" to avoid false answers that use the method of finite elements based on linear elastic material model assumptions.

A customer got debited twice, how would you investigate and resolve this conflict on the customer side and on the company side?
Answers
Answer:
First, the question seems to assume that the debit is erroneous. Because, if it's intentional, then there is little need for an investigation.
So if there was an unintentional duplication of transaction, this would totally depend on what kind of debit it is. So to answer the question, we'll explore as many scenarios as possible.
Debit on a Bank Account (Business to Bank)
If it is a debit on the bank account, then the statement of account from the company side and the account activity(ies) leading up to the debits will reveal why there is a double debit. It is possible the transaction was entered twice. This can happen when there is a bad connection that creates a failed transaction message on the customer's end but still carries through with the payment instruction. In this case, the customer will think the debit or payment request didn't go through and proceed to repeat the same transaction.
Banks do execute debits on accounts for charges such as Bank Account Maintenance Charges, Credit card charges etc. Errors could also arise internally that led to the duplication of a debit instruction either due to a bug in the system.
So in this case, we'll need to access the customer's account internally whilst externally, the client will need to provide the message containing the alerts, date and time of debits etc. to help the banks further the investigation.
Business to Business
This could arise out of a "failed POS" transaction. Similar to the condition stated above, when there is a glitch with the network and the POS fails, it should print out a receipt that reads failed or declined.
This receipt will contain references to the transaction. This will aid the investigation of the debits to the account.

If the latitude and longitude of a point in Puerto Rico are 17º59'39" and 65º27'56.7", respectively, what is the angle of convergence γ for this point?(answer in decimals)
Answers
The angle of convergence γ for the given point in Puerto Rico is approximately 114.53425 degrees.
To find the angle of convergence γ, we need to convert the latitude and longitude from degrees, minutes, and seconds to decimal degrees.
Latitude: 17º59'39"
To convert minutes and seconds to decimal degrees, we divide the minutes by 60 and the seconds by 3600.
17º + (59/60) + (39/3600) = 17.9941667º
Longitude: 65º27'56.7"
Following the same conversion process:
65º + (27/60) + (56.7/3600) = 65.46575º
Now, we can use the formula for calculating the angle of convergence γ:
γ = 180º - |longitude|
Substituting the longitude value:
γ = 180º - |65.46575º| = 180º - 65.46575º = 114.53425º
Therefore, the angle of convergence γ for the given point in Puerto Rico is approximately 114.53425 degrees.

The bolt cutter is exerting a force of -600 N on the bolt. The negative sign indicates that the direction of this force is opposite to that of the forces applied to the handles.
To determine the magnitude of the forces exerted by the bolt cutter on the bolt, we need to use the principle of static equilibrium. This principle states that the sum of the forces acting on an object must be zero in order for the object to be in static equilibrium.
In this case, the forces acting on the bolt are the two 300 N forces applied to the handles of the bolt cutter, and the force exerted by the bolt cutter on the bolt. Let's call this force F. We can represent this situation with the following equation:

the two wires are connected together at a. if the force p causes point a to be displaced horizontally 2 mm, determine the normal strain developed in each wire.
Answers
The normal strain developed in each wire, Strain = ΔL / L = 4 mm / L. The factor of (2 mm / L) in the denominator is due to the horizontal displacement of point A being proportional to the length of the wire.
What is Normal Strain?
The normal strain in a wire can be calculated with given formula:
Strain = ΔL / L.
where ΔL is the change in wire-length and L is the original wire-length.
In this case, since the two wires are connected together at point A, they will experience the same amount of strain.
To find the strain in each wire, we first need to find the change in length of each wire due to the horizontal displacement of point A.
Let's assume that the length of each wire is L.
When point A is displaced horizontally by 2 mm, the change in length of each wire can be calculated as:
ΔL = 2 * (L / 2) * (2 mm / L) = 4 mm
Strain = ΔL / L = 4 mm / L.

R = x1+x2 = 0.76 +0.179 = 0.939 K/W
Now to calculate the temperature at the interface of the wire,
q= R(T - t)
=> 80 = 0.939(T -30- 273)
T = 378.12 K
Critical radius is r(critical)
r(critical) = K/h = 0.15/12 = 0.0125 m or 12.5 mm
Explain why the phase angle between the generator voltage and the resistor voltage decreases as the frequency is increased?
Answers
At low frequencies, the resistor behaves as a purely resistive element, meaning that the current flowing through it is in phase with the voltage across it. Therefore, the phase angle between the generator voltage and the resistor voltage is 0 degrees.
However, as the frequency of the AC signal increases, the impedance of the resistor becomes more complex, with both resistive and reactive components. The reactive component of the resistor's impedance is proportional to the frequency of the signal, so as the frequency increases, the reactive component becomes more significant.
This reactive component causes the current to lead or lag the voltage, depending on the sign of the reactance. In the case of a purely resistive element, the current leads the voltage by 90 degrees. As the frequency increases, the current leads the voltage by a smaller angle because the reactive component of the resistor's impedance becomes less significant at higher frequencies.
Therefore, the phase angle between the generator voltage and the resistor voltage decreases as the frequency is increased, approaching 0 degrees as the frequency becomes very high.
Answer:
The phase angle between the generator voltage and the resistor voltage in an AC circuit is determined by the relationship between the voltage and the current, as described by Ohm's Law.

Please mark me Brainliest
The drainage piping between the building foundation and the sewer main or septic tank is known as the sewer lateral or building sewer.
The drainage piping between the building foundation and the sewer main or septic tank is commonly referred to as the "sewer lateral" or "building sewer." This piping system is responsible for carrying wastewater and sewage from individual buildings or structures to the main sewer line or septic tank.
The sewer lateral is typically a buried pipe that connects the building's plumbing system to the larger sewer infrastructure. It is designed to transport wastewater, including water from sinks, toilets, showers, and other sources, away from the building and into the public sewer system or on-site septic system for further treatment or disposal.
In urban areas with centralized sewage systems, the sewer lateral connects the building's plumbing to the municipal sewer main. The sewer main is the primary pipe that carries wastewater from multiple buildings and eventually leads to a wastewater treatment plant.
