Answers

Answer 1
IDIV can accept 1, 2, or 3 operands. This means that the IDIV instruction can perform division with one, two, or three input values depending on the scenario.Specifying the data size of a variable in NASM is only necessary when the variable is a source operand. This means that if the variable is used as input for an operation, you need to specify its data size to avoid ambiguity.A value stored in the ebx register can be sign extended into edx:ebx with the CDQ instruction. This means that the CDQ instruction is used to extend the sign bit of the ebx register into the edx register, effectively combining both registers to form a larger, sign-extended value.The ALIGNB directive can only be used in the .bss section of NASM code. This means that if you want to align a variable or address in the .bss section, you would use the ALIGNB directive to achieve this.When using an extension instruction in GAS, you must append two characters to indicate the sizes of the source and destination operands. This means that you should specify the size of both the input and output variables for the extension instruction to ensure proper operation.

It is desired to obtain 500 VAR reactive power from 230 Vrms 50 Hz 1.5 KVAR reactor. What should be the angle of the AC to AC converter to be used? Calculate the THD of the current drawn from the mains (consider up to the 12th harmonic)?

Answers

Answer:

14.5° ; THD % = 3.873 × 100 = 387.3%.

Explanation:

Okay, in this question we are given the following parameters or data or information which is going to assist us in solving the question efficiently and they are;

(1). "500 VAR reactive power from 230 Vrms 50 Hz 1.5 KVAR reactor".

(2). Consideration of up to 12th harmonic.

So, let us delve right into the solution to the question above;

Step one: Calculate the Irms and Irms(12th) by using the formula for the equation below;

Irms = reactive power /Vrms = 500/230 = 2.174 A.

Irms(12th) = 1.5 × 10^3/ 12 × 230 = 0.543 A.

Step two: Calculate the THD.

Before the Calculation of the THD, there is the need to determine the value for the dissociation factor, h.

h = Irms(12th)/Irms = 0.543/ 2.174 = 0.25.

Thus, THD = [1/ (h)^2 - 1 ] ^1/2. = 3.873.

THD % = 3.873 × 100 = 387.3%.

Step four: angle AC - Ac converter

theta = sin^-1 (1.5 × 10^3/ 12 × 500) = 14.5°.

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print: 1. The printer's electronic circuits must be energized. 2. Paper must be loaded and ready to advance. 3. The printer must be "on line" with the microprocessor. As each of the above conditions is satisfied, a HIGH is generated and applied to a 3-input logic gate. When all three conditions are met, the logic gate produces a HIGH output indicating readiness to print. The basic logic gate used in this circuit would be an): A) NOR gate. B) NOT gate. C) OR gate. D) AND gate.

Answers

Answer:

D) AND gate.

Explanation:

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met  the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

A shaft consisting of a steel tube of 50-mm outer diameter is to transmit 100 kW of power while rotating at a frequency of 34 Hz. Determine the tube thickness that should be used if the shearing stress is not to exceed 60 MPa.

Answers

Answer:

25 - \(\sqrt[4]{26.66*10^{-8} }\)  mm

Explanation:

Given data

steel tube : outer diameter = 50-mm

power transmitted = 100 KW

frequency(f) = 34 Hz

shearing stress ≤ 60 MPa

Determine tube thickness

firstly we calculate the ; power, angular velocity and torque of the tube

power = T(torque) * w (angular velocity)

angular velocity ( w ) = 2\(\pi\)f = 2 * \(\pi\) * 34 = 213.71

Torque (T) = power / angular velocity = 100000 / 213.71 = 467.92 N.m/s

next we calculate the inner diameter  using the relation

  \(\frac{J}{c_{2} } = \frac{T}{t_{max} }\)  = 467.92 / (60 * 10^6) =  7.8 * 10^-6 m^3

also

c2 = (50/2) = 25 mm

\(\frac{J}{c_{2} }\) = \(\frac{\pi }{2c_{2} } ( c^{4} _{2} - c^{4} _{1} )\) =  \(\frac{\pi }{0.050} [ ( 0.025^{4} - c^{4} _{1} ) ]\)

therefore; 0.025^4 - \(c^{4} _{1}\) = 0.050 / \(\pi\) (7.8 *10^-6)

\(c^{4} _{1}\) = 39.06 * 10 ^-8 - ( 1.59*10^-2 * 7.8*10^-6)

    39.06 * 10^-8 - 12.402 * 10^-8 =26.66 *10^-8

\(c_{1} = \sqrt[4]{26.66 * 10^{-8} }\)  =

THE TUBE THICKNESS

\(c_{2} - c_{1}\) = 25 - \(\sqrt[4]{26.66*10^{-8} }\)  mm

Find the magnitude of the two forces, such that if they act at right angles their resultant is √10N But if they act at 60°, their resultant is √13 N​

Answers

Note that  the magnitudes of the two forces are F1 = √6 N and F2 = 2 N.

What is the explanation for the above response?

Let F1 and F2 be the magnitudes of the two forces. If they act at right angles, their resultant R is given by:

R = √(F1^2 + F2^2)

If they act at 60 degrees, their resultant R' is given by:

R' = √(F1^2 + F2^2 + 2F1F2cos60°) = √(F1^2 + F2^2 + F1F2)

We can set up a system of equations to solve for F1 and F2:

√(F1^2 + F2^2) = √10 ...(1)

√(F1^2 + F2^2 + F1F2) = √13 ...(2)

Squaring both sides of equation (1), we get:

F1^2 + F2^2 = 10

Squaring both sides of equation (2), we get:

F1^2 + F2^2 + F1F2 = 13

Substituting F1^2 + F2^2 = 10 from equation (1), we get:

10 + F1F2 = 13

F1F2 = 3

Now, we can solve for F1 and F2 using the equations:

F1^2 + F2^2 = 10

F1F2 = 3

Multiplying the second equation by 4, we get:

4F1F2 = 12

Substituting F1F2 = 3, we get:

12 = 3(F1^2 + F2^2)

Simplifying, we get:

F1^2 + F2^2 = 4

Using this equation and F1F2 = 3, we can solve for F1 and F2:

F1^2 + F2^2 = 4

F1F2 = 3

Multiplying the first equation by F1F2, we get:

F1^2F2 + F1F2^2 = 12

Substituting F1F2 = 3, we get:

F1^2 + 3F2^2 = 12

Substituting F1^2 = 4 - F2^2 from the first equation, we get:

4 - F2^2 + 3F2^2 = 12

Simplifying, we get:

2F2^2 = 8

F2^2 = 4

F2 = 2

Substituting F2 = 2 in F1^2 + F2^2 = 10, we get:

F1^2 + 4 = 10

F1^2 = 6

F1 = √6

Therefore, the magnitudes of the two forces are F1 = √6 N and F2 = 2 N.

A hot horizontal plate is insulated on one side. which of the placement will allow the hot surface to cool faster?

Answers

Placing the insulated side of the hot horizontal plate facing upwards will allow it to cool faster.

When the insulated side of the plate is facing upwards, the hot surface is exposed to the surrounding air, allowing for more efficient heat transfer through convection. As the hot air rises, it carries away the heat from the plate, promoting faster cooling. Additionally, the upward-facing insulated side prevents heat from being trapped and reflected back onto the plate, further enhancing the cooling process.

On the other hand, if the insulated side is facing downwards, heat transfer through convection is hindered. The insulated surface blocks the direct contact between the plate and the surrounding air, reducing the effectiveness of convective heat transfer. Heat is retained near the plate, leading to slower cooling.

In summary, placing the insulated side of the hot horizontal plate facing upwards promotes better convection and faster cooling by allowing direct contact with the surrounding air. Conversely, placing the insulated side facing downwards hinders convective heat transfer, resulting in slower cooling.

You are working on a residential heat pump. The heat pump is connected to a
240-V, 60-Hz power line. The compressor has a current draw of 34 amperes when operating. The compressor has a power factor of 70%. The backup strip heat is
rated at 10 kW. You need to know the amount of total current draw that will occur if
the strip heat comes on while the compressor is operating.

Answers

The amount of total current draw that will occur if the strip heat comes on while the compressor is operating is 53.778 A.

How to find the total current

We have the following details

Pe = 10 Kw

compressor current = 34A

Power factor = 70%

The voltage applied = 240 V

frequency f = 60 Hz

P = ER² / R

= 240² / 10 x 10

= 57600 / 10000

= 5.76Ω

We have El = Lr = Et

El = Lr = 240

The true power P

10 x 10³ / 240

= 41.667 A

The total current is solved by

√41.667² + 34³

= √1736.138 + 1156

= √2892.138

= 53.778 A

Hence the amount of total current draw that will occur if the strip heat comes on while the compressor is operating is 53.778 A.

Answers

Press fit power steering pump pulleys require a special puller to remove the pulley, according to Technician A. In contrast, Technician B claims that the power steering pump pulley should be mounted in a vice to press the pulley off the pump.

As a result, both technicians have different opinions on the best way to remove the power steering pump pulley. However, it should be noted that Technician A is correct.A press-fit pulley is one that is installed by pressing it onto a power steering pump shaft. Because the pulley is affixed to the pump shaft, it can be challenging to remove without causing damage. To accomplish this task, a press-fit pulley remover tool is required. The tool attaches to the pump shaft and then connects to the pulley's hub.

The tool will extract the pulley from the shaft as the nut is tightened.Typically, if you try to remove a press-fit pulley by using a vice, you can harm it. When using a vice, the pulley will be ruined, which is why Technician B is incorrect. In addition, attempting to pry off the press-fit pulley with a pry bar or a screwdriver will cause damage to the power steering pump shaft.In summary, Technician A is correct that a press-fit power steering pump pulley requires a special puller to remove the pulley. Technician B's method of mounting the power steering pump pulley in a vice to press the pulley off the pump is incorrect.

The given problem states that the maintenance on a machine is expected to be $8257 for the second year and an additional $1,750 cost every year until year 6.

We are supposed to calculate the present equivalent value at the beginning of the first year if the interest is 4% per year.To calculate the present value of the maintenance, we will use the formula for the present value of an annuity, which is given by:PV = PMT [(1 - (1 + r)⁻ⁿ) / r]Here, PV is the present value, PMT is the payment, r is the interest rate per period, and n is the total number of periods.

To calculate the present value, we first need to calculate the total maintenance cost for years 2 to 6:Total maintenance cost for years 2 to 6 = $1,750 × 5= $8,750Now, we can calculate the present value of the maintenance cost using the formula:PV = $8257 + $8,750 / (1 + 0.04)² +  $8,750 / (1 + 0.04)³ + $8,750 / (1 + 0.04)⁴ + $8,750 / (1 + 0.04)⁵PV = $31,092.06Therefore, the present equivalent value at the beginning of the first year if the interest is 4% per year is $31,092.06 (rounded to 2 decimal places).

telnet and ssh are known as what type of management system

Answers

Telnet and SSH are both remote management systems that enable users to access and control remote computers over a network.

Explanation:

Telnet is a remote management system that operates on the application layer of the OSI model. It is a simple and lightweight protocol that enables users to establish a connection and interact with a remote computer using a command-line interface. However, because Telnet does not provide encryption, it is considered insecure, and data transmitted over Telnet can be intercepted and read by malicious actors.

SSH, or Secure Shell, is a more advanced remote management system that provides encryption, authentication, and data integrity. SSH encrypts all data transmitted between the client and the server, making it difficult for attackers to intercept and read sensitive information. It also provides authentication mechanisms, such as passwords and public-key cryptography, to ensure that only authorized users can access the remote computer. Additionally, SSH uses digital signatures to ensure data integrity, preventing malicious actors from altering the data in transit. As a result, SSH is considered a more secure protocol than Telnet and is widely used in modern network environments.

How much longer will it take for the average settlement to attain 237 mm? (b). Considering the parameters in Q.2., calculate the effective pressure on a horizontal plane at a depth 10
meters below the ground surface?

Answers

For the first question, the answer is that it will take approximately 0.768 years (or approximately 9.22 months) longer for the average settlement to reach 237 mm. The effective pressure on a horizontal plane at a depth of 10 meters below the ground surface is approximately 264.87 kN/m².

Here, Settlement rate = Ultimate settlement / Time

Given that the ultimate settlement is 332 mm and the time span is 3 years, the settlement rate is:

Settlement rate = 332 mm / 3 years = 110.67 mm/year

Time = (Target settlement - Average settlement) / Settlement rate

Time = (237 mm - 152 mm) / 110.67 mm/year ≈ 0.768 years

Therefore, it will take approximately 0.768 years (or approximately 9.22 months) longer for the average settlement to reach 237 mm.

b. Hence , Effective pressure = Unit weight of soil x Depth

Unit weight of soil = Specific gravity x Unit weight of water

= 2.7 x 9.81 kN/m³

≈ 26.487 kN/m³

Effective pressure = Unit weight of soil x Depth

= 26.487 kN/m³ x 10 m

= 264.87 kN/m²

Therefore, the effective pressure on a horizontal plane at a depth of 10 meters below the ground surface is approximately 264.87 kN/m².

In literature it is stated that in controlling of a conical tank, PID fails to give fast response because of the non-linearity present in the system. What other type of the controlling methods proposed in the literature? Summarize 1 research article published in one of the peer-reviewed journals. Explain their approach briefly.

Answers

Model Predictive Control (MPC) is a control model of a conical tank.

MPC is a control method. It uses a mathematical model of the system to predict its future behavior and optimize control actions accordingly. It is known for its ability to handle non-linear systems effectively.

MPC formulates an optimization problem to determine the control actions that optimize a performance criterion, subject to system constraints. The control actions are computed over a finite time horizon, but only the first control action is implemented. The optimization problem is then solved again at the next time step, taking into account the updated system state.

Explanation:

The distance between the centers of the two arms of a U-tube open to the atmosphere is 30 cm, and the U- tube contains 20-cm-high alcohol in both arms. Now the U-tube is rotated about the left arm at 4.2 rad/s. Determine the elevation difference between the fluid surfaces in the two arms.

Answers

The U-tube is rotated about the left arm at a speed of 4.2 rad/s. The distance between the centers of the two arms of the U-tube open to the atmosphere is 30 cm, and both arms contain 20-cm-high alcohol.

We need to determine the elevation difference between the fluid surfaces in the two arms.In order to determine the elevation difference between the fluid surfaces in the two arms, we'll use Bernoulli's equation as follows:P₁ + ρgh₁ + 1/2 ρv₁² = P₂ + ρgh₂ + 1/2 ρv₂²Here, P₁ and P₂ are the pressures at points 1 and 2, respectively. ρ is the density of the fluid. h₁ and h₂ are the heights of points 1 and 2, respectively. v₁ and v₂ are the velocities of the fluid at points 1 and 2, respectively. Since both the arms contain alcohol, their density is the same.

Therefore, the density term cancels out from both sides of the equation. P₁ and P₂ are atmospheric pressures, so they are also the same. We can ignore them. The velocity at point 1 is zero because it's at rest. We need to find the difference in elevation, so we can subtract h₁ from h₂.

Therefore, the equation becomes:0 + 0 + 0 = 0 + (h₂ - h₁)g + 1/2 v₂²where g is the acceleration due to gravity, and we've ignored the factor of 1/2 ρv₁² since v₁ is zero. The velocity of the fluid at point 2 can be calculated using the formula:v = ωrwhere ω is the angular velocity, and r is the radius of rotation. Since the U-tube is rotated about the left arm, the radius of rotation is 15 cm.

Therefore, v = 4.2 × 0.15 = 0.63 m/s. Substituting this value in the equation, we get:0 = (h₂ - h₁)9.8 + 1/2 (0.63)²Rearranging the terms, we get:(h₂ - h₁) = (1/2 × 0.63²)/9.8 = 0.020 mTherefore, the elevation difference between the fluid surfaces in the two arms is 0.020 m. Answer: 0.020 m.

why was tlc used why did you need to use two visualization techniques

Answers

TLC (thin-layer chromatography) was used due to its ability to separate and identify components in a mixture. Two visualization techniques were employed to enhance the detection and analysis of the separated compounds.

Why did the utilization of two visualization techniques become necessary for TLC analysis?

TLC is a powerful analytical technique used in chemistry to separate and identify different components present in a mixture. It involves the separation of compounds on a thin layer of adsorbent material, such as silica gel or alumina, using a mobile phase. To visualize the separated compounds, specific visualization techniques are employed.

The main reason for using TLC is its effectiveness in separating and identifying different compounds within a mixture. However, the visualization of the separated components is crucial for accurate analysis. Sometimes, the separated compounds may not be easily visible or distinguishable on the TLC plate. Therefore, employing multiple visualization techniques can enhance the detection and analysis of these compounds.

By using two visualization techniques, we increase the chances of detecting all the components present in the mixture. Different compounds may respond differently to each visualization technique, resulting in improved sensitivity and selectivity. Additionally, some compounds may show better contrast or fluorescence under one technique compared to another.

If an oncoming driver crosses into your path of travel, the space that is usually available for you to move your vehicle is.

Answers

Answer:

If an oncoming driver crosses into your path of travel, the space that is usually available for you to move your vehicle is to the right of your vehicle.

Explanation:

On many roads, there are areas on the sides of the road called the shoulder. The shoulder can be used for pulling over and stopping your vehicle due to emergencies.

If a driver crosses into your lane coming straight for you, the best thing to do is to pull over to the shoulder as fast as possible so to not turn left and hit incoming traffic.
