I just did the assignment on EDGE2020 and it's 200% correct!  

Also, heart and rate if you found this answer helpful!! :) (P.S It makes me feel good to know I helped someone today!!)  :)  

Answer:

zero off your workpiece so you can work from a datum, usually the centre of your work on a lathe. change your tool to a drill and drill a hole to a size smaller than your thread diameter, change out your tool for a threaded tap and away you go.

I'm not sure which part they want but I'd say ensure your tool is set to the right height, you have the tool lines up where you want to cut and that you have calculated the speed you need to cut at safety. Drill a hole before you tap though.

If you have a CNC lathe you just set the programme to do the processes and tool change for you.

The first step to cutting internal threads on an engine lathe is to make calculations so that the thread will have proper dimensions.

The technique of thread cutting on the lathe results in a helical ridge with a consistent section on the workpiece.

To work from a datum, often the center of your work on a lathe, zero off your workpiece. Use a drill to create a hole that is less in diameter than the thread, then switch to a threaded tap and carry on.

One would advise making sure your tool is adjusted to the appropriate height, that it is lined up where you want to cut, and that you have determined the speed you must cut in order to be safe. Before you tap, drill a hole.

With a CNC lathe, you can simply program the machine to perform the processes and tool changes for you.

Therefore,  to do this, make a series of cuts with a threading toolkit that matches the needed thread form.

It's the law. Under New York law, you can get a citation for riding your bike while listening to music using headphones or earbuds in both ears. It is lawful, however, to listen to music with only one earbud keeping the other ear free.

Sensory deprivation. One of the main ways that people alert each other to danger on the road is through sound. Whether it's honking, yelling or ringing a bicycle bell, you're less likely to hear any of these warnings if you're listening to music putting you at higher risk of an accident.

Decreased attention. The more stimuli you have to contend with, the more difficult it is to dedicate your full attention to one particular task. If you get caught up in a song or story you're listening to while cycling, it can increase your distractibility which could have disastrous consequences.

The majority of cycling-related accidents involve a cyclist and a motor vehicle. Not surprisingly, the injuries a cyclist suffers in such collisions tend to be disproportionately serious and often fatal. Therefore, if you're cycling in traffic, foregoing the headphones can prove to be a life-saving decision.

Answer:

  infinite

Explanation:

The impedance of an ideal parallel resonant circuit is infinite at the resonant frequency. The sum of the admittances of the branches of the circuit is zero.

The minimum value of the interval is two standard deviations below the mean (μ - 2σ), while the maximum value of the interval is two standard deviations above the mean (μ + 2σ).

The range rule of thumb states that the usual measures in an interval are within two standard deviations of the mean.

The parameters you are given to solve this problem are:

Mean μ.

Standard deviation σ.

Hence the lower bound of the interval is of:

μ - 2σ -> you should subtract two standard deviations from the mean.

The upper bound of the interval is of:

μ + 2σ -> you should add two standard deviations to the mean.

Therefore, The minimum value of the interval is two standard deviations below the mean (μ - 2σ), while the maximum value of the interval is two standard deviations above the mean (μ + 2σ).

Both technicians are partially correct, but neither of them is entirely accurate.

The expansion valve does play a role in preventing the evaporator from freezing, but it is not the only component responsible for this task. The expansion valve regulates the flow of refrigerant into the evaporator, which helps to maintain the proper temperature and pressure in the system. On the other hand, cycling the clutch also plays a role in preventing the evaporator from freezing, but it is not the primary mechanism. The clutch engages and disengages the compressor, which regulates the pressure in the refrigeration system. When the pressure drops too low, the evaporator can freeze. Therefore, both technicians are partially correct. However, a combination of various components such as the expansion valve, cycling clutch, and other controls is needed to prevent the evaporator from freezing.

Yes, in a thermocouple-extension wire junction, it is essential to connect carefully to avoid large errors because any small changes in the connection can lead to significant temperature measurement errors.

The thermocouple generates a small voltage, which is measured by the extension wire, and any disruption or variation in the connection can alter the signal and lead to incorrect readings.

This is particularly important in high-precision temperature measurements, where even small errors can have a significant impact on the results.

Furthermore, the extension wire and thermocouple wires may have different materials and electrical properties, and any poor connections can cause changes in the resistance, which can affect the signal.

Therefore, it is crucial to ensure that the connection is stable and secure, and that the wires are correctly matched and connected with minimum resistance. Any misconnections or poor contacts can lead to measurement errors, which can impact the quality and reliability of the temperature readings.

A Type I error is committed when the null hypothesis is true, but we reject it. In other words, we falsely conclude that there is a significant difference or relationship between the variables being studied when there is not.

This error is also known as a "false positive." It is important to avoid Type I errors because they can lead to incorrect conclusions and wasted resources. To prevent Type I errors, researchers typically set a predetermined level of significance (alpha level) for their study. This helps them decide whether to reject the null hypothesis or not. If the p-value (probability of obtaining results as extreme or more extreme than the observed results, assuming the null hypothesis is true) is lower than the alpha level, then the null hypothesis is rejected. However, if the p-value is higher than the alpha level, then the null hypothesis is not rejected. In summary, Type I errors occur when we falsely reject the null hypothesis, which can lead to incorrect conclusions. Researchers can prevent Type I errors by setting an alpha level and using statistical tests to determine whether to reject the null hypothesis or not.

Answer:

A) For a double drainage system the time taken for total settlement will differ from that of a single drainage system, because in a double drainage case clay water escapes from both sides unlike in a single drainage case. hence water and air will be be expulsed faster for a double drainage making it attain  total settlement faster.

B) for only single = 12 years

Explanation:

Given data :

ultimate clay settlement = 32 cm

settlement of clay in 3 years = 7.5 cm

Cv ( coefficient of consolidation ) =  1.5 x 10^-4 cm^2 /s

A) For a double drainage system the time taken for total settlement will differ from that of a single drainage system, because in a double drainage case clay water escapes from both sides unlike in a single drainage case. hence water and air will be be expulsed faster for a double drainage making it attain  total settlement faster.

note : Total settlement is the same in both drainage system.

B) Determine how long it will take for 7.5 cm of settlement to occur if there is only single

applying the relation  below

Tv = Cv t / H^2

where Tv = time factor , d = thickness of layer , H = drainage path

Given that Tv and Cv are constant in both cases

t ∝ H^2   hence

\(\frac{t1}{t2} = \frac{H^21}{H^22}\)  ------ ( 1 )

t1 = time for single drainage for d meters , t2 = time for double drainage  for d meters

equation 1 can be rewritten as

t1/t2 = d^2 / (d/2)^2

∴ t1 = 4t2

given that t2 = 3 years ( value gotten from question )

t1 = 4 * 3 = 12 years

The molecular weight will be "28.12 g/mol".

Explanation:

The given values are:

Pressure,

P = 10 atm

  = \(10\times 101325 \ Pa\)

  = \(1013250 \ Pa\)

Temperature,

T = 298 K

Mass,

m = 11.5 Kg

Volume,

V = 1000 r

   = \(1 \ m^3\)

R = 8.3145 J/mol K

Now,

By using the ideal gas law, we get

⇒ \(PV=nRT\)

o,

⇒ \(n=\frac{PV}{RT}\)

By substituting the values, we get

       \(=\frac{1013250\times 1}{8.3145\times 298}\)

       \(=408.94 \ moles\)

As we know,

⇒ \(Moles(n)=\frac{Mass(m)}{Molecular \ weight(MW)}\)

or,

⇒        \(MW=\frac{m}{n}\)

                   \(=\frac{11.5}{408.94}\)

                   \(=0.02812 \ Kg/mol\)

                   \(=28.12 \ g/mol\)

A tuple is a generalization of a pair. A pair is a collection of two elements, whereas a tuple is a collection of n elements, where n could be any natural number. A tuple can also contain two elements and function as a pair. However, a pair can’t hold more than two elements.

The term “generalization” refers to a higher level of abstraction and generality than the original concept. It can be described as a more inclusive abstraction that includes more specific instances. In this case, the tuple is more general than a pair, as it can contain any number of elements.

A pair is a mathematical structure that consists of two related components. The components in a pair could be any type of data, such as numbers, strings, or other pairs. Pairs can be used to represent ordered pairs, which are commonly used in algebra and geometry.A tuple is a mathematical structure that can store a collection of related elements.
