Answer:
Corps regulators now send threatening letters to farmers who switch from one crop to another, such as rice to orchards, or perform routine plowing.
Explanation:
The Corps says the farmers can be performing a “land-use” change that suddenly puts a farm under Corps jurisdiction. It is getting harder and harder, and in legal terms more dangerous, to be an American farmer these days, thanks to the aggressive behavior of the federal Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers. Increasingly, those regulations are changing at the arbitrary say-so of the Corps regulators who implement the EPA’s regulations on the ground, even though most practices followed by American farmers have been exempted from CWA prohibitions since it was written in 1977.
Why is the evaluation of a design based on data and not personal feelings?
Answer:
The Evaluation of a design is based on the data because it should be based on the effectiveness of the product and the quality. To make sure a product is functional and able to produce what it should be producing or completing the process it should be completing. Data should be unbiased because multiple people should be able to evaluate with different views as well so that there are different opinions on what should be fixed or changed so that there is not one thing that is voted on to change but many to improve the product.

The best designed saw for cutting miter joints is a
O handsaw
O backsaw
O coping saw
O hacksaw
Answer:
backsaw
Explanation:
The best designed saw for cutting miter joints is a backsaw. The correct option is 2.
What is a backsaw?Any hand saw having a stiffening rib on the edge opposite the cutting edge—known as a backsaw—enables better control and more accurate cutting than other saws.
For precise tasks like cutting dovetails, mitres, or tenons in cabinetry and joinery, backsaws are typically employed in woodworking.
Its teeth have sharp, knife-like points because they are beveled on both sides, which cuts through the fibers of the wood.
The down stroke of the crosscut saw is also used to cut. The backsaw features a small, squared-off blade that is about a foot long, and to maintain the blade straight, a sheet steel reinforcing strip is wrapped over the back of the blade.
Thus, the correct option is 2.

The purification of hydrogen gas is possible by diffusion through a thin palladium sheet Calculate the number of kilograms of hydrogen that pass per hour (in kg/h) through a 4.6 mm thick sheet of palladium having an area of 0.25 m² at 500°C. Assume a diffusion coefficient of 6.0 x 10^-8 m^2/s, that the concentrations at the high and low-pressure sides of the plate are 5.2 and 0.32 kg/m^3 (kilogram of hydrogen per cubic meter of palladium), and that steady-state conditions have been attained.
The number of kilograms of hydrogen that pass per hour (in kg/h) through is equal to 0.0573 kg/h.
What is Diffusion?The diffusion of material is the movement of action atoms for the region from high to low concentration. In other words, it is the transportation of material from atomic movement dependent on time.
There are different types of mechanism diffusion: interstitial diffusion and substitutional diffusion.
The diffusion can be explained by the Fick Law (Fick's 1st Law and Fick's 2nd Law). For solving you should apply Fick's 1st Law, which says:
M=JAt=[tex]-DAt\frac{ \Delta C }{\Delta X}[/tex]., where:
D= diffusion coefficientA = area t= time ΔC/ΔX = the concentration of the gradient x= thickness sheetThe exercise asks the number of kilograms of hydrogen that pass per hour (in kg/h), and it gives:
D= diffusion coefficient= 6.0 x 10^-8 m²/sA = area = 0.25 m² ΔC= 0.32 - 5.2 kg/m^3 x= [tex]4.6*10^{-3} m[/tex]Thus,
[tex]-(6.0* 10^{-8} m^2/s)*0.25 m^2*(\frac{3600*s}{h} )*(\frac{0.32-5.2 kg/m^3}{4.6*10^-3 m} )= 0,0573 \frac{kg}{h}[/tex]

One integrated circuit design calls for the diffusion of arsenic into silicon wafers; the background concentration of As in Si is 2.5 x 1020 atoms/m. The predeposition heat treatment is to be conducted at 1000°C for 45 minutes, with a constant surface concentration of 8x 10^26 As atoms/m³. At a drive in temperature of 1100°C, determine the diffusion time required for a junction depth of 1.21m. For this system, values of Q and Do are 4.10 eV and 2.29x10^3m/s, respectively.
The diffusion time that is needed for the junction depth of 1.21 m is given as 13875 seconds
How to solve for the diffusion timebackground concentration of As in Si is 2.5 x 10²⁰ atoms/m
tp = 1000°c
tp = 45 minutes
= 45 x 60 seconds
surface concentration = 8x 10^26
Td = 1100°c
Junction depth = 1.2
= 1.2 x 10⁻⁶m
qd = 4.10ev
Do = 2.29 x 10⁻³
We have to use the equation
[tex]Dp = Doexp(-\frac{qd}{kTP} )\\\\= (2.23 * 10^-^1^3 m^2/s) exp [-\frac{4.10}{8.62*10^-^5 *(1000+273)} ][/tex]
= 1.36 x 10⁻¹³
From the relation that we have here
[tex]Qo = 2cs\sqrt{\frac{Dpte}{pi} } \\\\= 2 * 8* 10^2^6*\sqrt{\frac{1.36*10^-^1^3(45*60)}{pi} }[/tex]
Qo = 1.73 x 10¹³
Dd at 1100
[tex]Dd = 2.29*10^-^3exp(\frac{-4.10}{8.62x10^-^5)(1100 + 273)}[/tex]
Dd = 2.06 x 10⁻¹⁸m²/s
From the relation we have
[tex]exp[\frac{(1.2 * 10^-^6)^2}{4*(2.06x10^-^1^8)+d} ]=\frac{1.73*10^1^9}{2.5x10^2^0*\sqrt{pi*2.06*10^-^1^8x+d} }[/tex]
[tex]ln\frac{2.72*10^7}{\sqrt{+d} } =\frac{1.75*10^5}{+d}[/tex]
Using heat and trial, we would have the value of +d = 13875 seconds

How to explain Bernoulli experiment in the paper tent in full sentences
According to Bernoulli's principle, as the velocity of liquid increases, the pressure decreases.
Ventilation under the folds of the paper, therefore, increases the wind speed.
This speed increase leads to a decrease in pressure. This means that there are fewer air molecules in this space than before.
What caused the tent to collapse? Everything in nature seeks balance. If there is a place with low pressure, air will enter from a place with high pressure, and the pressure will become uniform again.
In our case, the air above the tent was more condensed when it was blown out from under the tent. The air, trying to equalize the pressure, pushed against the tent and it toppled.
With the lid underneath, the high-pressure overhead will cause the tent to collapse.
Why does the pressure increase as speed increases? The answer lies in the concept of conservation of energy. That is, points in the system is neither designed nor distributed and are only passed between types.
There are different types of energy, but this science assumes kinetic or kinetic energy and pressure energy.

What is a Fluid Power system?A pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor does work in fluid power systems. A fluid cylinder generates force, which results in linear motion, whereas a fluid motor generates torque, which results in rotating motion.
Fluid power may be utilized for exceedingly difficult work like drilling new underground mining tunnels, as well as very gentle operations like lifting and stacking enormous sheets of glass. Fluid power systems may push, pull, lift, twist, or grasp practically any load using different components and actuators.
Fluid power systems are classified into two types: hydraulic equipment, which use liquids such as water and oil, and pneumatic systems, which use neutral gases such as air.
