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.

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.

Because Rafael is concerned about building materials entering the marketplace that are marketed as sustainable or renewable but that isn't really any such thing, Rafael of Incipient Renewable Construction creates a consumer watchdog group to identify such products.

Rafael's efforts which can be described as consumer advocacy will be most effective at improving:

Consumer confidence surveys are important measures of the economy's overall health. When people are secure in the consistency of their earnings, it affects their spending and saving habits.

A Consumer Watchdog organization's responsibilities include the following:

Conduct educational and research initiatives, as well as litigation, on consumer and public interest problems, including, but not limited to, consumer safety and government reform, and make the results of such research available to the public.

Answer:

backsaw

Explanation:

The best designed saw for cutting miter joints is a backsaw. The correct option is 2.

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.

Given that Gavin is designing a device that must rely on precise movements. It must have the force to cut through metal yet be safe enough for one person to hold steady on his or her own. The type of power system should Gavin use to create the device in the following scenario is: " a fluid power system similar to one used in a pool pump" (Option A)

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.
