Handsaw teeth are very sharp: to avoid being cut by the teeth, keep hands and fingers well away from the
path of the blade
Answer:
(a) Current density at P is 
.
(b) Total current I is 3.257 A
Explanation:
Because question includes symbols and formulas it can be misunderstood. In the question current density is given as below;
where 
and 
unit vectors.
(a) In order to find the current density at a specific point <em>(P)</em>, we can simply replace the coordinates in the current density equation. Therefore
(b) Total current flowing outward can be calculated by using the relation,
where integral is calculated through the circular band given in the question. We can write the integral as below,
due to unit vector multiplication. Then,
where 
. Therefore
Explanation:
The four primary materials used for bridges have been wood, stone, iron, and concrete. Of these, iron has had the greatest effect on modern bridges. Steel is used to make reinforced and prestressed concrete. Modern bridges are almost exclusively built with steel, reinforced concrete, and prestressed concrete.
Wood and Stone: Wood is relatively weak in both compression and tension, but it has almost always been widely available and inexpensive. Civil Engineers now incorporate laminated wooden beams and arches into some modern bridges.
Stone is strong in compression but weak in tension. Its primary application has been in arches, piers, and abutments.
Iron and Steel: Cast iron is strong in compression but weak in tension. Wrought iron has much greater tensile strength. Steel is superior to any iron in both tension and compression. Steel can be made to varying strengths, some alloys being five times stronger than others. The civil engineer refers to these as high-strength steels.
Concrete: Concrete is an artificial stone made from a mixture of water, sand, gravel and cement. It is strong in compression and weak in tension. Concrete with steel bars embedded in it is called reinforced concrete. Reinforcement allows for less concrete to be used because the steel carries all the tension; also, the concrete protects the steel from corrosion and fire.
An object can be described by using it's features.These are the physical features of the faucet.
Most object or things do have a lot of observable properties. These are: weight, size, shape, color, etc.
The Physical properties of an object consist of the shape, size, materials, etc. The Physical attributes is used to describe how the outcome of an object looks and feels. In the case of the faucet, it is a stainless steel with long arc.

Answer:
Rule of Law
Explanation:
Selective Incorporation can be defined as the law that has been laid down which prevents state government from creating or making laws that can affect or withdraw the rights of citizens or people in America.
The Rule of Law can be defined as the law that makes every American citizen, including the American government equal in the sight of the law. The rule of law also serves to regulate the inappropriate use of power by the people or individuals on the seat of authority.
Therefore, the concept of the "selective incorporation" supports the government principles of Rule of law because it regulates the power of state governments and prevents them from using their powers to take away or hinder the rights of the American citizens.
