The first step in representing entities using the relational model is to A) define a table for each entity.

Identifiers, also known as primary keys, play a crucial role in the relational model as they uniquely identify each instance of an entity within a table. The primary key ensures that each row in the table is uniquely identifiable, allowing for efficient data retrieval and data integrity.

When representing entities using the relational model, it is essential to identify the attributes that uniquely distinguish each entity instance. These attributes serve as the primary key of the table associated with the entity. The selection of the primary key is based on the specific characteristics of the entity and its requirements.

By determining identifiers as the first step, one establishes the foundation for creating tables that represent entities accurately and effectively. The primary key sets the stage for defining relationships between entities, enforcing referential integrity, and ensuring data consistency within the database.

Answer:

Critical Flaw Length=17.08 mm

The Critical flaw Length > 4mm, It means it is detectable.

Explanation:

Given Data:

Fracture Toughness=\(K_{tc}\)=88MPa

Yield Strength=σ=710 MPa

Y=1.07

Solution:

Formula:

\(Critical\ Length=\frac{1}{\pi } *(\frac{K_{tc}}{Y*\sigma} )^2\)

Since yield Strength is half, Critical Length will be:

\(Critical\ Length=\frac{1}{\pi } *(\frac{K_{tc}}{\frac{\sigma}{2} *Y} )^2\\Critical\ Length=\frac{1}{\pi } *(\frac{88MPa}{\frac{710MPa}{2} *1.07} )^2\\\\Critical\ Length=0.01708\ m\)

Critical Flaw Length=17.08 mm

The Critical flaw Length > 4mm, It means it is detectable.

Answer:

the rate of flow = 29.28 ×10⁻³ m³/s or 0.029 m³/s

Explanation:

Given:

Diameter of the pipe = 100mm = 0.1m

Contraction ratio = 0.5

thus, diameter at the throat of venturimeter = 0.5×0.1m = 0.05m

The formula for discharge through a venturimeter is given as:

Where,

is the coefficient of discharge = 0.97 (given)

A₁ = Area of the pipe

A₁ =  

A₂ = Area at the throat

A₂ =  

g = acceleration due to gravity = 9.8m/s²

Now,

The gauge pressure at throat = Absolute pressure - The atmospheric pressure

⇒The gauge pressure at throat = 2 - 10.3 = -8.3 m (Atmosphric pressure = 10.3 m of water)

Thus, the pressure difference at the throat and the pipe = 3- (-8.3) = 11.3m

Substituting the values in the discharge formula we get

or

or

Q = 29.28 ×10⁻³ m³/s

Hence, the rate of flow = 29.28 ×10⁻³ m³/s or 0.029 m³/s

The Negative battery cable is used to bolt the vehicle frame to allow the metal structure of the vehicle to serve as a large conductor to carry current.

Explanation:

Battery cable is large automotive cable. Like smaller types of automotive wire, it is available in PVC and cross-linked forms. Click here to read an earlier post explaining the differences between PVC and cross-linked wire insulation.

One type of PVC battery cable is SGT cable. It is rated to 80°C and therefore can be used in starters or battery grounds.  Cross-linked battery cables can also be used in starter and battery ground applications, and they are more resistant to heat, abrasion, and aging than PVC cable.

Two types of cross-linked battery cable are SGX and STX. They are rated to 125°C. Of the three types of battery cable (SGT, SGX, amd STX), STX has the thinnest wall, making it a popular choice for automotive applications with limited space.

Answer:

2)

a)  to the right of the dipole    E_total = kq [1 / (r + a)² - 1 / r²]

b)To the left of the dipole      E_total = - k q [1 / r² - 1 / (r + a)²]

c) at a point between the dipole, that is -a <x <a  

      E_total = kq [1 / x² + 1 / (2a-x)²]

d) on the vertical line at the midpoint of the dipole (x = 0)

E_toal = 2 kq 1 / (a ​​+ y)² cos θ

Explanation:

2) they ask us for the electric field in different positions between the dipole and a point of interest. Using the principle of superposition.

This principle states that we can analyze the field created by each charge separately and add its value and this will be the field at that point

Let's analyze each point separately.

The test charge is a positive charge and in the reference frame it is at the midpoint between the two charges.

a) to the right of the dipole

The electric charge creates an outgoing field, to the right, but as it is further away the field is of less intensity

           E₊ = k q / (r + a)²

where 2a is the distance between the charges of the dipole and the field is to the right

the negative charge creates an incoming field of magnitude

           E₋ = -k q / r²

The field is to the left

therefore the total field is the sum of these two fields

           E_total = E₊ + E₋

           E_total = kq [1 / (r + a)² - 1 / r²]

we can see that the field to the right of the dipole is incoming and of magnitude more similar to the field of the negative charge as the distance increases.

b) To the left of the dipole

The result is similar to the previous one by the opposite sign, since the closest charge is the positive one

E₊ is to the left and E₋ is to the right

          E_total = - k q [1 / r² - 1 / (r + a)²]

We see that this field is also directed to the left

c) at a point between the dipole, that is -a <x <a

In this case the E₊ field points to the right and the E₋ field points to the right

                      E₊ = k q 1 / x²

                      E₋ = k q 1 / (2a-x)²

                      E_total = kq [1 / x² + 1 / (2a-x)²]

in this case the field points to the right

d) on the vertical line at the midpoint of the dipole (x = 0)

    In this case the E₊ field points in the direction of the positive charge and the test charge

    in E₋ field the ni is between the test charge and the negative charge,

the resultant of a horizontal field in zirconium on the x axis (where the negative charge is)

                      E₊ = kq 1 / (a ​​+ y) 2

                      E₋ = kp 1 / (a ​​+ y) 2

                      E_total = E₊ₓ + E_{-x}

                      E_toal = 2 kq 1 / (a ​​+ y)² cos θ

e) same as the previous part, but on the negative side

                        E_toal = 2 kq 1 / (a ​​+ y)² cos θ

When analyzing the previous answer there is no point where the field is zero

The different configurations are outlined in the attached

3) We are asked to repeat part 2 changing the negative charge for a positive one, so in this case the two charges are positive

a) to the right

in this case the two field goes to the right

           E_total = kq [1 / (r + a)² + 1 / r²]

b) to the left

            E_total = - kq [1 / (r + a)² + 1 / r²]

c) between the two charges

E₊ goes to the right

E₋ goes to the left

            E_total = kq [1 / x² - 1 / (2a-x)²]

d) between vertical line at x = 0

E₊ salient between test charge and positive charge

           E_total = 2 kq 1 / (a ​​+ y)² sin θ

In this configuration at the point between the two charges the field is zero

a The natural frequency of the paralysis transient response is 1.07 rad/s.

b The maximum possible percent paralysis if a 2% mixture of isoflurane is used is 7.63%.

c  The step response of paralysis if a 1% mixture of isoflurane is used

The percent isoflurane that would have to be used for 100% paralysis is 27.3%.

A. The damping ratio is given by ζ = −b/2√(a² - c²).

In this case, a = 1.15, b = 0, and c = 0.28,

The natural frequency of the paralysis transient response is given by ωn = √(a² - c²)

= √(1.15² - 0.28²)

= 1.07 rad/s.

B. The maximum possible percent paralysis is given by the steady-state value of the step response. In this case, the steady-state value is equal to the gain of the system, which is 7.63 × 10⁻².

Therefore, the maximum possible percent paralysis if a 2% mixture of isoflurane is used is 0.0763 = 7.63%.

C. The step response of paralysis if a 1% mixture of isoflurane is used is shown below.

Time (s) | Percent paralysis

------- | --------

0.0 | 0.00

0.1 | 0.03

0.2 | 0.06

0.3 | 0.09

0.4 | 0.12

0.5 | 0.15

0.6 | 0.18

0.7 | 0.21

0.8 | 0.24

0.9 | 0.27

1.0 | 0.30

As you can see, the percent paralysis increases rapidly at first, and then approaches a steady-state value of

= 7.63 × 10⁻²

= 7.63%.

D. For 100% paralysis, the percent paralysis must equal the gain of the system, which is 7.63 × 10⁻². Therefore, the percent isoflurane that would have to be used for 100% paralysis is

= 0.63 × 10⁻² / 0.28
