Composite primary keys are used in database systems when a single column is not sufficient to uniquely identify a record. Many-to-Many Relationships, Multitenancy & Historical Data.

Here are three cases where composite primary keys are commonly used:

1. Many-to-Many Relationships: In situations where there is a many-to-many relationship between two entities, a composite primary key can be used to create a junction table. For example, consider a database for a university where students can enroll in multiple courses, and each course can have multiple students. The junction table linking students and courses would typically have a composite primary key consisting of the student ID and course ID, ensuring uniqueness for each enrollment.

2. Multitenancy: In a multitenant system, where multiple clients or organizations share the same database, a composite primary key can be employed to differentiate records belonging to different tenants. For instance, in a software-as-a-service (SaaS) platform serving multiple companies, a composite primary key could include both the tenant ID and a unique identifier for each record, ensuring data isolation and preventing conflicts between different tenants.

3. Historical Data: When dealing with historical data, a composite primary key can be used to maintain the uniqueness of records across different time periods. For example, consider a sales database that tracks product prices over time. To ensure uniqueness, a composite primary key consisting of the product ID and a timestamp can be used. This allows the database to store multiple price records for the same product at different points in time, without violating primary key constraints.

In summary, composite primary keys are useful in scenarios involving many-to-many relationships, multitenancy, and historical data. They allow for the unique identification of records that cannot be achieved with a single column primary key. Whether it's managing enrollments in a university system, segregating data in a multitenant application, or storing historical records, composite primary keys provide a practical solution for maintaining data integrity and avoiding conflicts.

The local isentropic stagnation conditions in front of the shock and estimate the stagnation pressure sensed by the pitot tube.

a) To evaluate the local isentropic stagnation conditions in front of the shock, we can use the isentropic relations for a perfect gas. The isentropic relations relate the properties of a gas across a shock wave. Given the altitude of 12 km and the provided pressure and temperature of the surrounding air (19.4 kPa and -56.45 °C), we can calculate the local isentropic stagnation conditions.

First, we need to convert the temperature from Celsius to Kelvin:

T = -56.45 °C + 273.15 = 216.7 K

Using the ideal gas equation, we can calculate the density of the surrounding air:

ρ = P / (R * T)

Where P is the pressure, R is the specific gas constant, and T is the temperature.

For air, the specific gas constant R is approximately 287 J/(kg·K).

ρ = 19.4 kPa / (287 J/(kg·K) * 216.7 K)

After performing the calculation, we obtain the density of the surrounding air.

Now, using the isentropic relations, we can determine the isentropic stagnation conditions ahead of the shock. These conditions can be obtained by relating the Mach number (M) and the local conditions (P, ρ, T) to the isentropic stagnation conditions (P0, ρ0, T0).

The specific heat ratio (gamma) for air is approximately 1.4.

M0 = M * √(γ * R * T0 / (2 * γ * R * T))

Where M0 is the isentropic Mach number and T0 is the isentropic stagnation temperature.

Using this equation, we can solve for T0 and calculate the isentropic stagnation temperature.

Similarly, we can calculate the isentropic stagnation pressure (P0) using the relation:

P0 = P * (1 + ((γ - 1) / 2) * M^2)^(γ / (γ - 1))

By substituting the known values, including the calculated density (ρ), pressure (P), and temperature (T), we can obtain the isentropic stagnation pressure sensed by the pitot tube.

b) To estimate the stagnation pressure sensed by the pitot tube, we can consider that the pitot tube measures the stagnation pressure, which is the total pressure (P0) ahead of the shock. Therefore, the calculated isentropic stagnation pressure (P0) from part a) represents the stagnation pressure sensed by the pitot tube.

By following these calculations, we can evaluate the local isentropic stagnation conditions in front of the shock and estimate the stagnation pressure sensed by the pitot tube.

Answer:

Resistance of copper = 1.54 * 10^18 Ohms

Explanation:

Given the following data;

Length of copper, L = 3 kilometers to meters = 3 * 1000 = 3000 m

Resistivity, P = 1.7 * 10^8 Ωm

Diameter = 0.65 millimeters to meters = 0.65/1000 = 0.00065 m

\( Radius, r = \frac {diameter}{2} \)

\( Radius = \frac {0.00065}{2} \)

Radius = 0.000325 m

To find the resistance;

Mathematically, resistance is given by the formula;

\( Resistance = P \frac {L}{A} \)

Where;

First of all, we would find the cross-sectional area of copper.

Area of circle = πr²

Substituting into the equation, we have;

Area  = 3.142 * (0.000325)²

Area = 3.142 * 1.05625 × 10^-7

Area = 3.32 × 10^-7 m²

Now, to find the resistance of copper;

\( Resistance = 1.7 * 10^{8} \frac {3000}{3.32 * 10^{-7}} \)

\( Resistance = 1.7 * 10^{8} * 903614.46 \)

Resistance = 1.54 * 10^18 Ohms

Answer:

the projected volumetric flow rate of fuel for each of the two Dreamliner engines is 0.005 m³/s

Explanation:

Given the data in the question;

First we determine the fuel economy of Boeing 767

Range = 12,000 km

fuel capacity = 90,000 L

so,  fuel economy of Boeing 767 will be

η\(_f\) = Range / fuel capacity

η\(_f\) = ( 12,000 km / 90000 L ) ( 1000m / 1 km) ( 3.7854 L/gal × 264.2 gal/m² )

η\(_f\)  = 133,347.024 m/m³

Now, Boeing 787 is 20% more fuel efficient than Boeing 767

so fuel economy of Boeing 787 will be;

⇒ (1 - 20%) × fuel economy of Boeing 767

⇒ (1 - 0.2) × 133,347.024 m/m³

⇒ 0.8 × 133,347.024 m/m³

⇒ 106,677.6 m/m³

Hence, fuel economy of Boeing 787 dream line engine is

⇒ 106,677.6 m/m³ / 2 = 53,338.8 m/m³

Next, we find the velocity of Boeing 787

\(V_{787\) = Mach number of 787 × speed of sound

given that; Mach number is 0.85 and speed of sound is 700 mph

we substitute

\(V_{787\) = (0.85 × 700 mph) × ( 1 hr / 3600 s ) × ( 1609 m / 1 mile )

\(V_{787\) = 265.9319 m/s

Now, to get the Volume flow rate for each dream liner engine { Boeing 787 };

Volumetric flow rate = velocity of flight / fuel economy

we substitute

= 265.9319 m/s / 53,338.8 m/m³

= 0.0049857 ≈ 0.005 m³/s

Therefore,  the projected volumetric flow rate of fuel for each of the two Dreamliner engines is 0.005 m³/s

Stretching a flat, 2D shape vertically to produce a 3D item in a scene is called extrusion. For instance, extruding building polygons by a height value can result in three-dimensional building shapes.

By applying a force that causes the material to flow through an opening or die, a process known as extrusion allows a material to be plastically deformed. If the substance possesses the necessary qualities, it will adopt the cross-sectional profile of the die and keep that form in the final extrudate. The playdough toys used when playing with it are a straightforward illustration of extrusion. Playdough is forced through the die to form a certain shape, and the procedure is known as extrusion. The substance must be forced through the die firmly in order for it to produce the correct form.

The total rate of energy emission is 2786.9 W.

Radiation is a type of heat transfer where the heat energy is conveyed from photons or electromagnetic waves.  The rate of energy emission can be calculated multiplying the Stefan–Boltzmann law (σ\(*T^4\)) by area (A). Therefore, you have:

Total Rate of Energy Emission (E)= σ\(*A*T^4\), where:

σ = Stefan–Boltzmann constant = \(5.67*10^{-8}\) \(\frac{W}{m^2K^4}\)

A= area

T=temperature (K)

For solving this exercise, you should apply this formula. For your question:

σ = Stefan–Boltzmann constant = \(5.67*10^{-8}\) \(\frac{W}{m^2K^4}\)

A= 0.12 m²

T=527+273=800 K

Thus, the Total Rate of Energy Emission (E) will be:

E=σ\(*A*T^4\)

\(E=(5.67*10^{-8}\frac{W}{m^2K^4})*(0.12*m^{2} )*(800K)\\ \\ E=2786.9 W\)

The first code declares a variable called num and gives it an initial value of 0. It then enters a while loop that lauches a message box (using window.alert) to print the message "Keep going" as long as num remains less than 5.

If nothing is done within the loop to increment num towards the value 5, the loop will go on endlessly notifying the user to "Keep going".

So, an increment of 1 was added to the loop body to increment the variable num. This makes sure the loop terminates.
