Answer:

While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences. Because engineers and scientists have different objectives, they follow different processes in their work.

Explanation:

Answer:

a) 3.5 m

b) 14 secs

c) 1.4 secs

Explanation:

a)  Determine the distance the particle will travel

given velocity ( final velocity ) = 5 m/s

v^2 = u^2 + 2as

s = ( v^2 - u^2 ) / 2a

  = ( 5^2 - 8^2 ) / 2 ( -0.5 * 5^3/2 )

  = 3.5 m

b) Determine the time when v = 1m/s

V = u + at

1 = 8 + (  -0.5 * 1^3/2 ) * t

∴ t = 14 secs

c) Determine the time required for particle to travel 8 m

we will employ both equations above

V^2 = u^2 + 2as

s = 8 m , V = unknown , u = 8 m/s   back to equation

V^2 = 8^2 + 2 ( - 1/2 * V^3/2 ) * 8

∴ V^2 + 8V^3/2 - 64 = 0

resolving the above equation

V = 3.478 m/s

now using the second equation

V = u + at

3.478 = 8 + ( - 1/2 * 3.478^3/2 ) * t

hence : t = 1.4 secs

A Data Flow Diagram (DFD) is a diagram used during both the analysis and design phases of a Systems Development Life Cycle (SDLC) to document the processes of the current system or to provide a model of a proposed new system.

DFDs visually represent the flow of data within a system, illustrating how inputs are transformed into outputs through various processes and data storage components.

In the analysis phase, DFDs help to identify inefficiencies and areas for improvement in the existing system, facilitating a thorough understanding of the current processes. This is critical for identifying potential enhancements and creating a comprehensive specification for the new system.

During the design phase, DFDs serve as a blueprint for the development of the new system. They provide clear, concise visualizations of the system's architecture, ensuring that all stakeholders understand the proposed processes and their interactions. This helps streamline communication and minimize misunderstandings during the development process.

DFDs consist of several components, including external entities, processes, data stores, and data flows. External entities represent sources or destinations of data outside the system, while processes depict the transformations and operations performed on the data. Data stores are used to represent the storage of data within the system, and data flows illustrate the movement of data between components.

In summary, a Data Flow Diagram is a valuable tool used during the SDLC to effectively document, analyze, and design systems, ensuring a comprehensive understanding of both current and proposed processes.

Technologies such as bronze working first arrive in china through pastoralist nomad migrations in the Mongolian steppes.

China's culture was very different from what we conceive of today during the Bronze Age. The typical individual ate bread instead of rice and drank beer instead of tea. The ruler's influence stemmed from his kinship with the dead and his capacity to appease the gods for the sake of his people. Priests would write queries on animal bones and heat them until they cracked to discover what these beings desired. They would determine what the spirits and the ancestors desired by interpreting the fracture pattern. In order to appease them, sacrifices of wine and grains were frequently made, but in times of dire need, the Shang Dynasty kings would also offer up people and animals. As the Bronze Age progressed, the Zhou Dynasty kings phased out the practice of human sacrifice.

Complete question is:

How did technologies such as bronze working first arrive in China?

a. Through pastoralist nomad migrations in the Mongolian steppes

b. Through shipping lanes from the Korean peninsula

c. Through indigenous invention in the Yangshao culture

d. Through the overland caravan routes from the Indus Valley

Answer:

a) The mass moves a distance of 0.625 m up the slope before coming to rest

b) The distance moved by the mass when it is connected to the spring is 0.6 m

c) \(\mu = 0.206\)

Explanation:

Spring constant, k = 70 N/m

Compression, x = 0.50 m

Mass placed at the free end, m = 2.2 kg

angle, θ = 41°

Potential Energy stored in the spring, \(PE= 0.5 kx^2\)

\(PE = 0.5 * 70 * 0.5^2\\PE = 8.75 J\)

According to the principle of energy conservation

PE = mgh

8.75 = 2.2 * 9.8 * h

h = 0.41

If the mass moves a distance d from the spring

sin 41 = h/d

sin 41 = 0.41/d

d = 0.41/(sin 41)

d = 0.625 m

The mass moves a distance of 0.625 m up the slope before coming to rest

b) If the mass is attached to the spring

According to energy conservation principle:

Initial PE of spring = Final PE of spring + PE of block

\(0.5kx_1^2 = 0.5kx_2^2 + mgh\\x_2 = d - x_1 = d - 0.5\\h = d sin 41\\0.5*70*0.5^2 = 0.5*70*(d-0.5)^2 + 2.2*9.8*d*sin41\\8.75 = 35(d^2 - d + 0.25) + 14.15d\\8.75 = 35d^2 - 35d + 8.75 + 14.15d\\35d^2 = 20.85d\\d = 0.6 m\)

The distance moved by the mass when it is connected to the spring is 0.6 m

3) The spring potential is converted to increased PE and work within the system.

mgh = Fd + 0.5kx²...........(1)

d = x , h = dsinθ

kinetic friction force , F = μmgcosθ

mgdsinθ + μmg(cosθ)d = 0.5kd²

mgsinθ + μmgcosθ = 0.5kd

sinθ + μcosθ = kd/(2mg)

\(\mu = \frac{\frac{kd}{2mg} - sin\theta}{cos\theta} \\\\\mu = \frac{\frac{70*0.5}{2*2.2*9.8} - sin41}{cos41} \\\\\mu = 0.206\)

Answer:

A) l = 0.619m

B) l = 0.596m

C) μ = 0.314

Explanation:

The data given is:

k = 70 N/m

x = 0.5 m

m = 2.2 kg

θ = 41°

(FIGURES FOR EACH PART ARE ATTACHED AT THE BOTTOM. CONSULT THEM FOR BETTER UNDERSTANDING)

Gain in Gravitational Potential Energy = Loss in Elastic Potential Energy

mgh = (1/2)kx²

(2.2)(9.8)h = (1/2)(70)(0.5)²

h = 0.406 m

sinθ = h/l

l = h / sinθ

l = 0.406/sin41

l = 0.619m

Loss in Elastic Potential Energy in compressed spring = Gain in Gravitational Potential Energy + Gain in Elastic Potential Energy in stretched spring

(1/2)kx² = mgh + (1/2)k(l - 0.5)²

(1/2)(70)(0.5)² = (2.2)(9.8)(l·sin41)) + (1/2)(70)(l² - l + 1/4)

8.75 = 14.15(l) + 35(l²) - 35(l) + 8.75

35(l²) -20.85(l) = 0

l = 0.596m

Loss in Elastic Potential Energy = Gain in Gravitational Potential Energy + Work done against friction

(1/2)kx² = mgh + Fd

(1/2)kx² = mg(dsinθ) + μRd

(1/2)kx² = mg(dsinθ) + μ(mg · cosθ)d

(1/2)kx² = mgd (sinθ + μ(cosθ))

(1/2)(70)(0.5)² = (2)(9.8)(0.5) (sin41 + μcos41)

8.75 = 6.43 + 7.4μ

μ = 0.314

The pressure field created by faster air movement over an airfoil is; A:  higher

When the air hits the front of the wing, the air will flow in a steeper curve upward, than the bottom wing flow which will lead to the creation of a vacuum on top of the wing that pulls more air towards the top of the wing.

Finally, this air above does the same thing but it will move faster as a result of the vacuum pulling it in, and as such the vacuum now lifts the wing. Thus, Faster air movement over an airfoil creates a higher pressure field.

True, a composite material is a combination of physically distinct phases that result in aggregate properties distinct from its individual constituents.

True. A composite material is indeed a material system that consists of two or more physically distinct phases. These phases, known as constituents, can be different types of materials such as polymers, metals, ceramics, or their combinations.

The constituents are carefully selected and combined in such a way that their collective properties create new or enhanced properties in the composite material that are different from those of its individual constituents.

The behavior and properties of composite materials are determined by the interaction between the constituent phases, their arrangement, and the distribution of each phase within the material. By combining different materials, composites can exhibit desirable characteristics such as high strength, stiffness, toughness, or resistance to specific environmental conditions.

The properties of composites can be tailored by adjusting the type, proportion, and orientation of the constituents, allowing for a wide range of applications in various industries including aerospace, automotive, construction, and sports.

In summary, composite materials derive their unique properties from the synergistic effects of their constituent phases, making them versatile and widely utilized in engineering and manufacturing.

Unit test

Explanation:

Defintion: A test of each individual component (often a program) to ensure that it is as defect-free as possible.

The code only saves the first uppercase letter encountered because the index increment (j++) is placed outside the if condition, causing subsequent letters to overwrite the previous ones in the acronym array.

The issue in the given code is that the index `j` is incremented for each iteration of the loop, which causes subsequent letters to overwrite the previous letters in the `userAcronym` array.'

To resolve this issue, the increment of `j` should only occur when an uppercase letter is encountered. By moving the `j++` statement inside the `if` condition, the code will correctly save only the uppercase letters to the `userAcronym` array without overwriting them.

void CreateAcronym(char userPhrase[], char userAcronym[]) {

   int i;

   int j = 0;

   for (i = 0; i < strlen(userPhrase); ++i) {

       if (isupper(userPhrase[i])) {

           userAcronym[j] = userPhrase[i];

           j++;

       }

   }

   printf("%s", userAcronym);

}
