The correct order of decreasing size for sedimentary grain sizes is D) gravel, sand, silt, and clay.

Grain size is an important characteristic of sedimentary rocks, and it affects their appearance, texture, and properties. Sedimentary grains can range from very small (clay-sized particles) to very large (gravel-sized particles). The order of decreasing grain size is determined by the settling velocity of each grain size in water. Gravel-sized particles settle the fastest, followed by sand, silt, and clay. Therefore, sedimentary rocks that are composed of larger grains (like gravel) are typically deposited in high-energy environments, such as near rivers, while sedimentary rocks with smaller grains (like clay) are typically deposited in low-energy environments, such as deep ocean basins.

Answer:

The diameter of the contact area between the ball and the floor is approximately 28 milimeters.

Explanation:

The basketball experiments a normal stress (\(\sigma\)), in pascals, due to normal force from the floor (\(N\)). By definition of normal stress, we have the following equation:

\(\sigma = \frac{4\cdot N}{\pi\cdot D^{2}}\) (1)

Where \(D\) is the diameter of the contact area between the ball and the floor, in meters.

Please notice that magnitude of the normal force equals the magnitude of external force given by the basketball player and weight is negligible in comparison with normal and external forces.

If we know that \(N = 50\,N\) and \(\sigma = 8.0\times 10^{4}\,Pa\), then the diameter of the contact area is:

\(\sigma = \frac{4\cdot N}{\pi\cdot D^{2}}\)

\(D^{2} = \frac{4\cdot N}{\pi\cdot \sigma}\)

\(D = 2\cdot \sqrt{\frac{N}{\pi\cdot \sigma} }\)

\(D = 2\cdot \sqrt{\frac{50\,N}{\pi\cdot (8\times 10^{4}\,Pa)} }\)

\(D\approx 0.028\,m\) \((28\,mm)\)

The diameter of the contact area between the ball and the floor is approximately 28 milimeters.

Deep foundations are used when the surface soils are not capable of supporting the loads of a structure. Two common types of deep foundations are replacement and displacement foundations.

1. Replacement foundations:

Replacement foundations are created by removing the soil beneath a structure and replacing it with concrete or other materials. This creates a solid, stable foundation that can support the weight of the structure.

Illustration: The process of creating a replacement foundation begins by excavating the soil beneath the structure, leaving a large hole. The hole is then filled with concrete, which is allowed to cure and harden. The concrete provides a solid base for the structure to rest on, ensuring that it is stable and secure.

2. Displacement foundations:

Displacement foundations work by pushing soil aside as they are installed, creating a cavity in the ground that is then filled with concrete. These foundations are often used when soil conditions are too difficult to excavate or when a more efficient installation method is desired.

Illustration: The process of creating a displacement foundation involves driving a steel pile or tube into the ground. The pile is typically filled with concrete as it is being driven, creating a cavity in the soil. Once the pile has reached the desired depth, it is left in place, and the cavity is filled with concrete. This creates a solid, stable foundation that can support the weight of the structure.

In summary, both replacement and displacement deep foundations are effective methods for creating stable foundations for structures when the soil conditions are not suitable for shallow foundations. The choice of foundation type depends on the specific site conditions, load requirements, and project budget.

The voltages V1 and V2 in the given circuit are 2.5V and 10V, respectively.

Kirchhoff's Current Law (KCL) is a fundamental law in electrical engineering that governs the flow of current. The KCL explains that the current that enters a node is equal to the sum of the current leaving the node. We can use KCL to calculate voltages in a circuit that has several branches or junctions. In this circuit, the current entering the node is equal to the sum of the current leaving the node. V1 is found using KCL. The sum of currents at the junction of V1 is given by:$$I_{1}+I_{2}=I_{3}$$

Where;

\($$I_{1}=\frac{V_{1}}{4}$$$$I_{2}=\frac{V_{1}}{12}+\frac{V_{1}}{6}=\frac{3V_{1}}{12}+\frac{2V_{1}}{12}=\frac{5V_{1}}{12}$$$$I_{3}=\frac{20-V_{1}}{8}\)

\($$Substituting these values in the above equation we get:$$\frac{V_{1}}{4}+\frac{5V_{1}}{12}=\frac{20-V_{1}}{8}$$$$3V_{1}+5V_{1}=30-4V_{1}$$\)

\($$12V_{1}=30$$$$V_{1}=\frac{30}{12}$$$$V_{1}=2.5V$$Similarly, we can find V2 using KCL:$$I_{4}+I_{3}=I_{5}$$$$I_{4}=\frac{V_{2}}{4}$$$$I_{5}=\frac{20-V_{2}}{8}+\frac{20-V_{2}}{6}$$$$I_{5}=\frac{4(20-V_{2})+3(20-V_{2})}{24}$$\)

\($$I_{5}=\frac{140-7V_{2}}{24}$$Substituting these values in the above equation we get:$$\frac{V_{2}}{4}+\frac{20-V_{1}}{8}+\frac{20-V_{2}}{6}=\frac{140-7V_{2}}{24}$$$$6V_{2}+3(20-V_{2})+4(20-V_{1})=140-7V_{2}$$$$6V_{2}+60-3V_{2}+80-4(2.5)=140-7V_{2}$$$$3V_{2}=30$$$$V_{2}=10V$$\)

A type of sorting algorithms known as external sorting is capable of processing enormous volumes of data.

When the data that has to be sorted cannot fit in a computer's primary memory (often RAM) and must instead be stored in a slower external memory, typically a disk drive, external sorting is necessary.

Although the array has already been sorted, our algorithm does not know whether it has finished. To know it is sorted, the algorithm needs to complete one full pass without any swaps.

The refrigerant-134a will be at a temperature of 9.81°C and have a specific entropy of 0.5122 kJ/kg·K at a pressure of 160 kPa.

To determine the properties of refrigerant-134a when throttled from a saturated liquid state at 700 kPa to a pressure of 160 kPa, we can use the refrigerant tables for R-134a.

1. Saturated Liquid State at 700 kPa:

Using the refrigerant tables, we can find the properties of refrigerant-134a at 700 kPa:

- Temperature (T1) = 24.97°C

- Specific enthalpy (h1) = 163.47 kJ/kg

- Specific entropy (s1) = 0.6146 kJ/kg·K

2. Throttling to 160 kPa:

Since the refrigerant is throttled, the process is considered isenthalpic (constant enthalpy). Therefore, the specific enthalpy data remains the same after throttling:

- Specific enthalpy (h2) = h1 = 163.47 kJ/kg

To find the properties at the final pressure of 160 kPa, we need to look up the properties at this pressure in the refrigerant tables.

- Temperature (T2) = 9.81°C

- Specific entropy (s2) = 0.5122 kJ/kg·K

So, after throttling, the refrigerant-134a will be at a temperature of 9.81°C and have a specific entropy of 0.5122 kJ/kg·K at a pressure of 160 kPa.
