Answer: a heathen

Explanation:

The term for a person who does not share the belief of the dominant religion of a society is "a heathen". The correct option is A.

A society is a group of people who interact with one another on a regular basis, or a large social group that shares the same spatial or social territory and is typically subject to the same political authority and dominant cultural expectations.

"A heathen" is a person who does not share the beliefs of a society's dominant religion.

The term is frequently used to describe someone who is considered uncivilized or primitive because of their religious beliefs, especially in societies where the dominant religion wields significant power and influence.

However, it is important to note that the term can be considered derogatory and offensive, and it is generally more respectful to refer to people of different religious beliefs using neutral or positive terms.

Thus, the correct option is A.

Thus, the secondary voltage is 77,000 volts and the secondary current is 0.213 amps.

The secondary voltage and current can be determined using the transformer equation, which states that the ratio of the number of turns on the primary winding to the number of turns on the secondary winding is equal to the ratio of the primary voltage to the secondary voltage. In other words:

Primary turns / Secondary turns = Primary voltage / Secondary voltage

In this case, we know that the transformer has 100 primary turns and 35,000 secondary turns, and is supplied by 220 volts and 75 amps. We can rearrange the transformer equation to solve for the secondary voltage:

Secondary voltage = Primary voltage x (Secondary turns / Primary turns)

Secondary voltage = 220 volts x (35,000 / 100)

Secondary voltage = 77,000 volts

Therefore, the secondary voltage is 77,000 volts.

To determine the secondary current, we can use the equation for power:

Power = Voltage x Current

Since the power is the same on both sides of the transformer, we can write:

Primary voltage x Primary current = Secondary voltage x Secondary current

Substituting the known values, we get:

220 volts x 75 amps = 77,000 volts x Secondary current

Solving for the secondary current, we get:

Secondary current = (220 volts x 75 amps) / 77,000 volts

Secondary current = 0.213 amps

Therefore, the secondary current is 0.213 amps.

In summary, the secondary voltage is 77,000 volts and the secondary current is 0.213 amps.

Explanation:

Answer:

20368.917N

Explanation:

Frictional force (F) is the product of the Coefficient of friction and the normal reaction.

F = μN

Coefficient of friction, μ = 0.2

Normal reaction = MgCosθ

Mass, m = 12 tonnes = 12 * 1000 = 12000 kg

N = 12000 * 9.8 * cos30

N = 101844.58

F = 0.2 * 101844.58

F = 20368.917N

Explanation:

Since the rollers are identical and the surfaces are smooth, the reaction forces at points A and C must be equal and vertical.

Let's call this force R. At point B, the reaction force is perpendicular to the inclined plane, so we can use trigonometry to find its magnitude.

Let's call this force T. Using the forces in the vertical direction, we can write: 2R + T = 2Q Using the forces in the horizontal direction

we can write: T = R tanθ where θ is the angle of inclination of the plane. Substituting the second equation into the first, we get: 2R + R tanθ = 2Q Simplifying: R (2 + tanθ) = 2Q R = 2Q / (2 + tanθ)

Plugging in the values: R = 2(100N) / (2 + tanθ) We can use trigonometry to find the value of tanθ: tanθ = opposite / adjacent = BC / AB

Since the rollers are identical, BC = AB, so: tanθ = AB / AB = 1 Therefore, R = 2(100N) / (2 + 1) = 50N and T = R tanθ = 50N * 1 = 50N

So the reaction forces at points A and C are both equal to 50N and vertical, while the reaction force at point B is equal to 50N and perpendicular to the inclined plane.

The control limit using Sample Upper Control Limit (UCL) is determined to be 20.7 . Control limits are statistical calculations used in process control to determine the boundaries within which a process is considered to be under control.

Control limits are typically calculated based on historical data and the desired level of control for a specific process. They help identify whether the process is operating within acceptable limits or if there are variations that require investigation and corrective action. The UCL represents the upper boundary beyond which the process is considered to be out of control.

By comparing the observed values or sample measurements to the control limits, organizations can monitor and assess the performance of a process.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

A masthead light is required for non-powered vessels under 23 feet operating during times of restricted visibility.

During times of restricted visibility, it is crucial for vessels to display the appropriate navigation lights to ensure safety and avoid collisions. Non-powered vessels, which include sailboats, rowboats, and canoes, are required to adhere to specific lighting regulations. In the case of non-powered vessels under 23 feet in length, a masthead light is required during times of restricted visibility.

The masthead light is typically a white light positioned at the highest point on the vessel, such as the top of the mast. It provides a 225-degree arc of visibility from dead ahead to 22.5 degrees abaft the beam on both sides of the vessel. The purpose of the masthead light is to make the vessel more visible to other boaters, indicating its presence and direction of travel.

By displaying a masthead light, non-powered vessels under 23 feet can improve their visibility during periods of restricted visibility, such as fog, darkness, or heavy rain. This helps other vessels to identify and navigate around them, reducing the risk of accidents or collisions.

Answer:

15300 N

Explanation:

\(\rho_i\) = Density of air at inlet

\(\dfrac{m}{t}\) = Mass flow rate = 60 kg/s

\(v_i\) = Inlet velocity = 225 m/s

\(\rho_o\) = Density of gas at outlet = \(0.25\ \text{kg/m}^3\)

\(A_i\) = Inlet area

\(A_o\) = Outlet area = \(0.5\ \text{m}^2\)

Since mass flow rate is the same in the inlet and outlet we have

\(\rho_iv_iA_i=\rho_ov_oA_o\\\Rightarrow v_o=\dfrac{\dfrac{m}{t}}{\rho_oA_o}\\\Rightarrow v_o=\dfrac{60}{0.25\times 0.5}\\\Rightarrow v_o=480\ \text{m/s}\)

Thrust is given by

\(F=\dfrac{m}{t}(v_o-v_i)\\\Rightarrow F=60\times (480-225)\\\Rightarrow F=15300\ \text{N}\)

The thrust generated is 15300 N.

Students with learning disabilities who struggle with mathematics often have difficulty shifting from one task or operation to the next (option D). This difficulty is known as cognitive flexibility, and it can impede their overall understanding and application of mathematical concepts.

While they may excel in other areas such as applying money concepts (option A), having good memory skills (option C), or performing well in spatial relations (option B), these strengths do not necessarily compensate for their challenges in mathematics. Additionally, they may encounter more difficulty with basic mathematical concepts compared to word problems (option E). Students with learning disabilities and mathematics difficulties commonly face challenges in cognitive flexibility, making option D the most fitting choice. Cognitive flexibility refers to the ability to switch between different tasks, operations, or strategies while solving problems. Difficulties with cognitive flexibility can hinder students' understanding and mastery of mathematical concepts, as they may struggle to adapt their thinking and approach when faced with different types of problems. Although some students with learning disabilities may perform well in specific areas, such as applying money concepts (option A), having good memory skills (option C), or excelling in spatial relations (option B), these strengths do not necessarily translate into overall success in mathematics. While money concepts involve practical applications of mathematics, they may not require the same level of cognitive flexibility and abstract reasoning as other mathematical topics. Similarly, spatial relations involve visual-spatial skills, which can be distinct from mathematical problem-solving. Furthermore, students with learning disabilities often face more difficulty with basic mathematical concepts than with word problems (option E). Basic concepts in mathematics often require a solid understanding of foundational principles, which can be challenging for individuals with learning disabilities. In contrast, word problems may provide contextual information that aids comprehension and helps students apply their mathematical knowledge in a more practical or relatable manner.

Explanation:

The river has an average rate of water flow of 59.6 m³/s.

Tributary B accounts for 47% of the rate of water flow. Therefore the rate of water flow through tributary B is:

Flow rate of water through tributary B = 47% of 59.6 m³/s = 0.47 * 59.6 m³/s = 28.012 m³/s

The volume of water that has been discharged through tributary B = Flow rate of water through tributary B * time taken

time = 30 minutes = 30 minutes * 60 seconds / minute = 1800 seconds

The volume of water that has been discharged through tributary B in 30 seconds = 28.012 m³/s * 1800 seconds = 50421.6 m³

We estimated the number of panels for a PV based system and calculated the system cost using the given data. We found that 4000 panels would be required for this system and the system cost would be $6,300,000.

Estimation of the number of panels for PV based system:

The amount of energy required by the solar panels can be estimated using the following formula:

Energy = Power x Time Where, Energy = 126 kWh/day Power = 315 W Time = 4 hours/day

Substituting these values in the formula,

we get: Energy = 315 x 4 kWh/day Energy = 1260 kWh/day

The number of panels can be estimated using the following formula:

Number of panels = Total power required / Power of each panel Where, Power of each panel = 315 W Total power required = 1260 kWh/day x 1000 W/kW = 1260000 W Number of panels = 1260000 W / 315 W Number of panels = 4000 panels

The system cost can be calculated as follows:

Total power = 1260 kWh/day x 1000 W/kW = 1260000 W System cost = Total power x Cost per watt

Where, Cost per watt = $5 System cost = 1260000 W x $ 5/W System cost = $6,300,000
