Answer:

 So its area A = 4 * 4sqrt(2) = 16sqrt(2) inches^2

Explanation:

In order to find the area of the section, we need to find the length of one of the diagonals.

Using the Pythagorean Theorem, a^2 + b^2 = c^2, we pick any side of the cube which in

itself is a square with sides 4 inches each.  The length of the diagonal of the square is

2(4^2) = c^2  or c = 4sqrt(2).

To calculate the area of the section, we must first determine the length of one of the diagonals. Using the Pythagorean Theorem, \(\bold{a^2 + b^2 = c^2}\), one selects any side of the cube which in its a square with four-inch sides.

           \(\to 2(4^2) = c^2 \\\\ \to c = 4\sqrt{(2)}\)

      \(\to A = 4 \times 4\sqrt{(2)} = 16\sqrt{(2)}\ inches^2\)

Therefore, the answer is "\(\bold{ 16\sqrt{(2)}\ inches^2}\)".

The steady state temperature of asphalt will be  75.32°C .

Given,

Solar radiation is absorbed on the asphalt at a rate of 625 w/m² .

Convection heat transfer coefficient is 6 w/m²-k .

Emissivity of the asphalt is 0.8.

Thermal conductivity of 0.062 w/m-k.

Asphalt is 2 inches thick

2 inches = 0.0508m

Surrounding temperature = 30°C = 86°F = 303 k

Asphalt temperature = 18.9°C = 292 k

Now,

Heat absorbed by asphalt = Heat lost by asphalt due to conduction , convection , radiation .

Let temperature of surface of asphalt be Ta

Q(conduction) = Ta - Tg/L/K(A)

Q(convection) = Ha(Ta - Tg)

Q(radiation) = ∈σ(\(Ta^4\) - \(Tg^4\))

Now substitute the values in the formula,

Q(radiation) = 0.8 * 5.67 * \(10^{-8}\)(\(303^4\) - \(Ta^4\)) W/m²

Q(Total) = Q(radiation) + Q(convection)  + Q(conduction)

625 =  0.8 * 5.67 * \(10^{-8}\)(\(303^4\) - \(Ta^4\)) + 6(303 - Ta) + Ta - 292/0.819355

Q(conduction) = Ta - 292/0.0508/0.062

Q(conduction) = 1.225(Ta - 292) W/m²

Q(convection)  =  6(303 - Ta)

Now solving for Ta,

\(4.536 * 10^{-8} Ta^4\) + 7.2205Ta = 3181.712483

Ta = 348.25 K

Ta= 167.18 °F

Ta = 75.32°C

If we reject the null hypothesis when it is actually false, we have committed a Type I error. This is also known as a false positive error. A Type I error occurs when we reject the null hypothesis, even though it is actually true. In other words, we conclude that there is a significant difference or effect when in reality there is none.

This type of error is common in hypothesis testing and can occur when the level of significance (alpha) is set too high. It is important to control for Type I errors, as they can lead to incorrect conclusions and false interpretations of the data. One way to reduce the likelihood of Type I errors is to lower the level of significance to a more conservative value, such as 0.01.

In summary, a Type I error occurs when we reject the null hypothesis when it is actually true. It is important to control for this error to ensure that our conclusions are accurate and reliable.

A runway identified as runway 27 serves operations oriented to the westward direction.

What are runways?

A runway is defined as an airport's paved surface. A runway is used for aircraft takeoff and landing operations. The most important runway, without a doubt, is the primary runway, which is the longest runway that has lighting and instrument landing aids. Runways are usually numbered based on their compass bearings, and they are designated L or R if two runways are close together but not parallel. It's worth noting that the numbers don't signify the degree to which the runway is off of a north-south heading, but rather the runway's magnetic bearing.  

How to identify the approximate direction of operations from the runway designation?

A runway identified as runway 27 serves operations oriented to the westward direction. The runway numbering system is used to determine the runway direction, which is based on its magnetic direction from 0 to 359 degrees. These numbers are used to designate runway headings in tens, as well as for headings within ten degrees. Runway 27 would be the one with the magnetic heading of approximately 270 degrees (270-279). As a result, an aircraft taking off or landing on runway 27 would travel in an approximately westward direction.

The velocity at section is approximately 42.2 m/s

Explanation:

For the water flowing through the pipe, we have;

The pressure at section (1), P₁ = 300 kPa

The pressure at section (2), P₂ = 100 kPa

The diameter at section (1), D₁ = 0.1 m

The height of section (1) above section (2), D₂ = 50 m

The velocity at section (1), v₁ = 20 m/s

Let 'v₂' represent the velocity at section (2)

According to Bernoulli's equation, we have;

\(z_1 + \dfrac{P_1}{\rho \cdot g} + \dfrac{v^2_1}{2 \cdot g} = z_2 + \dfrac{P_2}{\rho \cdot g} + \dfrac{v^2_2}{2 \cdot g}\)

Where;

ρ = The density of water = 997 kg/m³

g = The acceleration due to gravity = 9.8 m/s²

z₁ = 50 m

z₂ = The reference = 0 m

By plugging in the values, we have;

\(50 \, m + \dfrac{300 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{(20 \, m/s)^2}{2 \times 9.8 \, m/s^2} = \dfrac{100 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)50 m + 30.704358 m + 20.4081633 m = 10.234786 m + \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

90.8777353 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

v₂² = 2 × 9.8 m/s² × 90.8777353 m

The Cost of 1 kilowatt hour of energy at the rate of $0.75 per 1.5 watt hour is $500 which is 5000 times greater than the cost of energy at $0.10 per kilowatt hour.

Battery power = Current × Voltage

Cost of 1.5 Watt-hour = $0.75

Converting Energy to Watt - hour :

1 kilowatt = 1000 watt

1 kilowatt hour = 1000 watt - hour

Hence,

Cost of 1 kilowatt - hour = 1000 watt - hour can be calculated thus :

1.5 Watt-hour = $0.75

1000 Watt-hour = c

Cross multiply :

1.5c = $0.75 × 1000

1.5c = 750

c = 750 / 1.5

c = 500

Therefore, cost of 1 kilowatt - hour of energy will be $500

Comparing the cost of Energy at $500 per Kilo-Watt hour to Cost at $0.10:

$500 / $0.10 = 5000

Therefore, the cost of energy at $500 per kilowatt hour is 5000 times greater than cost at $0.10 per kilowatt hour.

estimate the TKN (Total Kjeldahl Nitrogen) associated with your sample. To calculate the TKN, we need to determine the nitrogen content from the cell tissue and ammonia.
1. Calculate the nitrogen content from cell tissue:
- Molecular composition of cell tissue: C5H7O2N
- Molecular weight of nitrogen (N): 14 g/mol
- Molecular weight of the cell tissue compound: (12x5) + (1x7) + (16x2) + (14x1) = 60 + 7 + 32 + 14 = 113 g/mol
- Nitrogen content in cell tissue: (14/113) x 100 = 12.39%
Now, we'll convert the cell tissue concentration from mg/L to nitrogen content:
- Cell tissue concentration: 50 mg/L
- Nitrogen content from cell tissue: 50 mg/L * 0.1239 = 6.195 mg/L
2. Add the nitrogen content from ammonia:
- Ammonia concentration: 10 mg/L
- Total nitrogen content (TKN): 6.195 mg/L (from cell tissue) + 10 mg/L (from ammonia) = 16.195 mg/L

Answer:

  (a) about 166.6 mA

  (b) there is no current through the 820 Ω resistor

Explanation:

You want to know the total current in the parallel circuit that has 620 Ω, 750 Ω, and 820 Ω resistors connected to a 40 V source. You want to know the possible fault if the current is 118 mA.

Each of the resistors is connected directly to the source, so the total current supplied by the source is the sum of the currents through each of the resistors:

  40V/(620Ω) ≈ 64.52 mA

  40V/(750Ω) ≈ 53.33 mA

  40V/(820Ω) ≈ 48.78 mA

The total source current is ...

  64.52 +53.33 +48.78 = 166.63 mA

The source current is about 166.6 mA.

A source current of 118 mA is about 48.63 mA less than expected. That current is approximately the amount through the 820Ω resistor, suggesting that the 820Ω resistor is not passing any current.

The 820Ω branch of the circuit appears to be "open."

A)Total Resistance = 1/((1/620)+(1/750)+(1/820)) = 468 ohms,Total Source Current = 40 V / 468 ohms = 85.51 mA (b) If the measured current was 118 mA, then this indicates that there is a fault in the circuit.

What is the measured ?

The measured is the amount or quantity of something that has been determined by careful examination or calculation. It is usually expressed as a number or a comparison. Measuring is the process of determining the amount or quantity of something, typically by comparison with a standard or unit. Measuring can be done in many ways, including the use of instruments such as rulers, scales, thermometers, and other devices.This could be due to an additional resistance in the circuit that is causing the current to increase.
