What is the smallest conductor that can be used to parallel feed a 277/480 V 60 HZ panel?

Answer:

The answer is "\(\bold{e^{-t} \sin t}\)"

Explanation:

Given equation:

\(\to x+2x+2x=0.............(a)\)

Let x= e^{mt} be a solution of the equation will be:

\(\to m^2+2m+2=0\)

compare the value with the  \(am^2+bm+c=0\)

\(\to a= 1\\\to b= -2\\\to c= 2\\\)

Formula:

\(\bold{=\frac{-b \pm \sqrt{b^2-4ac}}{2a}}\\\\=\frac{-2 \pm \sqrt{(-2)^2-4\times 1 \times 2}}{2 \times 1}\\\\=\frac{-2 \pm \sqrt{4-8}}{2}\\\\=\frac{-2 \pm \sqrt{-4}}{2}\\\\=\frac{-2 \pm 2i}{2}\\\\\)

Calculate the g.s at equation (a):

\(\to x = e^{-t} (c_1 \cos t+ c_2 \sin t)............(b)\\\\\to x = e^{-t} (c_2 \cos t -c_1 \sin t) - e^{-t} (c_1 \cos t + c_2\sin t) ...............(c)\\\\\)

\(_{when} \\\\\to t= 0\\\\\to x=x_0\\\\\to x= v_0 =1 \\\\ \ then \ form \ equation \ (b) \ and \ equation \ (c)\)

\(\to a= 0 \\ \to c_2 -c_1 =1 \\ \to c_2=1\)

The value of \(x = e^{-t} ( 0 \times \cos t + 1 \times \sin t)\)

\(\boxed{\bold{x = e^{-t} (\sin t)}}\)

We can see here that the maximum value of rolling resistance over which a loaded scraper can maintain is: 780 lb/ton

Rolling resistance is the force that resists the motion of a rolling object on a surface. Maximum rolling resistance refers to the highest level of resistance that an object can encounter while rolling on a particular surface.

For a fully loaded condition:

The total resistance = (gross + rolling) resistance

52% = 0% - rolling resistance

rolling resistance = 52%

The maximum rolling resistance = rolling resistance percentage × speed

The maximum rolling resistance = 52% (15 lb/ton)/(1% resistance)

The maximum rolling resistance = 780 lb/ton

When a neuron sends a signal, they create electrical events called actions potentials and chemical neurotransmitters.

Basically, a neuron is a fundamental units of the brain and nervous system. They are nerve cells responsible for: receiving sensory input from the external world, sending motor commands to the muscles, and for transforming and relaying electrical signals.

Being that neurons also communicates, they do so using electricals and chemicals means. So one neuron can communicate to the other via electrical events which are action potentials and chemical neurotransmitters.

An action potential causes one neuron to release chemical neurotransmitter which will help or hinder the other neuron from firing its own action potential.

In summary, neurons are essentially electrical devices having action potentials and chemical neurotransmitters as the fundamental units of sending signals or communicating with other neurons.

Arithmetic progression, geometric progression, and harmonic progression are the three categories into which number sequences are categorised in mathematics.

While geometric and arithmetic progressions share a common difference, harmonic progression is simply the inverse of arithmetic progression. The arithmetic sequence begins with a term of five and ends with a term of three. So, 3-5 = -2 is the usual difference. These numbers are used in the derived arithmetic progression formulas. Of these formulas, one is An = A1 + (n-1) (n-1). An is the nth term in the series, and in this case, The sequence's initial term is A1, its total number of terms is n, and its common difference is D. A1 = 5 and d = 2 in this issue. replacing in the equation, An = 5 + (-2)(n-1) (n-1). An should be greater than 1, and is equal to 5 - 2(n-1).

Answer:

Explanation:

I think not sure hehe

A) The air speed at which the mode test should be run is; 400 km/hr

B) The predicted drag on the prototype dish is; 170 N

We are given;

diameter of satellite dish = 2m

Wind speed; Y = 80 km/hr

Diameter of model dish = 0.4 m

Reynolds number is essential for this, thus, the formula is;

Vm * Dm/vm = VD/v

where;

D is the diameter of the dish

Vm = (vm/v) (D/Dm) Y

If vm/v = 1, then

Vm = (2/0.4) * 80

Vm = 400 km/hr

B) The formula to find the drag on the prototype dish with all similarity conditions satisfied is;

F_p = (Fm/Vm² * Dm²) * Vp² * Dp²

Thus, plugging in the relevant values gives;

F_p = (170/(400² * 0.4²)) * 2² * 80²

F_p = 170 N

The skin surface temperature is 307.2 K and the  rate of heat loss is 146 W.

The skin surface temperature may be obtained by performing an energy balance at the skin surface to give the formula;

k(T_i - T_s)/L = h(T_s - T_∞) + h_r(T⁴_s - T⁴_surr)

Now, T_surround = T_s and so making T_s the subject gives us;

T_s = [(k*T_i)/L + (h + h_r)T_∞]/((k/l)

Using the equation h_r = εσ(T_s + T_surr)(T²_s + T²_surr) we can find h_r with a guessed value of T_s = 305 K and T∞ = 297 K, to yield h_r = 5.9 W/m².K.

Then, substituting numerical values into the T_s equation, we have;

T_s = [(0.3 * 308)/(3 * 10⁻³) + (2 + 5.9)297]/[((0.3 * 308)/(3 * 10⁻³)) + (2 + 5.9)]

T_s = 307.2 K

Thus the skin temperature is 307.2 K.

The rate of heat loss can be found by evaluating the conduction through the skin/fat layer:

q_s = kA(T_i - T_s)/L

q_s = 0.3*1.8(308 - 307.2)/(3 * 10⁻³)

q_s = 146 W

The result of this SQL statement would be 6.5

Here is the breakdown of the calculation:

3 * 2 = 6

2 / 4 = 0.5

6 + 0.5 = 6.5

Define the term SQL.

SQL stands for Structured Query Language. It is a programming language used to manage and manipulate relational databases. SQL is used to communicate with a database, allowing users to create, read, update, and delete data from a database. SQL is widely used by software developers, database administrators, data analysts, and other professionals who work with data.

SQL consists of a set of commands that are used to interact with a database. These commands include SELECT, INSERT, UPDATE, DELETE, and others. SQL commands are used to retrieve data from a database, add new data, modify existing data, and delete data. SQL is used to create and manage database schemas, which define the structure of a database and the relationships between different tables.

The SQL statement SELECT 3 * 2 + 2 / 4 FROM DUAL; will produce a result of 6.5.

The statement is performing a simple arithmetic calculation, which involves multiplication, division, and addition. Here is the calculation part:

3 * 2 is calculated first, which gives us 6.

2 / 4 is calculated next, which gives us 0.5.

Finally, the results of step 1 and step 2 are added together, giving us the final result of 6.5.

Therefore, The keyword "FROM DUAL" is often used in Oracle databases to select a constant value. In this case, it doesn't have any impact on the calculation itself, as we're only performing a simple arithmetic operation.

Answer: C

Both A and B are correct

Explanation:

Latent heat is the hidden heat.

Latent heat is the heat energy required to change one state of matter to another state of matter without change in temperature. For example, solid state to liquid state, or liquid state to gaseous state.

Thermometer can not detect the latent heat. That is why it is called hidden heat.

If Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. And Technician B says that latent heat is hidden heat that is required for a change of state of matter, then we can therefore conclude that both Technician A and Technician B are correct.

Answer:

The fundamental difference between effective and less effective matrix organizations is whether the tension between different perspectives is creative or destructive. While various processes, systems and tools can help, what matters most is what top leadership says and does and how that flows through the organization in shared targets, clear accountabilities, live team interactions and team-building transparency and behaviors.

Getting matrix management right is linked inextricably to an organization’s culture - the only sustainable competitive advantage. Key components of a culture can be grouped into behaviors, relationships, attitudes, values and the environment.

Environment and values: Each organization has its own environment, context and bedrock values. Everyone needs to know what matters and why. Don’t try to do anything else until you’ve got that set.

Attitude is about choices: An organization’s overall strategy drives choices about which of its parts will be best in class (superior), world class (parity), strong (above average), or simplified/outsourced to be good enough. These choices help determine the need for a matrix and how best to design it.

Relationships and behaviors: This is why organizations have matrices. The most effective of them best balance focus and collaboration. They allow leaders and teams to build differential strengths and then work together to make the best possible decisions and scale enterprises with a creative tension that they could not do on their own.

My colleague Joe Durrett has worked all sides of matrix organizations in marketing at Procter & Gamble, sales and general management at Kraft General Foods and CEO of Information Resources, Broderbund Software and Advo. He has seen matrices at their best and at their worst and offered his perspective for this article along with his partners John Lawler and Linda Hlavac.

The scale that is based on the tenths and hundredths of an inch is c. Decimal.

The decimal scale is a measurement system that is based on tenths and hundredths of an inch. It is a precise measurement system commonly used in various fields such as engineering, manufacturing, and construction.

In the decimal scale, one inch is divided into 10 equal parts, with each part being referred to as a "tenth". Each tenth is further divided into 10 equal parts, resulting in 100 equal parts, with each part being referred to as a "hundredth". Therefore, one inch is equal to 10 tenths or 100 hundredths.

For example, a measurement of 2.45 inches would mean 2 whole inches and 45 hundredths of an inch. This can be represented as 2.45 on the decimal scale. The decimal scale is used for precision measurements where accuracy is important, and it is commonly used in applications such as machining, metrology, and inspection.

The total CPU time spent running a program can be calculated by multiplying the number of instructions by the clock cycles per instruction and the duration of each clock cycle.

In this case, a program consisting of 13,586 instructions, where each instruction takes 23 clock cycles, and each clock cycle lasts 1 nanosecond (ns). The result will provide the total CPU time in nanoseconds. To calculate the CPU time, we multiply the number of instructions by the clock cycles per instruction and the duration of each clock cycle. In this scenario, we have 13,586 instructions, each taking 23 clock cycles per instruction, and each clock cycle lasting 1 nanosecond (10^(-9) seconds). The formula to calculate CPU time is: CPU time = Number of instructions * Clock cycles per instruction * Clock cycle duration. Substituting the given values into the formula, we have: CPU time = 13,586 * 23 * 1 ns. Evaluating this expression, we find that the total CPU time spent running the program is the product of these values, resulting in the answer in nanoseconds.
