The symmetrical load below is connected to a three-phase network. A line current of 25A has been measured. The load resistors have a value of 18 Ω.
What is the line voltage of the three-phase network?
Answer:
The line voltage of the three phase network is 346.41 V
Explanation:
Star Connected Load
Resistance, R₁ = R₂ = R₃ = 18 Ω
For a star connected load, the line current = the phase current, that is we have
[tex]I_L = 25 \, A = I_{Ph}[/tex]
Whereby the the voltage across each resistance = [tex]V_R[/tex] is given by the relation;
[tex]V_R[/tex] = [tex]I_{Ph}[/tex] × R
Hence;
[tex]V_{Ph}[/tex] = [tex]V_R[/tex] = [tex]I_{Ph}[/tex] × R = 25 × 8 = 200 V
Therefore we have;
The line voltage, [tex]V_{L}[/tex] = √3 × [tex]V_{Ph}[/tex] = √3 × 200 = 346.41 V.
Hence, the line voltage of the three phase network = 346.41 V.
On single-lane roads, _____ before taking a blind curve. A. flash your headlights B. check your rearview mirror C. honk for ten seconds D. slow down to a speed that allows you to see as much as possible
Answer:
A
Explanation:
to notify an incoming vehicle or pedestrian
On single-lane roads : ( D ) slow down to a speed that allows you to see as much as possible________ before taking a blind curve
What is a single lane road ?A single lane road is a road which has traffic moving in both directions on the same lane
On a single-lane road, vehicles moving in both directions make use of a single lane, therefore when in a blind curve you should slow down to a speed that will allow you to see as much as possible an oncoming vehicle.
Hence we can conclude that On single-lane roads : ( D ) slow down to a speed that allows you to see as much as possible before taking a blind curve.

Question:
John read the first 114 pages of a novel, which was 3 pages less than ⅓ of the novel. Write an equation to determine the total number of pages (P)
Answer:
114 = ⅓P - 3
Explanation:
Given
Number of pages read = 114
Total pages in novel = p
The relationship between the pages read by John and the total pages is analysed as follows:
3 less than ⅓ of total pages means:
⅓ of total pages - 3
Recall that P represents the total pages in the novel
So, the expression becomes
⅓ * P - 3
⅓P - 3
This means that the pages read by John is ⅓P - 3
This implies that the equation to determine the number of pages in the novel is
⅓P - 3 = 114
Solving further to get the actual number of pages;
Multiply both sides by 3
3(⅓P - 3) = 114 * 3
3 * ⅓P - 3 * 3 = 114 * 3
P - 9 = 342
Add 9 to both sides
P - 9 + 9 = 342 + 9
P = 351
Hence the number of pages is 351
Answer:
Answers below
Explanation:
1. 114 = 1/3p - 3
2. 351 pages
Give five general principles involved in the process of sewage filtration?
Answer:
Some general principles are given below in the explanation segment.
Explanation:
Sewage treatment seems to be a method to extract pollutants from untreated sewage, consisting primarily of domestic sewage including some solid wastes.
The principles are given below:
Unless the components throughout the flow stream become greater than the ports or even the gaps throughout the filter layer, those holes would be filled as either a result of economic detection.The much more common element of filtration would be the use of gravity to extract a combination.Broadcast interception or interference. Inertial influence.Sieving seems to be an excellent method to distinguish particulates.1.

F=50\ hZ
R=30\ ohms
For inductance
[tex]X_L=2\times \pi\times f \times LX_L\\=2\times \pi \times 50\times 200\times 10^{-3}\\=62.8\ ohm[/tex]

2. Determining what materials can be used to make the
tacos.
3.Once the taco types are determined, making enough of them for everyone.
4.Making a few tacos and eating them to see how they taste.
Answer:
4. Making a few tacos and eating them to see how they taste.
Explanation:
The method of engineering design refers to the sequence of procedures that engineers undertake to reach a solution to a concerning problem. Generally, the solution needs to create a machine or a product that fulfills specific requirements or performs a specific function. the step of testing and redesigning includes engineers to test their final design so that they can make change their solution to enhance it, based on their feedback and their experience with the solution. As per the question eating tacos will provide the appropriate feedback to make final changes to the tacos.

What’s a pigtail when wiring
Answer:
A pigtail when wiring is technique that is used in connecting a lot of wires together.
Explanation:
A pigtail is a wire that is short in length. It has two ends. One end has a connector while the other end has other wires connected to it.
Pigtail when wiring is the connection of more than one wire in a circuit to another device. Pigtail when wiring helps to extend the length of the wire in a circuit if the wire used it short).
Pigtail when wiring is a technique what helps to keep the circuit organised because it prevents the wires from getting tangled.

Explanation:
The Hernandez family budget is shown in the graph.
A circle graph titled Family Budget. Housing is 23 percent, Food is 21 percent, Savings is 10 percent, Transportation is 16 percent, medical is 12 percent, clothing is 13 percent, emergency fund is 5 percent.
Which 3 categories make up more than half of the Hernandez family budget? Select two choices..
clothing, medical, and emergency fund
clothing, housing, and savings
housing, savings, and food
housing, food, and transportation
food, transportation, and emergency fund
Answer:
housing, savings, and food
housing, food, and transportation
Explanation:
Given: Family Budget comprises of 23% housing, 21% food, 10% savings, 16% transportation, 12% medical, 13% clothing and 5% emergency fund.
To find: categories that make up more than half of the Hernandez family budget
Solution:
clothing + medical + emergency fund = [tex]13+12+5=30 \%[/tex]
clothing + housing + savings = [tex]13+23+10=46\%[/tex]
housing + savings + food = [tex]23+10+21=54\%[/tex]
housing + food + transportation = [tex]23+21+16=60\%[/tex]
food + transportation + emergency fund = [tex]21+16+5=42\%[/tex]
So, 3 categories that make up more than half of the Hernandez family budget are housing, savings, and food, housing, food, and transportation
