Andrei [34K]2 years ago
5 0

The watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.

Given that power factor is 0.2, input is 100V and electricity current be 4 amperes.

We are required to find the number of watts that are consumed in circuit.

An electric current is basically a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space.

Power factor is basically the ratio of working power, measured in kilowatts , to apparent power, measured in kilovolt amperes.

Number of watts that are consumed will be=100*0.2*4

=80 watts

Hence the watts that are consumed in a circuit that is having power factor of 0.2 and input is 100V at 4 ampheres is 80 watts.

Answer:

The more you use, the more you have

When you drink water (or any liquid).

Explanation:Similar for food: From a caloric standpoint, a McSupersized extra value meal should provide you with plenty of fuel to use.  But how do you feel after you eat one of those?  Unless you’re starving, less is more when it comes to food.Same for sleeping: Logging in 12-hour sessions seems like it should ready you for the day, but usually it leaves you dragging.  Unless you’re sleep deprived, it’s worth seeing what happens when you sleep just a little less.Healthy people drink a lot of water, as well they should.  But consider when you’re drinking that water: If you’re drinking it with your meal, you could be impairing your digestion.Not only does water dilute the gastric juices required to digest food, it also exits the stomach after just a few minutes, taking those juices with it and making digestion difficult.  And since digestion accounts for 5 to 15 percent of your energy expenditure, that’s something you should care about.

Artist 52 [7]

In the context of Alabama in the 1900s, the umwa was culturally and historically significant because it supported the civil rights movement in supported coal mining companies.

<h3>The umwa</h3>

The United Mine Workers of America (UMW or UMWA) is a North American labor union best known for representing coal miners. Today, the Union also represents health care workers, truck drivers, manufacturing workers and public employees in the United States and Canad.

With this information, we can conclude that in the context of Alabama in the 1900s, the umwa was culturally and historically significant because it supported the civil rights movement in supported coal mining companies.

Georgia’s scores in six subjects are 89, 75, 92, 68, 78, 75, and 80. If she finds a single value that summarizes all the values
Allushta [10]
Hey there! :)

Your answer is mean
_____________________________________________________________

Mean is the average value of the data set.
Mode is the number that appears the most
Range is the difference between the greatest value and the lowest value in a data set.

Finding the mode is pretty useless because you can't do much with the score that you got the most.

Range isn't that helpful because it's the difference between your best and worst score.

Mean is best for summarizing because you have 1 number that's the average of the whole data set.
______________________________________________________________

Therefore, the answer is mean

Hope this helps :)

What it means that [If x is a factor of p(x), what is the value of k?]
kompoz [17]

Answer:

k = -4

Explanation:

Given

P(x) = (3x^2 - 5)(x + k) - 20

x is a factor

Required

Solve for k

x is a factor means that the polynomial can be divided successfully by x.

In other words, x is a zero of the polynomial.

i.e.

x = 0 and P(x) = 0

Substitute 0 for x in P(x)

P(x) = (3x^2 - 5)(x + k) - 20

P(x) = (3*0^2 - 5)(0 + k) - 20

P(x) = (0- 5)(k) - 20

P(x) = (-5)(k) - 20

P(x) = -5k - 20

Substitute 0 for P(x)

0 = -5k - 20

Collect Like Terms

5k = - 20

Divide both sides by 5

k = -4

Lesson 6 homework practice use the pythagorean theorem answer key
labwork [276]

Pythagorean theorem should be used to determine the length of any of the three sides of a right-angled triangle.

<h3>What is Pythagorean Theorem?</h3>

Pythagorean theorem can be defined as a fundamental mathematical equation in Euclidean geometry and it can be used to determine the length of any of the three (3) sides of a right-angled triangle.

Mathematically, Pythagorean's Theorem is given by this formula:

c² = a² + b²

<u>Where:</u>

  • c is the hypotenuse.
  • a is the adjacent side.
  • b is the opposite side.

<u>For example:</u>

c² = 3² + 4²

c² = 9 + 16

c² = 25

c = √25

c = 5 units.
