If a rectangular area is rotated in a uniform electric field from the position where the maximum electric flux goes through it to an orientation where only half the flux goes through it, what has been the angle of rotation?

[ad_1]

Answered by answersmine AT 22/10/2019 – 02:27 AM

With a uniform electric field, flux go along parallel paths, then flux is therefore proportional to the cosine of the angle rotated.
0 degree rotation => cos(0)=1 => 100% of flux.
60 degrees rotation => cos(60) => 0.5  => how many % of flux?

A field in the shape of a right triangle has an area of 30 square meters. If one leg of the right triangle that forms the field is 4 meters longer than the other leg, what is the length of the longer leg?

[ad_1]

Let S=length of shorter leg, then the longer leg measures S+4.
Area of a right triangles = product of legs /2  (in m.)
and
Area of given right-triangle = 30 m^2

To find S, solve
product of legs /2 = S (S+4) / 2 = 30 = area of triangle
S(S+4) = 2*30      [ now distribute ]
S^2+4S = 60        [ subtract 60 from both sides ]
s^2+4S-60=0
Solve for S by factoring
(S+10)(S-6)=0    means  (S+10)=0 or (S-6)=0
Therefore S=6 or S=-10, reject negative root, so
shorter leg = 6m
longer leg = 6m+4m = 10m

Which excerpt from “The Scarlet Ibis” most foreshadows that the narrator will feel regret for something he has done to Doodle? But sometimes (like right now), as I sit in the cool, green-draped parlor, the grindstone begins to turn, and time with all its changes is ground away—and I remember Doodle. Doodle was my brother and he was going to cling to me forever, no matter what I did, so I dragged him across the burning cotton field to share with him the only beauty I knew, Old Woman Swamp. There is within me (and with sadness I have watched it in others) a knot of cruelty borne by the stream of love, much as our blood sometimes bears the seed of our destruction, and at times I was mean to Doodle. Once I had succeeded in teaching Doodle to walk, I began to believe in my own infallibility and I prepared a terrific development program for him, unknown to Mama and Daddy, of course.

Gather references, and prepare your résumé.

Explanation:

Before a job interview, it is advisable to prepare a copy of your résumé and references, as well as bring a pen and notepad.

The rest of the alternatives are incorrect because asking the company to keep your résumé on file is inappropriate – you should always carry a copy of  it; asking and answering questions politely happens during the course of the interview; and restating your interest is done after the interview has occurred.

Two point particles, one with charge +8 × 10–9 c and the other with charge–2 × 10–9 c, are separated by 4 m. the electric field midway between them is:

[ad_1]

Answer:

a) The time the police officer required to reach the motorist was 15 s.

b) The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) The total distance traveled by the officer was 225 m.

Explanation:

The equations for the position and velocity of an object moving in a straight line are as follows:

x = x0 + v0 · t + 1/2 · a · t²

v = v0 + a · t

Where:

x = position at time t

x0 = initial position

v0 = initial velocity

t = time

a = acceleration

v = velocity at time t

a)When the officer reaches the motorist, the position of the motorist is the same as the position of the officer:

x motorist = x officer

Using the equation for the position:

x motirist = x0 + v · t (since a = 0).

x officer = x0 + v0 · t + 1/2 · a · t²

Let´s place our frame of reference at the point where the officer starts following the motorist so that x0 = 0 for both:

x motorist = x officer

x0 + v · t = x0 + v0 · t + 1/2 · a · t²      (the officer starts form rest, then, v0 = 0)

v · t = 1/2 · a · t²    

Solving for t:

2 v/a = t

t = 2 · 15.0 m/s/ 2.00 m/s² = 15 s

The time the police officer required to reach the motorist was 15 s.

b) Now, we can calculate the speed of the officer using the time calculated in a) and the  equation for velocity:

v = v0 + a · t

v = 0 m/s + 2.00 m/s² · 15 s

v = 30 m/s

The speed of the officer at the moment she overtakes the motorist is 30 m/s

c) Using the equation for the position, we can find the traveled distance in 15 s:

x = x0 + v0 · t + 1/2 · a · t²

x = 1/2 · 2.00 m/s² · (15s)² = 225 m

Jim enjoys playing basketball. he figures that he makes about 50% of the field goals he attempts during a game. in this situation, we’ll say success occurs when jim makes an attempted field goal. what is the value of p?

[ad_1]

The following equation of parabola is given:

p(x)= – 5 x^2 + 240 x – 2475

where p(x) = y

This is a standard form of the parabola. We need to
convert this into vertex form of equation. The equation must be in the form:

y – k = a (x – h)^2

Where h and k are the vertex of the parabola. Therefore,

y = – 5 x^2 + 240 x – 2475

y = -5 (x^2 – 48 x + 495)

Completing the square:

y = -5 (x^2 – 48 x + 495 + _) – (-5)* _

Where the value in the blank _ is = -b/2

Since b = -48        therefore,

y = -5 (x^2 – 48 x + 495 + 81) + 405

y – 405 = -5 (x^2 – 48 x + 576)

y – 405 = -5 (x – 24)^2

Therefore the vertex is at points (24, 405).

The company should make 24 tables per day to attain maximum

The field of ________ is concerned with maintaining biological diversity.

[ad_1]

Answer:

Helicases unwind the two parental DNA’s strands and creates the replication fork; single strand binding proteins keep the single strand from joining.


Further information:

• DNA replication: a biological method occurring in all living organisms that is the basis for biological inheritance

Helicase: It is an enzyme that may unwinds the DNA helix ahead of the replication machinery.

Origin of replication: a specific sequence in a genome at which replication is started.


Steps of DNA replication:

• During initiation, proteins fix to the source of replication while helicase unwinds the DNA helix and two replication forks are formed at the source of replication.

• During elongation, a primer sequence is added with complementary RNA nucleotides, which are then substituted by DNA nucleotides.

• During elongation the leading strand is made constantly, while the lagging strand is made in portions called Okazaki fragments.

• During termination, primers are detached and substituted with new DNA nucleotides and the backbone is stuck down by DNA ligase.

Purpose of DNA replication:

The purpose of DNA replication is to produce two duplicate copies of a DNA molecule. This is essential for cell division during development or repair of damaged tissues. DNA replication ensures that each new cell receives its own replica of the DNA.

Answer details:

Subject: Biology

Level: High school

The equation for how temperature changes the resistance R is: 

R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance. 

The resistance of the copper wire increases by 18% or by 0.18, so the new value for the resistance is R=1.18*R₀.

T₀=20°C
=0.0068
R=1.18*R₀

Now we need to input that into the equation for resistance change and solve for temperature T.  

1.18R₀=R₀(1+α(T-20)), R₀ cancels out,

1.18=1+α(T-20),

1.18-1=α(T-20), we divide by α,

0.18/α=T-20, we put 20 on the left side,

26.47+20=T

T=46.47°C

So the temperature on which the resistance of copper wire will increase by 18% is T=46.47°C.

The Reformation actually started after Columbus’s landing in North America. 

Treaty of Tordesillas in 1494 was forced on Spain and Portugal by the Pope. The Pope basically said that all lands in the New World belonged to Spain and all new non-Christian lands in the Eastern Hemisphere belong to Portugal. No other Catholic countries can do anything in those areas without the approval of the owner. 

The pope basically drew two lines on the globe setting the border. The western line started at the north pole cut half way through Greenland and ended at the south pole. The new world was everything to the west. Problem is that it ran through a chunk of Brazil which is why Brazil is an ex-Portuguese colony. 

The Eastern line starts at the North Pole runs through siberia, through the pacific just west of Japan, and cuts Australia in half. Of course, Australia hadn’t been discovered yet. Everything to the the east of this line is the new world. 

Obviously, this treaty didn’t hold up well, but the reformation gave the protestant countries an excuse to explore the new world since they didn’t have to take orders from the Pope. Even so, France, a catholic country, ignored it too. 

Really, the only country that was effected by the reformation in the exploration of the Americas was England. All the other countries, changed their religion once and then went to war with the nearest catholic country. Sweden became Lutheran and stayed that way. The Dutch Republic became Calvinists and stayed that way. 

England kept switching. First it was Catholic. Then, Henry VIII made it protestant. Then, Henry’s daughter Mary I made it catholic again. Henry’s other daughter Elizabeth I (with the two hit movies) made it Protestant again. 

Years latter, Oliver Cromwell over through the monarchy, executed the King Charles I, and established a Protestant fundamentalist religious military dictatorship. He outlawed drinking,smoking, gambling, theater, dirty books, sports, prostitution, and anything generally fun. He would have made Saudi Arabia proud. Basically, all you could do is work, pray, and die. Sex was allowed for creating children, but you couldn’t enjoy it. 

When Cromwell died, the people of England said enough was enough and brought back the King. Charles II kicked out the fundamentalists and brought back drinking, smoking, gambling, dirty books, sports, prostitution, and having fun during sex. Incidentally, those were also all his hobbies. 

This brings us to the famous Pilgrims. They were part of Cromwell’s crowd. They kept agitating a return to the no-fun policy. They annoyed everybody. They weren’t persecuted for practicing their religion, they were persecuted because they kept trying to force their religion on everyone else. Sort of like Southern Baptists. 

Charles II was the most easy going monarch in British history. Do realize how annoying you have to be to get him to throw you out. 

Charles’s brother James II was obsessed with turning Great Britain catholic again. After four years of trying, they kicked him and his followers out.

Karl Marx developed the economic theory of communism.

Further Explanation:

One of Karl Marx’s most famous contributions came in his book the Communist Manifesto. This book explained Mark’s views on government, the economy, and ultimately lead to the creation of communism as an idea.

A communism system is one that is economic and political in nature. In this system, the government would control the means of production, the distribution of goods and resources, and would overall have significant control over society. This system of communism is the opposite of the capitalist/democratic system used in America today. These two ideologies would clash during the mid 20th century in what is now known as the Cold War.

Marx’s ideas were based on his observations of the world around him. He felt that the mistreatment of labor by industry and private corporations would ultimately lead to an uprising by angry laborers all over the world.

No doubt, a rose can be a symbol of love. But there is also a lot of deeper meanings. Passion, true love, immortal love, the everlasting, and a love that will never fade. It can also symbolize sacrifice, respect, or be a memorial.

Roses can also symbolize desire, sensuality, and passion.

Roses can symbolize a tribute to loved ones, family, children, or a lost love. Sailors would get roses to symbolize a reminder of leaving behind someone they loved, or a tribute love lost along the way.

For the feminine roses can symbolize femininity, elegance, compassion, gentleness, and beauty.

A rose can symbolize falling in love and youth, and a rose with thorns can mean there is another side to love and be careful. Roses and thorns can also mean with love comes sacrifice, and there may be pain, or the pain one has experienced through love. Roses can honor our loved ones, and bring peace in turbulent times. It can also be a symbol of respect, friendship, or devotion.

A black rose can symbolize death, the dark side of living. While a red rose can symbolize faith and honor. In Christianity, a red rose symbolizes Christs death and the sacrifice he made for everlasting life.

Roses can symbolize all life: a rosebud as youth, or a wilted rose as something loss or the end of an era.

The gravitational force Fg between two objects is given by the equation:

Fg=(G*m₁*m₂)/r₂, where G=6.67*10^-11 m³ kg⁻¹ s⁻² is the gravitational constant, m₁ and m₂ are the masses of the two bodies and r is the distance between those bodies. 

Due to the gravitational attraction the pencil and the eraser will attract if we there is no friction on the surface. 

m₁=10 g=0.01 kg is the mass of the pencil
m₂=20 g=0.02 kg is the mass of the eraser
r=2.5 cm = 0.025 m

First we calculate the Fg:

Fg={(6.67*10^-11)*0.01*0.02}/(0.025²)=2.1344*10^-11 N

To get the velocity v of the pencil:

v²=2as, where a is the acceleration of the pencil and s is the path. In our case s=r so we can write:

v²=2ar

a=Fg/m₁= 2.133*10^-9 m/s²

v²=2*(2.133*10^-9)*0.025=1.0665*10^-10

v=√(1.0665*10^-10)=1.0327*10^-5 m/s

We have the velocity and the acceleration, so we can calculate the time t with the equation:

t=v/a=(1.0327*10^-5)/(2.133*10^-9)=4841.6 s

1 hour has 3600 s so when we divide time t in seconds by 3600 we get time T in hours:

T=t/3600=4841.6/3600=1.3449 h. 

So the time for the pencil and eraser to touch is T=1.3449 hours. 

Also time T can be expressed like T= 1h and 20 mins and 41.64 s

Answer:

The answer is C. In order to carefully control conditions and confirm or disconfirm a hypothesis about the causes of behavior, one must perform an experiment.

Explanation:

Experimental research allows the researcher to control all the variables in order to create the conditions that can confirm or disconfirm a hypothesis. This method aimes to establish a relation of causality between two variables, which means that one variable is generated and determined by the other; this is posible because all of the other variables that can influence it have been controlled.

When a researcher conducts a survey or engages in naturalistic observation, he can’t control the variables, therefore, he can only establish a correlation between two variables, but not of causality.

Answer:

Option C – BD=76 cm

Step-by-step explanation:

Given : You are designing a diamond-shaped kite. you know that AD = 44.8 cm, DC = 72 cm, and AC = 84.8 cm.

To find : How long BD should it be?

Solution :

First we draw a rough diagram.

The given sides were AD = 44.8 cm, DC = 72 cm and AC = 84.8 cm.

According to properties of kite

Two disjoint pairs of consecutive sides are congruent.

So, AD=AB=44.8 cm

DC=BC=72 cm

The diagonals are perpendicular.

So, AC ⊥ BD

Let O be the point where diagonal intersect let let the partition be x and y.

AC= AO+OC

AC=  x+y=84.8 …….[1]

Perpendicular bisect the diagonal BD into equal parts let it be z.

BD=BO+OD

BD=z+z

Applying Pythagorean theorem in ΔAOD

where H=AD=44.8 ,P= AO=x , B=OD=z

H^2=P^2+B^2

(44.8)^2=x^2+z^2  ………[2]

Applying Pythagorean theorem in ΔCOD

where H=DC=72 ,P= OC=y , B=OD=z

H^2=P^2+B^2

(72)^2=y^2+z^2 …………[3]

Subtract [2] and [3]

(72)^2-(44.8)^2=y^2+z^2-x^2-z^2

5184-2007.04=(x+y)(x-y)

3176.96=(84.8)(x-y)

37.464=x-y ……….[4]

Add equation [1] and [4], to get values of x and y

x+y+x-y=84.8+37.464

2x=122.264

x=61.132

Substitute x in [1]

x+y=84.8

61.132+y=84.8

y=23.668

Substitute value of x in equation [2], to get z

(44.8)^2=x^2+z^2

(44.8)^2=(23.668)^2+z^2

2007.04-560.174224=z^2

z=sqrt{1446.865776}

z=38.06

We know, BD=z+z

BD= 38.06+38.06

BD= 76.12

Nearest to whole number BD=76 cm

Therefore, Option c – BD=76 cm is correct.

Great Depression convinced a lot of people that the government had a role in

The correct answer of this question is : C i.e Gravitational < Weak nuclear force < Electromagnetic force < Strong nuclear force.

EXPLANATION:

There are four fundamental forces in nature which are known as gravitational force, weak nuclear force, electromagnetic force and strong nuclear force.

Out of these four fundamental forces, the gravitational force is the weakest forces in nature,but has infinite range.

Weak nuclear force is produced due to W/Z bosons. Hence, it is stronger than gravitational force but weaker as compared to electromagnetic and strong nuclear force. It is a short range force.

Electromagnetic force is the third one which is weaker as compared to strong nuclear force but has infinite range.

Strong nuclear force is a short range, spin dependent strong attractive force that arises between nucleons due to exchange of mesons.
