Diameter is 7/22 cm. What is the circumference?

We are given a diameter of 7/22 centimeters.

A diameter is the length of a straight line segment which passes through the center of a circle and has its endpoints on the circle itself.

The circumference of a circle is simply the length of one complete revolution of the circle.

The circumference of a circle is equal to the diameter (D) times pi (`D*pi` ). The circumference of a circle is also often stated as...

We are given a diameter of 7/22 centimeters.

A diameter is the length of a straight line segment which passes through the center of a circle and has its endpoints on the circle itself.

The circumference of a circle is simply the length of one complete revolution of the circle.

The circumference of a circle is equal to the diameter (D) times pi (`D*pi` ). The circumference of a circle is also often stated as `2*pi*R`  where R is the radius. However, the diameter is simply twice the length of the radius, so we can see the two statements for circumference are equivalent.

`2*R=D` thus

`2*R*pi=D*pi`

So the circumference of our circle is:

`D*pi=(7/22)*pi=0.999 ` centimeters

Recall that the definition of pi is the circumference of a circle divided by its diameter. 

Pi = circumference / diameter = approximately 3.14

Where does the novel The Madwoman in the Attic take place?

TheMadwoman in the Attic is not a novel, but instead a feminist study of a collection of nineteenth-century British novels which are quintessential of the Victorian period. 

The authors, Susan Gubar and Sandra M. Gilbert, are both professors in the fields of Women's Studies and feminist studies. The novel was published in 1979, at the tail-end of second-wave feminism. 

The book takes its inspiration from Charlotte Bronte's Jane Eyre. In that novel, Jane...

The Madwoman in the Attic is not a novel, but instead a feminist study of a collection of nineteenth-century British novels which are quintessential of the Victorian period. 

The authors, Susan Gubar and Sandra M. Gilbert, are both professors in the fields of Women's Studies and feminist studies. The novel was published in 1979, at the tail-end of second-wave feminism. 

The book takes its inspiration from Charlotte Bronte's Jane Eyre. In that novel, Jane encounters Bertha Mason Rochester, the first wife of her employer, Edward Rochester. In Bronte's novel, Bertha is mysterious, crazy, and a burden. Jane is her foil: sweet, orderly, and dutiful. If Jane is the "angel" of the Rochester estate, then Bertha is the "monster," based on the dichotomy created by Gubar and Gilbert. This metaphor coincides with the notion of "the angel in the house," an idea of ideal femininity taken from the title of a poem by Victorian poet Coventry Patmore.

Other authors explored in The Madwoman in the Attic include Emily Bronte, Jane Austen, Mary Shelley, George Eliot, Elizabeth Barrett Browning, Christina Rossetti, and Emily Dickinson. As disparate as this medley of poets and authors is, they all deal with common themes in their work: domesticity, the expectations for middle-class women, romance, and, in the cases of Shelley and Rossetti, aspects of the grotesque and Gothic, a theme that was once also explored by Austen in Northanger Abbey.

Recently, scientist Bill Nye debated on CNN about how we should respond to climate change. What role do you feel the media should play in...

On the level of media coverage of global climate change, I agree with Bill Nye's position that the media should focus on reliable information by scientific experts, serving to educate its audience rather than pander to ignorance and prejudice. While it is important that media coverage be balanced, given limited space and time, that should be a balance among credible accounts with genuine evidence. Balance does not mean treating flat-earthers, creationists, UFO enthusiasts, anti-vaxxers, or...

On the level of media coverage of global climate change, I agree with Bill Nye's position that the media should focus on reliable information by scientific experts, serving to educate its audience rather than pander to ignorance and prejudice. While it is important that media coverage be balanced, given limited space and time, that should be a balance among credible accounts with genuine evidence. Balance does not mean treating flat-earthers, creationists, UFO enthusiasts, anti-vaxxers, or conspiracy theories as though they somehow are on the same level as scientific studies. Nye is doing important work in trying to educate the public about climate change and the way it affects our everyday lives.

In terms of individual freedom, a generally accepted ethical standard is what John Stuart Mill termed the "harm principle" in his seminal work On Liberty. We all accept that our freedom to act ends where it impinges on other people's freedom or causes them harm. I have the freedom to own my own car. I do not have the freedom to steal someone else's car or to drive drunk or to text while driving or to run red lights, as those acts would harm others. In the same way, as Nye points out, carbon emissions harm others. Thus, just to use cars as an example, eliminating lead in gasoline, tightening MPG standards, and limiting emissions all are ways of reducing the harm caused by cars to our environment.

Other measures being advocated by Nye and others concerned about global climate change use scientific evidence to follow this principle that we should be free to take any actions that do not harm others, but that we are not free to act in ways that harm others. Pollution, which degrades the air people breathe and the water people drink, and climate change, which destroys people's homes and increases severe weather events, are examples of harm in the same way drunk driving or stealing are.

How would you describe the Garden of Death in "The Canterville Ghost" by Oscar Wilde?

The Garden of Death is featured in Chapter Five of "The Canterville Ghost," when the ghost tells Virginia Otis of his strong desire to leave Canterville Chase and to sleep forever. 

Though the ghost has not been to the Garden, he has a strong impression of its appearance and atmosphere. It exists beyond the "pine-woods," for example, and is guarded by a "yew tree" which protects the sleepers with its long branches. Inside, the grass...

The Garden of Death is featured in Chapter Five of "The Canterville Ghost," when the ghost tells Virginia Otis of his strong desire to leave Canterville Chase and to sleep forever. 

Though the ghost has not been to the Garden, he has a strong impression of its appearance and atmosphere. It exists beyond the "pine-woods," for example, and is guarded by a "yew tree" which protects the sleepers with its long branches. Inside, the grass is "long and deep" and the earth is "soft" and "brown." The Garden is also decorated with "hemlock flower" and filled with the sound of the nightingale's song.

According to the ghost, there is no sense of time nor place inside the Garden. Furthermore, there exists no today nor tomorrow; no life nor death. The Garden is simply a place of peace where the dead can sleep forever, without fear of ever being disturbed.

What is the significance of Othello's race in Othello by William Shakespeare?

Othello's status as a black man in a white man's world is of vital importance to the plot of Shakespeare's Othello. In defiance of stereotypical and racist assumptions about the black community during Shakespeare's day, Othello is a dignified, honorable man who enjoys considerable power and influence. Moreover, Othello proves himself to be an eloquent and gifted speaker, as he consistently employs sophisticated rhetoric when communicating with his peers. Clearly, Othello deconstructs the racist...

Othello's status as a black man in a white man's world is of vital importance to the plot of Shakespeare's Othello. In defiance of stereotypical and racist assumptions about the black community during Shakespeare's day, Othello is a dignified, honorable man who enjoys considerable power and influence. Moreover, Othello proves himself to be an eloquent and gifted speaker, as he consistently employs sophisticated rhetoric when communicating with his peers. Clearly, Othello deconstructs the racist stereotypes that characterize black individuals as dangerous or uncivilized beings. The fact that he does so invokes the hatred of those white individuals unwilling to accept a black man with intelligence, power, nobility, and dignity. For example, though Iago seeks revenge because he wants the promotion Othello gives to Cassio, we can assume there's a racist subtext underlying this primary motive. Indeed, it's possible to see Iago's plot as the racist effort to oppress a black man who has attained power in a white society. As such, we can see that Othello's race is vitally significant to the play's plot. 

How would you story map Charlie and the Chocolate Factory by Roald Dahl?

While this is going on, we are introduced to Charlie, a kind young boy who lives with his parents and both sets of grandparents. His family...

Exposition: Willy Wonka, a candy factory owner, had closed his factory's doors to the public for a long time. One day, it is revealed that he plans to open the doors once again, but only to a select few people who find Golden Tickets hidden in chocolate bar wrappers.

While this is going on, we are introduced to Charlie, a kind young boy who lives with his parents and both sets of grandparents. His family lives in poverty, but is very close and optimistic.

Rising Action: Charlie finds a Golden Ticket and visits the factory with the other winners (all spoiled, bratty children and their parents). Willy Wonka takes the children through the factory, and each child is picked off one by one due to their greed.  

Climax: Charlie is the last child remaining, and Willy Wonka reveals he plans to give Charlie the factory.

Falling Action: Willy Wonka explains his plan to Charlie and we see the other children leave the factory.

Resolution: Willy Wonka takes Charlie on a ride in his glass elevator, and they go to Charlie's house to tell the rest of his family the news.

Why mass gets converted into energy.

In short, this is can be explained using Einstein's special relativity. Through a few simple thought experiments about time and space Einstein was able to show that Newtonian quantities like momentum, kinetic energy, and total energy are just low speed approximations to the true answers given by special relativity.

In fact those same quantities are.

`P=gamma m v=(mv)/(1-v^2/c^2)^(1/2)`

`K_E=(gamma-1)mc^2`

`E=gamma mc^2`

Now when you preform calculations using the conservation of energy or momentum you will...

Now when you preform calculations using the conservation of energy or momentum you will see that mass is no longer invarient (it changes) like it was in Newtonian physics but can be transformed into energy.

For a simple example, lets say an atom of mass M decays into 2 smaller atoms of equal mass m and that they fly off in opposite directions. The masses of the two atoms would not add up to exactly the original mass. In other words m+m`!=` M. Some of the original mass M has been converted into the kinetic energy of the particles. By this example, the reverse is also true in that 2 perfectly inelastic colliding objects that stick together will create an object that is more massive than the sum of the original two masses (ignoring all other phenomena).
