What is the best part of "Haircut" by Ring Lardner?

It would seem logical that in a short story that is as
painstakingly structured as "Haircut" is, the best part would be the resolution. In a
short story, the resolution holds a surprise ending or a twist to the plot that changes
the import of the story. The resolution also imparts the moral values and confirms the
theme developed throughout story.

"Haircut" is no exception to this
formal rule. The resolution of "Haircut" presents two characters in a different light
from that seen earlier. First, Paul goes on a hunting outing with Jim and seemingly
coolly acts in a way that is disadvantageous to Jim. Second, when Doc Stair is called to
the lakeside where Jim Kendall's body is reposed, he makes a surprising decision. As the
town coroner, he has the ultimate authority for declaring murders accidental or
homicide.

We know that both Doc and Paul Dickson are enraged by both
things that Jim did to Julie (forcing his way into her home and tricking her into going
to Doc's office). We know that Paul nonetheless volunteered to go with Jim hunting. We
know that Doc confided to Paul that "anybody that would do a thing like that ought not
to be let live." We know that "[Paul] let fire and Jim sunk back in the boat, dead." We
know that Doc was worried enough about Paul's thoughts to go looking for him at the
barber shop.

What surprises us is that Doc, acting as town
coroner, immediately passes Jim's death off as a pure and simple
accident:

Doc
examined the body and said they might as well fetch it back to town. They was no use
leavin' it there or callin' a jury, as it was a plain case of accidental
shootin'.

This raises the
questions that Lardner wants us to think about: What is the just dessert for someone
like Jim who's bullying brutality is condoned by the community? What breach of ethics
and morality did Jim's death prompt Doc Stair to commit? What did Paul decide to
intentionally do regarding Jim's life? The resolution is thus the best part of
"Haircut."

Comment on the irony of the father's reflection that "That were awfully young, Wendy and Peter, for death thoughts."

To me, what is ironic about this thought on the part of
the father is that he is worried for the kids' sake when he ought to actually be worried
for his own sake.

When George thinks that the kids are too
young for death thoughts, he is worrying about how they will handle it.  Will this stuff
about death scare them?  He is not sure they are ready for
it.

But what he should really be worried about is his own
life.  Whether his kids are ready for it or not, the death thoughts they are having are
about him and his wife.  The death of some pretend zebras is not going to scare them --
they are planning for the actual death of their
parents.

That, to me, is ironic.

What is the rising and falling action of The Secret Life of Walter Mitty?

In The Secret Life of Walter Mitty, I
think you can point to several points across the plot for the rising
action. At the point when we see Mitty's second day dream and he is a
doctor, we are into the rising action. We have seen the first trigger that puts him into
his dream world: a cranky, nagging wife: her introduction is what I would call the
inciting incident. It begins the rising action. After his
experiences as a doctor, we see continued rising action as the parking lot attendent
catches him mid-daydream. Next, he tries to go buy whatever he was supposed to for his
wife. He turns into a courtroom witness (daydream). Then he goes to buy a buscuit for
the dog (real life). He then becomes a heroic bomber
(daydream).

The climax occurs
when he finally catches up with his wife again... the potential source of his need to
daydream about being successful.

The falling
action is fast in this one, she claims she is going to check into his
health and goes into a store. He remains outside.

Which method is the most suitable for separating a mixture of sodium chloride and iodine?A) crystallization,B) filtration,C) fractional...

Of the choices listed, the best would be sublimation. 
Sublimation is a physical process in which a substance changes from a solid directly to
a gas without passing through the liquid phase. A common example of this process  is dry
ice. When you put a piece of dry ice into a room, you immediately see a cloud forming
around the dry ice. What is happening is that the dry ice is very cold and the CO2 gas
coming off the piece of solid dry ice is cold enough to cause the moisture in the air to
condense, forming the cloud you see.

Mothballs and iodine
are two other substances that will sublime.  To separate the salt and iodine, place both
in a beaker and place a watch glass or evaporating dish on top of the beaker.  Put some
ice in the top of the evaporating dish.  Now gently warm the bottom of the beaker and
the iodine will sublime into a gas. As it rises and hits the bottom of the cold
evaporating dish it will deposit on the underside of the dish  as iodine crystals.  You
can then scrape the iodine crystals off the dish and put them into a container.  The
salt, being a crystalline solid, has a very high melting point and will remain in the
beaker, unaffected by the gentle heating.

I am trying to understand chapter 37 in Uncle Tom's Cabin, "Liberty", better. Can anyone explain that chapter for me in a short summary?

There is a geographical shift that takes place in chapter
37 and the setting is now the Midwest. The reader has followed the fugitive slave hunter
Tom Loker as he has been trying to apprehend Eliza and her family. Since Tom is injured
in the previous chapter, he finds himself being taken care of by a Quaker woman, Dorcas,
in the midwest. He realizes that the fugitives could have left him injured, but instead
chose to help. This fact seems to spark a sort of conversion in Loker, who is generally
an unlikable character. He becomes introspective and advises the Harris family how to
evade the captors. Toward the end, the reader follows Eliza, her husband and child as
they flee toward Canada while Eliza is disguised as a man and little Harry as a girl.
Here Liberty functions in terms of freedom. The text deliberates on the new found
freedom of Eliza, George, and Harry:

Who can speak the blessedness of that first day
of freedom? Is it not the sense of liberty a higher and a finer one than any of the
five? To move, speak, and breathe,-go out and come in unwatched, and free from
danger!

Lastly, though, the
theme of liberty emerges throughout the book and Stowe, the abolitionist, argues that a
country is not truly free until all of its citizens are free.

How do airbags in a car work, won’t the passengers get crushed by it?

You have to understand the complete working of an air bag
before you can ask this question. The most important units of an air bag system are: an
air bag and gas generator, crash sensors and a diagnostic monitoring
unit.

In case of a collision, which is taken to be the car
hitting a barrier at 14.48 km/hr, the crash sensors detect the deceleration and send an
electric current through an initiator. The initiator leads to a solid propellant
undergoing a rapid production of a gas, usually nitrogen, which fills up the airbag in
less than 1/20th of a second. The bag remains inflated for 1/10th of a second and then
gets deflated which takes around 3/10th of a second.

This
is a very essential part of the operation of the airbag mechanism. As you may guess,
just an inflated bag is going to cause a lot of harm if you crash into it, just like you
will injure yourself if you fall from a height even on something soft. The fact that the
air bag inflates and then deflates after a very short duration of time allows it to
absorb the energy of the impact and protects you in case of an
impact.

What mental and emotional effects does the veldt have on the children, the parents, and the psychologist in Bradbury's "The Velt"?

Ray Bradbury's short story "The Veldt," published in 1951,
reflects the concerns of other science fiction writers such as Aldous Huxley
who published Brave New World in 1932:  The advancement of
technology ahead of the advancement of humanity.  Much as in his other short story
"There Will Come Soft Rains," in which the house continues to operate on its own after a
nuclear blast kills all the occupants, the playroom of the Hadley children virtually
controls the lives of the occupants.  The children "live for the nursery," says George
Hadley to his wife.

Thus, there is an uneasiness generated
in the parents as they sense the control that the Veldt room holds upon Wendy and Peter,
their children.  For, the children have alienated themselves from their parents,
expressing no desire to participate in any familial activities such as dinner.  Without
their children to care for, Lydia feels unneeded since the house responds to the
smallest need, such as ketchup.  For instance, when the diningroom table produces warm
dishes of food, George Hadley simply has to ask it for ketchup or anything else and the
item appears.

When the Hadley's friend David McClean, who
is a psychologist, arrives, they ask him to inspect the African veldtland.  Upon
entering this playroom of the children, McClean remarks that it does not "feel
good":

"This
is very bad.  My advice to you is to have the whole damn room torn down and your chidren
brought to me every day during the next year for treatment...In this case the room has
become a channel for destructive thoughts, instead of a release away from
them."

Further, the
psychologist tells George Hadley that he has allowed the room to take the place of him
and his wife in the children's affections.  But, when George tries to shut down the
room, Peter tells his father, "Oh, I hate you...I wish you were dead."  Peter's father
replies that he and his wife were dead, but now they are going to live as a family.  The
house has become what George Hadley has called "a nightmare."  And, the dramatic irony
of George's lines is that he does not realize how nightmarish it
is.
