How does J.K. Rowling's use symbolism in Harry Potter and the Sorcerer's Stone?

The most important symbol in the novel Harry Potter
and the Sorcerer's Stone is the scar on Harry's forehead. The scar represents Harry's
past, his present, and his future.

The scar is representative of
Harry's link to Lord Voldemort. Voldemort is the one who gave Harry the scar as a young child
when he murdered Harry's parents. The scar forces people to become instantly drawn to Harry based
upon the prophecy of his rise.

Another symbol in the novel is the
names associated with each of the different houses at Hogwarts. Perhaps the most telling house is
that of Slytherin. The image of the house is that of the snake. Historically, as far back to Adam
and Eve, the image of the snake represents evil.

One last symbol is
the game of Quidditch. The game not only brings pride to each house, it represents the importance
of values.

Benjamin Franklin as the first fireman in Fahrenheit 451.Why do you think the firemen’s rulebook credited Benjamin Franklin – writer,...

I was actually thinking about this question yesterday, and
I'm a teacher!  ha ha!  I'm not totally satisfied by the answer you have already been
given.  Franklin was very wise...

My mind started to wander
more to the fact that Franklin was partially responsible for bringing newspapers to
America (his brother actually started it), and that Franklin was a BOOK PRINTER,
hello...  The answer has to be in there somewhere.

I was
thinking of two possible things.  1)  people in the book don't know a whole lot because
of the way society is set up, but they would likely know of Ben Franklin, and would buy
him as some kind of authority.  If he is in to what the firemen do, then we can all just
accept it.  or  2)  Since in reality he is a symbol of literacy, maybe they are making
up this lie in order to discredit immediately what a dissenter might say.  For instance,
if Clarisse were to say "well, Ben Franklin said it's really important to read!"  Beatty
would say, "shut up girl, he was the original fireman."

I'd
like to ask Ray Bradbury personally because I'm not all that
sure.

What is at stake in the story?"The Interlopers" by Saki

In Saki's "The Interlopers," more than land ownership at stake
is the pride of each of the feuding sides in their enmity over the "most jealously guarded of
all...territorial possessions."  For this "neighbor feud" has grown into that of a personal one
that has been handed down to Ulrich von Gradwitz since he has become the head of his
family.

Even when Ulrich and his archenemy George Znaeym are trapped
beneath the branches of beech tree struck by the violence of the storm, they cling to this pride
in their feud, boasting each that their men will be the first to arrive and deal with their
enemy:

"So your're not
killed, as you ought to be, but you're caught, anyway," he cried; "caught fast.  Ho, what a jest,
Ulrich von Gradwitz snared in his stolen forest.  There's real justice for
you!"

"I'm caught in my own forest-land," retorted Ulrich.  "When my
men come to release us you will wish, perhaps, that you were in a better plight than caught
poaching on a neighbor's land, shame on
you."

As the men lie pinned beneath
the tree, there is a "bitterness of possible defeat" that courses through each of them until they
finally realize that more is at stake than their prides: other interlopers come--wolves--and now
their very lives are at stake.

In The Hobbit, what are the "call to adventure" and "meeting the mentor" segments of the Hero's Journey?

In the Hero’s Journey, the hero is an ordinary person who
embarks on a journey of self-discovery to become a hero.  In The
Hobbit, Bilbo is a happy-go-lucky and somewhat hapless Hobbit who ends up
going on an adventure because his friend Gandalf the wizard needs a
burglar.

The hero’s journey always begins with a call to
adventure.  The hero can either reject or accept the call.  More often than not, the
hero (who is not a hero yet) rejects the call.  Bilbo rejects Gandalf’s request, and
Gandalf leaves a note on Biblo’s door for the dwarves.  Bilbo is much more interested in
eating and drinking than in adventures, but Gandalf does not allow him to reject the
call to adventure.

Gandalf is Biblo’s mentor for several
reasons.  First of all, he is the one that presents the call to adventure to Bilbo and
does not allow him to reject it.  He also starts Bilbo on his journey, and throughout
the journey he provides him assistance.  In order for the hero to grow he needs to
separated from, and then reunited with, his mentor.  Gandalf leaves Bilbo but does
return later.

How to find the specific heat capacity of a solid (involving a cooling correction)Could you please give me a idea for this experiment?

Well, I can't give you an answer of 600 words, but here is a
general idea on how you can go about it.

First take a liquid of
which you know the specific heat of, water would be ideal to use. Take a measured quantity of
water in a container, so that there is a minimum amount of heat loss. Measure the temperature of
the water.

Now heat the body you want to measure the specific heat
capacity of. Measure its temperature once it has been heated. Then place the body in the
container of water and dip a thermometer in the water. Wait for some time till an equilibrium
temperature is reached.

Once that happens, the heat lost by the body
to decrease its temperature is that absorbed by the water to increase
its.

Now use the specific heat of water that you already know to
find the specific heat of the solid.

I leave it for you to figure
out how that will be done. It’s quite easy and you should know that by
now.

In "The Masque of the Red Death", what chamber is not occupied by the masqueraders and why?

It is important to realise how Poe uses setting
symbolically in this great story. Remember the scene - Prospero has locked himself and
his revellers in a castle in an attempt to cheat death as the mysterious disease, the
Red Death, runs amok outside in the Kingdom killing all in its path. This scenario could
be viewed symbolically as someone trying to cheat death and outrun it, ignoring death's
dominion over human life.

The masque ball therefore is very
significant in terms of its setting. The last, seventh room, is the one where none of
the people wish to enter. Note how it is described:

readability="11">

The panes here were scarlet - a deep blood
colour... in the western or black chamber the effect of the firelight that streamed upon
the dark hanging through the blood-tinted panes, was ghastly in the extreme, and
produced so wild a look upon the countenances of those who entered, that there were few
of the company bold enough to set foot within its precincts at
all.

Note too that in this
suite there is a massive ebony clock. Clearly this is symbolic of the passing of time
and the approaching death of all the guests. The fact that this black room is the most
western, at the rooms run from east to west also indicates the passing of time and the
approaching death, as the sun rises in the east and goes down in the
west.

These guests are engaged in a quest to try and cheat
death and forget about it, therefore it is highly significant that they do not want to
enter this room, which could be said to symbolise death, with the ghastly red light
signifying the Red Death that is about to come upon them all. Also note that it is in
this room that the masked uninvited guest confronts Prospero and death is admitted into
the castle.

The sum of the digits of a 2-digit number is 7. reversing the digit increase the number by 9. Find the numbers?

Let the numbers be xy =
a

Then the reverse number will be yx =
b.

Given the sum of the digits =
7

==> x + y =
7

==> y=
7-x.............(1).

==> b-a =
9

==> (7-x)x - x(7-x) =
9

==> (7-x)*10 + x =
b

==> 70-10x + x =
b

==> 70-9x =
b...........(1)

==> x*10+ (7-x) =
b.

But b-a = 9 ==> a=
b-9

==> x*10+ (7-x) =
b-9

==> 10x + 7 - x + 9 =
b

==> 9x + 16 =
b..............(2)

We will add (1) and
(2).

==> 86 =
2b

==> b= 43

==>
a= 34

==> Then, the two digit
number is 34.

To
check:

3+ 4 =
7

Also, 43 - 34 =
9
