Whats Othello about, in 6 sentences or less?

Yuugib

The play is about the evilness of people and how they can be easily manipulated. Othello is driven to madness by Iago, who has brought the green-eyed monster on him. Othello is so blinded by this, that he fails to realise the truth and innosence of his wife and friends. In the end he ends up murduring his wife, setts up traps to kill his friend and finally kills him self when he realises that he was wrong about the whole jelousy situation.

F= ma = M x V x Omega = (mv^2)/r = M x Omega^2 x R

for 10 marks I'd give that 6/10 but thats an amateur's take on it. You start of good by discussing the themes of evilness (not a word btw... and can i suggest 'morality'?) and manipulation; truth and innocence. I assume the Green Eyed monster is envy? Having not ever read Othello mind you.

"Othello portrays misplaced trust, immorality and manipulation. Driven to mad envy by his friend Iago and a Green-Eyed Monster, Othello is blinded from the innocent nature of his wife and loved ones." <-- at this point I'd have added more to be honest, but again I havent read Othello but I'm sure theres more you can say here: What moral did Othello learn from his ordeal in the end? What did Iago become? Why did Iago manipulate Othello?

wou maybe I can extract the whole play out of you this way

que?

An the inverse square law that governs two bodies states that 2 point masses attract each other with a force directly proportional to the product of their masses, and inversely proportional to the square distance between them.

Gravity: (G x M1 x M2) / d^2 where G is the gravitational Constant

Charges: [1/(4 x pi x e)] X [(Q1 x Q2) / d^2] <-- where 1/4x pi x e accounts for the permitivity of the medium (eg. a vaccum or air)

the Photoelectric law is not one of the inverse square laws. I was mistaken and there appears to be only 2 such laws in the course.

Recite word perfect (hopefully from memory) Newton's 3 laws of motion.

Cokehead Mother

A particle will move at constant velocity unless acted on by a force.

The rate of change in momentum of a particle is proportional to the applied force and takes place in the direction of the force.

Every action has an equal and opposite reaction.

Not word perfect, but the gist is there.

How would one factorise x^3 - y^3?

Pretty sure that the above would give you a positive y^3 when he wants - y^3

Without thinking about it enough to be sure I'm right I'd just go for difference of 2 squares and say:
(x^3/2 + y^3/2) (x^3/2 - y^3/2 )

crud... i had physics mocks today, mother of god it was DIABOLICAL.
Hahah most of the 56 markers i scraped about 12marks.

BUT i did know my electricity hup, and it came up and i kicked ass but other than that it was terrible.
But does somebody want to answer this :

"When a gun fires a bullet the kinetic energy gained by the bullet is much greater than that gained by the gun. Explain "

couldnt quite manage it today... yes , i know it's probably shockingly easy.

jakedixon2004

Is that Higher or ordinary?

Cokehead Mother

Kinetic energy equals (1/2)(m)(v^2)

So even though the m of the gun is a lot bigger, v^2 is like teeny compared to the bullet's v^2 so it works out much less.

But that's really just an assumption so I dunno if you'd get the marks for it.

Nobody answered the last Q so I won't ask one.

daggy

That's pretty much what i wrote... bit of waffle.
mmkay. It's higher !

Overheal

Under the principle of Conservation of Momentum:

Momentum before firing = Momentum After firing

M[gun]*u[gun] + M[bullet]*u[bullet] = M[gun]*V[gun] + M[bullet]*v[bullet]

Example: If the gun is 3kg and the bullet is 0.03kg we have:

3*0 + 0.03*0 = 3*v[gun] + 0.03*v[bullet]

*algebra*: 0 = 3*vG + 0.03vB

so: 3*vG = 0.03*vB

hence the velocity of the bullet B will be much greater than the velocity of the gun G; which satisfies the Principle of Conservation of Momentum [and satisfying its equation]. for instance if the velocity attained by the gun was 1ms^-1 , the bullet of much lower mass would need a velocity of 100ms^-1 to balance the equation.

This also holds true for the conservation of energy, so that

---

>> the Energy before the reaction = Energy after

---

>> Energy of the bullet = Energy of the gun

---

>> (1/2*m*v^2 = 1/2*m*v^2) so you can make the same arguing point. You may assume no energy is lost in the reaction to outside influences (heat, light, sound, etc.) unless the question specifies there is energy lost in the reaction.

The law of Deminishing marginal returns states that as more and more of a variable factor is added to a fixed factor, a stage will enentually be reached where returns begin to decline.

Well if energy of gun is equal to the energy of the bullet then you are saying that the kinetic energy of the bullet is the same as that of the guns but it isn't?

You see the Conservation of Energy has being misused here.
TOTAL ENERGY BEFORE = TOTAL ENERGY AFTER
Chemical Energy stored in Bullet = Kinetic of Gun + Kinetic of Bullet + sound/heat/etc.

But, by means of example, one can see that the kinetic energies are not necessarily split 50:50 between bullet and gun.

Kinetic Energy depends on both mass and velocity. But as a previous poster said the velocity is the primary factor as it is squared. I would suggest that is why the question stated much greater than.

As for answer I wouldn't be sure what to write down!

aye that is precisely it! dont sound so shocked ok, chill!

Cokehead Mother

Aaah right. When I say xn, I mean x^n

So let f(x) = ax3 + bx2 + cx + d

Then f(k) = ak3 +bk2 +ck + d

f(x) - f(k) = ax3 + bx2 + cx + d - [ ak3 +bk2 +ck + d ]

f(x) - f(k) = a(x3 - k3) + b(x2 - k2) + c(x - k)

f(x) - f(k) = a(x - k)(x2 + xy + k2) + b(x - k)(x + k) + c (x - k)

f(x) - f(k) = {x - k}[a(x2 + xy + k2) + b(x + k) + c]

Thus, x - k is a factor of f(x) - f(k)

If f(k) = 0, then x - k is a factor of f(x)

Typing maths is so awkward. Who wants to prove the product rule?

alan4cult

Right product rule:

y = uv
ln(y) = ln(uv)
ln(y) = ln(u) + ln(v)
d/dx ln(Y) = d/dx ln(u) + d/dx ln(v)
1/y(dy/dx) = 1/u(du/dx) + 1/v(dv/dx)
dy/dx = y/u(du/dx) + y/v(dv/dx)
dy/dx = uv/u(du/dx) + uv/v(dv/dx)
dy/dx = v(du/dx) + u(dv/dx)

take it up with your teacher by all means...

I'll have another stab:

TOTAL ENERGY BEFORE = TOTAL ENERGY AFTER

Chemical Energy = Kinetic Energy [+ loss]

The 2 bodies, are acted on by the same force: the explosion of the round in the chamber, (denoted by 1/2*m*v*^2).

Basic physics (you can use a number of formulas to show it but its common sense) would show that if the same force acts on a large body (relatively) and a small body, it requires less energy to accelerate the smaller mass. In this case, the bullet. Hence if the same force were to act equally on both masses, the inherited velocity of the smaller mass (bullet) would be greater than that of the larger mass (gun).

To answer Timans' question first. The factors that affect PED are:
-the Number of Substitute Goods Available
-the percentage of income spent on the product
-whether the good is a neccessity or a luxury
-Goods in Joint Demand
-Durabilty of Product
Can't remember anymore of them, there's another two I think


In response to the last poster, Niamhd164, 'Wie war das Moglich?' was said by John Montague, can't remember the name of the poem though. It was the one with the images of the war on the screen which he saw as a child or something like that. It means 'How was that possible?'
