does anybody know where i can get questions and answers for micro and macro economics?

get my final exam next week, need to read a lot such kinda stuff.

thanks

1. what is semiconductors

2. why metals are good conductors of electricity while semiconductors have relatively poor conductivity?

3.why plastic deformation(eg. cold rolling) and alloying (eg. in stainless steel) affect the electrical resistivity of metals?

4. what is the difference between intrinsic and extrinsic semiconductor?

5.what is the role of doping in the electrical conductivity of semiconductors

6.what's the difference between n-type and p-type semiconductor?

7.what cause the different resistivity values of metals?

8.why semiconductor possess different electrical resistivity?what is the most dominating factor?

i wanna join a table tennis table club, but i must pass the selection which will be held next 2 weeks..

i neva play table tennis before

can i master it in this short time?

i'm studying, so maybe my effective training time is 1week

any tips about this?

1)an area is covered by the curve y=(x)^2 , y = 4 , x = 3 and x axes. calculate the volume when it is rotate 360 degree through

a)the x axes

b)the y axes

c)x = 3

2)an area is covered by the curve y=(x+3)^2 , y = 4 , x = 0 and x axes. calculate the volume when it is rotate 360 degree through

a)x=0

b)y=0

c)x=-3

3)an area is covered by the curve y=(x-3)^2 , y = 4 , x = 0 and x axes. calculate the volume when it is rotate 360 degree through

a)x=0

b)y=0

c)x=3

My friend will be 18 by this august. her height is around 150-157cm .

i think she is short because she didn't eat much when she was in her growing age.. she also eat very little now.. can she grow taller?

i ever heard that there was a boy who was more than 20 year old but his physique is like a kid because he didn't get enough food. but when he's given enough food,he grew more than 10 cm in one week. can my friend grow taller? what should she do or eat?

can you tell me the meaning of:

fire-up

higher end

low end

value chain

bottom line(there are 3 meaning for this)

big hitter

Suppose:

a + b = c

This can also be written as:

4a - 3a + 4b - 3b = 4c - 3c

After reorganizing:

4a + 4b - 4c = 3a + 3b - 3c

Take the constants out of the brackets:

4 * (a+b-c) = 3 * (a+b-c)

Remove the same term left and right:

4 = 3

can anyone explain this?

I don't feel that i'm clever.

There are lot of students who are cleverer than i am in my class.. but i passed the extrance examination in NTU and NUS..while most of my friends failed

I think its a luck, because some of the examination question was about the topic i'd learnt just one day before the test.

I don't really know much about the topic.

i haven't begin my study in any of those university, but i have to decide whether i will study there or not immediately.

my english is not good and i have a financial problem, i can't afford to study in singapore but i can take the tuition grant and financial aid from the university i choose. But if my first year's result is not good, I will have to paid all the money which i have borrow from the university.

Should i take a course in any of those university?

Mathematics?

Physics?

Please state the topic of the lesson

eg:

Mathematics:algebra,vectors,etc

Physics: newton"s 1st law, kinematics,etc

Listening?

Phonetic?

Vocabulary?

Grammar?

Reading?

etc?

please list it....
