Fahad

I'm studying electrical engineering, and I have an English course that requires me to write a report ...

the problem is, how to find a topic ? the theme for the report is Cities and Towns and I MUST relate my major to that theme and come up with a problem and solution in the report.

I thought a lot, but couldn't find a connection between them with a problem.

I thought of describing the process of generation, transportation and distribution of electric power, but what is the problem here ?

I need some ideas PLEAAAAAASE

so I have this question that was solved our instructor. but when I revised it, it seemed there is a mistake

have a look and see please if there is a mistake or not. 10 points for the first correct answer

I've tried my best to solve it but couldn't :S please anyoen can help me to solve this problem ?

here is the link to it

I couldnt solve it because it requires some math technique

I'm noob in the game :)

Hey , I have macbook pro 13" i7 2.8 GHz processor , how can I download movies ? What application do I have use or download ?

NOTE: Im really noob at computers . so please , explain step by step .

Is it correct to say

We have a lot of studying , so .....( bla bla )

or

We have a lot of study , so ...( bla bla )

???

I have MacBook Pro 13" & 2.8 GHz processor , and I have to download games on a hardisk to play.

the Question is , Is it possible to do this ? I mean , Am I going to face some problems ?

I want to download it in a hard disk because the game takes a huge space on my laptop so , I already have a hard disk .

- BTW , I'm really bad at computers :P so don't laugh at me if this question is silly .

But I'm damn good at math and physics :D

Two long straight wires penetrate the plane of the paper at two vertices of an equilateral triangle of side 4 cm . They each carry 2.0 A, out of the page. The magnetic field at the third vertex has magnitude (inT):

explain please

FOR GOD SAKE help me on that question ( explain please )

A light bulb is rated at 0.40 A and 3.0 V. At 20 Celsius, the bulb filament has a resistance of 2.0 Ω. If the filament is made of tungsten, what is the temperature of the filament when bulb is on? The temperature coefficient of resistivity for tungsten is 4.5 E-3 K-1.

i know the answer , is is 630 Celsius but HOW please explain

thanks

A conceptual qustion ,

If (Summation) an is a convergent series with positive terms , is it true that (Summation) sin(an) is also convergent ??

I know the answer , it is true , but why ?? the book uses Limit Comparison test when he assumed

bn = sin(an) , but the question is , how can he uses it while sin(an) is not always > 0 ???????

So I have this homework , I;ve finished it but I just want to make sure that I've done it right

1) A 25-ohm resistor has a constant current. If 3,460C of charge flows through it in 7 minutes what

is the value of the current?

( MY ANSWER IS 8.2 amberes )

2) A wire with a length of 150m and a radius of 0.14mm carries a current with a uniform current density of 5.6 x 107 A/m2. What is the value of the current.

( MY ANSWER IS 3.4 amberes )

3) Copper contains 6.3 x1028 free electrons/m3. A copper wire of radius 3.53 x 10-4 m2 carries a current of 1.95A. What is the electron drift speed approximately?

( I couldn't solve this please )

please check if my answers are right or not , and help me for the third question please

Evaluate

Integral [ (sinx)^2 (cosx)^4 dx ]

Capacitors A and B are identical. Capacitors A is charged so that it stores 4.0 J of energy and capacitor B is uncharged. The capacitors are then connected in parallel. The total energy stored in the capacitors is

explain the answer pleaseeeeeeee

Capacitors A and B are identical. Capacitors A is charged so that it stores 4.0 J of energy and capacitor B is uncharged. The capacitors are then connected in parallel. The total energy stored in the capacitors is

A) 1 j

B) 2 j

c) 4 j

d) 8 j

e) 16 j

integral [ In( 2 x^2 In sqrt(x) ) / x ]

Is there a way in ( Dev C) to write a condition in if statement to findhe highest value among given values ?

if yes , please help me

thanks

For GOD sake , can anyone do this little program ? I've worked my *** off but I couldn't get it right , here is the question :

Using a while loop, write a C program to display a positive integer number typed by the user in reverse

for example you typed 123 , it'll display 321

thanks

I've been thinking a lot and a lot , BUT I COULDNT find the mistake in this program c++ code

first , I want to describe pythogorean theaorm such that the user enters 3 integers and the program calculate if the sum of the squares of any 2 integers equal the square of the 3rd integer it displays a message saying a^2 + c^2 = b^2 for example , esle , it says they don't form a pythagorean triple , here is the program i wrote :

#include <stdio.h>

#include <math.h>

int main ()

{

int a , b , c ;

printf("Enter any three integers > ");

scanf("%d%d%d",&a,&b,&c);

if ( pow(a,2) + pow(b ,2) == pow (c,2) )

printf("Pythagorean triple %d^2 + %d^2 = %d^2 ",a , b , c);

else if ( pow(c,2) + pow(b ,2) == pow (a,2))

printf("Pythagorean triple %d^2 + %d^2 = %d^2 ",c , b , a);

else if ( pow(c,2) + pow(a ,2) == pow (b,2))

printf("Pythagorean triple %d^2 + %d^2 = %d^2 ",c , a , b);

else printf(" %d , %d and %d do not form a Pythagorean triple \n " , a , b , c );

system("pause");

return 0;

}

Consider all possible isothermal contractions of an ideal gas. The change in entropy of the gas:

1. decreases for all of them

2. does not increase for any of them

3. does not decrease for any of them

4. is zero for all of them

5. increases for all of them
