Science & Mathematics - 3 February 2007

I'm taking an ACT prep class and my math one is extra difficult. I didnt know all those trigonomitry and geometry questions would be on there/ i'm only good at solving algebra equations. I couldnt figure any of that stuff out. and my prep teacher teaches too fast for me to keep up. what am I going to do? my math class if over now, what in the world am I going to do? HELP ME! I want to go to a good college!

I ask after reading several things about archeological digs they often refer to the ground level for said times (like what was the groung level in Rome 400 years ago is many feet below the surface now) is where they need to reach to find interesting artifacts. How does the Earth gain so much soil the past surface level is constantly buried?

How can I calculate the amount of input force I would need with each turn of the handle and the total amount of force to raise the books with the distance of 20 cm.
the handle has a circumference of 150 cm., the pitch is 2 cm. and the books weigh 10 kg.
would it be F=2pir or W*P/2pir
If i used a pulley system using the same books which one of these machines will have greatest mechanical advantage.

Why does the magnitude of current depend on potential difference (i.e. - greater potential, greater current)?

- I understand that current is the rate at which charge passes through a conductor.
-And, I understand that the potential difference is the basically how much work (energy) per unit charge is needed to move a charge from one point to another.

But, is there an explanation as to why greater potential difference means greater current?

IS it true that Twins have a sense of knowing were the other is or how they feel? Is it possible that there is such a phenomenon as this.
