ok for science project i have to draw a table with a voltagew and its corresponding current could some one help?For 2V 4V 6V 8V AND 10V, what would be the the corresponding current in Amps?if there is no definite awnser, could someone give an intelligent guess as i have no idea......?thanks!

When Einstein's made this test he said that only 2% of people can solve it. I know the test and i solve it but in 2 hours. The real question is: some people say only 2% can solve it under 15 minutes. True or false?

Is time just a measurement of duration or is it an actual part of the universe that can be manipulated? Can I travel faster than time? I've heard that time is the 4th dimension after the 3 dimensions of space, can someone explain this further?

For my history final at school, we have to pick a topic or time period in American history and make a theme park out of it, drawing the park on poster board and writing a paper which explains each attraction. I chose the history of American aviation and I wanted to include a ride themed after the Bell X-1 (1st plane to break the sound barrier) which works like a rocket sled and actually breaks the sound barrier. I was going to say in the paper that the track was one mile, but just so I don't sound like an idiot I figured i'd get a more professional opinion.

Bacteria grow very quickly.
They reproduce about every 20 minutes.

It has been estimated that if unlimited space and food were avaliable for a single bacterium, after 2 days of reproduction there would be a mass about 4000 times that of the Earth.

yeah right!! anyone with me?

Here's the problem:
A bowling ball 25 cm in diameter is slid down an alley with which it has a coefficient of sliding friction of µ = 0.55. The ball has an initial velocity of 9 m/s and no rotation. g = 9.81 m/s2. Note: For a sphere Icm = (2/5)mr2

a) What is the initial deceleration of the ball?
b) What is the initial angular acceleration of the ball?
c) How long does it take before the ball starts to roll without slipping?
d) If it had been moving 11.7 m/s initially, how long would it have taken the ball to start rolling without slipping?
