Science & Mathematics - 14 December 2007

I'm drinking jim beam and cola cans, but nearly ran out (its nearly 8pm here in aus!), and will have to move onto the bottle next!, (gee, what a shame!), but, the cans are 440ml, at 5% alcohol, and the bottle is 700ml @37%alcohol, so, my question is this!, how much bottled beam do i mix with how much coke, to get the same ratio as the cans?.. and ergo, how much coke would i need to mix the whole bottle at that %age?... thanks in advance, might not be capable of typing them later!...

And if they are really a mass of water vapor particles why is it that we see them as a mass?

1. is it possible to pass light or can you only travel at the same speed as light

2. does time slow when you travel at the speed of light

3. what is the speed of light

4.do black holes suck in light and if so you cannot see them then

How do I find each of these complex numbers and Write the complex number in its usual form? All you have to do is show me one. Thank you.
Complex Number 1: i
Complex Number 2: i2 (so this just means i•i )
Complex Number 3: i3 (so this just means i•i•i )
Complex Number 4: i4 (in other words, i•i•i•i )

A woman has a period practically once a month. The same amount of time the Moon goes round the Earth. It controls the tides and has a strong gravitational control over our surface.

I would like to forward my idea of a black hole and time travel to you in the hope of getting your feedback.

I believe that a black hole is created by a drop of water or water particle in the outer earth’s space.

The water particle is floating along and is struck by a dust particle or something like it and the drop of water or particle implodes.

As the oxygen created from the water goes out faster then something goes in thus creating a black hole which will expand until it fills up with a heavier substance than the hole itself, and consequently closing it.

If my theory is correct, it would make it possible to create a black hole on earth.

This would open up many doors. For example it would be possible to create time travel, well not to travel back in time but to let time past you. ?

1. 9^2x = 27^x - 1

2. 5^n-1 = 1/25

3. 25^x = 5^x2 - 15

4. 2^x * 4^x+5 = 4^2x-1

5. (sqrt3)^2x+4 = 9^x-2

I am looking at moving into a new home. However it has overhead electricity pylons with electricity flowing through it about 50 metres close to the house. The developer states they have done research and its safe. However i am worried about long term risk of cancer.
Please advise
