Science & Mathematics - 20 November 2006

We're doing stuff with the Ideal Gas Law and I've looked throughout our chapter and our notes and haven't found a problem similar to this. There are so many things missing! Argh. Oh and we also have gone over Thermal Expansion equations if that helps any. Here is the question:

A tank having a volume of 0.100 m3 contains helium gas at 120 atm. How many balloons can the tank blow up if each filled balloon is a sphere 0.300 m in diameter at an absolute pressure of 1.25 atm?

Thanks a bunch!

Suppose a cartesian system is there having "+n" on right axis. There is a mirror image of that system kept apart but in front of it having "+n" on its left axis.There would be a line joining both "+n" of the main system & its mirror image.What would be the nature of such a line joining the "+n" of the main system & the "+n" of its mirror image?

Another question prompted this. How many people from different nation states have you met and talked to (in my case in English)?

And in my case in England.

I will have to get an atlas and run through the list.

Suppose a cartesian system having "+n" points on right side of its axis is there.Its mirror image having "+n" points on left side of its axis is kept apart but in front of it. A line would be there joining "+n" of the main system & "+n" of its mirror image.What would happen to the center of such a line joining those two "+n" of main system & its mirror image?

Solve the equation -9x = 81x^2 . Type your answer(s) exactly in the following form x = a, x = b. Here a and b are your numerical solutions. Leave exactly one space between x, equal sign, and your answer. ^2= 2nd power
How would I write that as a final answer?

A person standing on the edge of a cliff throws a ball straight up with speed 'u', allowing it to crash on to the rocks below. He later throws a ball with the same speed 'u' straight down. Which ball has the higher speed when it hits the rocks? (Neglect air resistance and assume acceleration due to gravity = -10 metres per second per second)
