The highest that George can suck water up a very long straw is 2.0 m. (This is a typical value.)
What is the lowest pressure that he can maintain in his mouth?
The weight of the water must equal the difference in pressure.
atmospheric pressure-his pressure=weight 2M water.
check my figuring.
you's the best
Sorry, I meant you are the BEST
There is an error. 2*9.8=19.6, not 18.6
oh i figured that...thanks again
