(a) A very powerful vacuum cleaner has a hose 2.86cm in diameter. With no nozzle on the hose, what is the weight of the heaviest brick it can lift? (b) A very powerful octopus uses one sucker, of diameter 2.86cm, on each side of a shell of a clam in an attempt to pull the shells apart. Find the greatest force the octopus can exert in salt water 32.3m deep.
(a) - I'm not sure how I know the power of the vacuum, but I think I'm suppose to use [tex]P = P_0 + pgh[/tex] although I'm not sure how.
(b) I have no clue how to do this :-\
Could anyone lend a hand?
