Imagine that you place a little pipette, length 1 cm on
acentrifuge with radius r=70 cm. inside the pippette, there isa
viscous liquid, with viscosity 20 times more than water. inthis
liquid there is a cell of size 1.5 micrometer. the onlyforce that
can provide centripetal acceleartion to the cell is thefriction
force which will develop if the cell moves through theliqid. find
terminal velocity fo the cell assuming centrifugerotates at 1500
rpm. assume cell density is 2 % higher thanwater.
