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.

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
