At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 2.75 m/s, and an 86.0-kg person feels a 253-N force pressing against his back. What is the radius of a chamber?
Spherical proteins of an unknown
radius have a density of 6.60 x 103 kg
/m3 and are suspended in blood
which has a viscosity 3.5 times that of
water. The mixture is placed in a
centrifuge of radius 10.8 cm which
spins at 9000 rpm. If the proteins
have a terminal velocity of 2.10 x
10-6 m/s, what is their radius?
Express your answer to two decimal
places in units of nanometers (1x
10-9m).
Spherical proteins of an unknown radius have a density of 5.80 x 103 kg/m3 and are suspended in blood which has a viscosity 3.5 times that of water.
