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. The mixture is placed in a centrifuge of radius 10.1 cm which spins at 9000 rpm. If the proteins have a terminal velocity of 3.70 x10-6 m/s, what is their radius? Express your answer to two decimal places in units of nanometers (1x10-9m), but do not include units in your answer.

An automobile tire is shown in the figure below. The tire is made of rubber with a uniform density of 10✕103 kg/m3. The tire can be modeled as consisting of two flat sidewalls and a tread region. Each of the sidewalls has an inner radius of 16.5 cm and an outer radius of 30.5 cm as shown, and a uniform thickness of 0.660 cm. The tread region can be approximated as having a uniform thickness of 2.50 cm (that is, its inner radius is 30.5 cm and outer radius is 33.0 cm as shown) and a width of 21.4 cm. What is the moment of inertia (in kg · m2) of the tire about an axis perpendicular to the page through its center?
