5. Turpentine oil is flowing through a tube of length 1 and radius r. The pressure
difference between the two ends of the
tube is P. The viscosity of oil is given by
P(2-x)
ne
where v is the velocity of
4v1
oil at a distance x from the axis of the tube
The dimensions of are
(a) (MºLT) (b) (MLT)
(c) (MLT) (d) (ML-T')

12 drag each label to the correct category. decide whether each statement describes mass or weight. measured in newtons measured in kilograms does not change when gravity changes === a gravitational force changes when gravity changes the amount of matter in something mass weight

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix. b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds. c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
