An Atwood machine is constructed using two wheels (with the masses concentrated at the
rims). The left wheel has a mass of 2.2 kg and
radius 21.01 cm. The right wheel has a mass
of 2.8 kg and radius 27.87 cm. The hanging
mass on the left is 1.98 kg and on the right
1.1 kg.

Answer in units of m/s.

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? the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. the ice dissolves oxygen from the air, forming a denser crystalline matrix. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.
