Let's practice calculating the frictional force of a skier on old "woody" skis and wet snow. the skier has a mass of 58 kg. the coefficient of kinetic friction of wood skis on wet snow is 0.1 notice there are no units for the coefficient of friction. what is the kinetic frictional force between the wood skis and the snow

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.
