Abee goes out from its hive in a spiral path given in plane polar coordinates by r= bekt a = ct where b, c and k are positive constants. show that the angle between the velocity and acceleration vectors remains constant as the bee moves outward (hint: find v. a/va).

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.
