4. Car A is standing at red traffic light. Just as the light turns green car B travelling at a constant velocity of 14 m. s- passes car A, which accelerates uniformly at 2.5 ms-2 to a velocity of 18 m. s-1 and then
travels at a constant velocity.

4.2 How long does it take car A to reach a velocity of 18 m. s-1

4.3 Which car is ahead and by how much, when car A reaches a velocity of 18 m. s-1

4.4 How long does it take for the cars to draw level?

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.
