A70-kg astronaut floating in space in a 110-kg mmu (manned maneuvering unit) experiences an acceleration of 0.029 m/s2 when he fires one of the mmu's thrusters. you may want to review (pages 258 - 260) . for related problemsolving tips and strategies, you may want to view a video tutor solution of acceleration of a rocket. if the speed of the escaping n2 gas relative to the astronaut is 490 m/s, how much gas is used by the thruster in 5.0s and what is the thrust of the thruster?

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.
