My notes a container is divided into two equal compartments by a partition. one compartment is initially filled with helium at a temperature of 240 k; the other is filled with nitrogen at a temperature of 315 k. both gases are at the same pressure. if we remove the partition and allow the gases to mix, what will be their final temperature?

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.
