Abaseball player comes to a stop as he slides into a base. which two things slow him down as he slides?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

The coefficient of friction is a number that represents the resistance to sliding between two in contact with one another.

Does science support the idea that humans have influenced global warming? provide specific examples that show how two knowledgeable individuals with differing opinions might argue.
