Select the correct answers.
when you throw a ball upward, its kinetic energy (decreases, increases, or remains the same) and its potential energy (decreases, increases, or remains the same) . when the ball reaches maximum height, its kinetic energy is at a (maximum, or minimum).

What are the three ways that an object can accelerate

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)
