How far will Otilio travel in 6 sec if his speed is 2 m/sec?

What are the differences and similarities of a compression wave and a transverse wave?

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)

Why is it important always to use horizontal bars in unit fractions when performing unit conversions?
