Find the ratio of the y velocity of the string to the slope of the string calculated in the previous part. express your answer as a suitable combination of some of the variables ω, k, and vp.

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)

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
