Arecovery cylinder which is half full of recovered r-410a at 90 degrees f, in the absence of non-condensables, will be pressurized to:

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

Looking at this barometer, is the air pressure high or low? what type of weather would you expect? high, bad low, bad high, good low, good

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?
