EXAM 1 NOTES The actual pressure at a given position is called the absolute pressure‚ and it is measured relative to absolute vacuum (i.e.‚ absolute zero pressure). Most pressure-measuring devices‚ however‚ are calibrated to read zero in the atmosphere (Fig. 3–2)‚ and so they indicate the difference between the absolute pressure and the local atmospheric pressure. This difference is called the gage pressure. Pgage = Pabs - Patm The pressure at a point in a fluid has the same magnitude in all

I fear this essay may come off a bit choppy due to the fact that while reading “The Cathedral” by Raymond Carver I had a lot of different questions and thoughts running through my head. The first thing I noticed was that the narrator never really uses names and that confused me. Making the story difficult to navigate and raising the question‚ why leave character names a mystery until later? What purpose does it serve? We never learn the names of the narrator‚ the wife or the officer‚ most of the

the cause(s) of road accident in developing countries is the mechanic who repairs the various vehicles before the vehicles hits the road. Though many attempted to suggest that a vehicle which is not roadworthy is a source of accident‚ they failed to propose means by which this could be rectified in a holistic way. Laws could be enacted to prevent vehicles not roadworthy from operating on the roads but between the two gaps the mechanic plays a significant role in preventing such road accidents occurring

POPULAR CULTURE By definition‚ popular culture is associated with the everyday‚ the mainstream and that which is commonly accessible: in short‚ culture produced for mass consumption. If there’s one thing people like to consume more than almost anything else‚ it’s popular culture. Television‚ music‚ movies.

The narrator is stereotypical

reading it is even possible to begin to question and wonder why the short story was printed three times‚ with three different titles: “Mine‚” “Popular Mechanics‚” and finally “Little Things”. The differences are between the first and second publications “Mine” and “Popular Mechanics.” The third publication “Little Things” is different from “Popular Mechanics” in title only‚ which again forces you to wonder why there was the need to print the same basic story so many times. Like with many other things
