Apiston-cylinder device initially contains 0.15-kg steam at 3.5mpa, superheated by 5 degrees c. now the steam loses heat tothe surroundings and the piston moves down, hitting a set of stopsat which point the cylinder contains saturated liquid water. the cooling continues until the cylinder contains water at 200degree c. determine (a) the final pressure and the quality(if mixture), (b) boundary work, (c) the mount of heat transferwhen the piston first stops, (d) and the total heat transfer.

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
