Steam at 7 bar, dryness fraction 0.9, expands reversibly at constant pressure until the temperature is 200 °c. calculate the work input and heat supplied per unit mass of steam during the process.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
