Practical steam engines utilize 475°C steam, which is later exhausted at 300°C. Explicitly show how you follow the steps in the Problem-Solving Strategy for thermodynamics found on pages 361-2 when answering the questions below. (Do this on paper. Your instructor may ask you to turn in this work.)
(a) What is the maximum efficiency that such a heat engine can have?
%
(b) Since 300°C steam is still quite hot, a second steam engine is sometimes operated using the exhaust of the first. What is the maximum efficiency of the second engine if its exhaust has a temperature of 150°C?
(c) What is the overall efficiency of the two engines?
(d) Show that this is the same efficiency as a single Carnot engine operating between 475°C and 150°C.
The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.8 m/s as it passes through the lowest point. Illustrate what is the tension in the rope at that point?

Assume that we suddenly discovered that all these years we would be wrong about the distance from Earth to the Sun, and it is actually 10 percent greater than we would think. How would that affect our approximation of the distance to the Andromeda..
Consider a spherical Gaussian surface and three charges: q1 = 1.62?C , q2 = -2.45?C , and q3 = 3.57?C . Find the electric flux through the Gaussian surface
