Question Solved1 Answer PROBLEM 2 Let's work some more with nitrogen. Assume that you five moles of it that expand from an initial state of 3 bar and 88°C to a final state of 1 bar and 88°C. Again you can treat nitrogen as an ideal gas. Answer the following questions for each of the following processes: (a) The first process is isothermal expansion. (i) Draw the path on PV diagram PROBLEM 2 Let's work some more with nitrogen. Assume that you five moles of it that expand from an initial state of 3 bar and 88°C to a final state of 1 bar and 88°C. Again you can treat nitrogen as an ideal gas. Answer the following questions for each of the following processes: (a) The first process is isothermal expansion. (i) Draw the path on PV diagram and label it path A. (ii) Calculate the following: W, Q, AU, AH. (b) The second process is heating at constant pressure followed by cooling at constant vol- ume. (i) Draw the path on PV diagram and label it path B. (ii) Calculate the following: W, Q, ΔU, ΔΗ.

JAVA language Given a sorted list of integers, output the middle integer. A negative number indicates the end of the input (the negative number is not a part of the sorted list). Assume the number of integers is always odd. Ex: If the input is: 2 3 4 8 11 - 1 the output is: Middle item: 4

8.50. An alpha particle of mass 4 u moving with a velocity 2000 m/s collides with a carbon atom of mass 12 u at rest. The alpha particle is scattered through an angle of 30°. Considering the collision to be perfectly elastic, calculate the velocities of both particles after collision and the scattering angle of the recoiling carbon. Describe this collision in the CMCS.

Show that if A and B are matrices which don’t commute, then eA+B = eAeB, but if they do commute then the relation holds. Hint: Write out several terms of the infinite series for eA, eB, and eA+B and do the multiplications carefully assuming that A and B don’t commute. Then see what happens if they do commute.
