The Gibbs energy of mixing of a regular solution of components A and B is given by Delta _(mix )G^(real )=nRT(x_(A)lnx_(A)+x_(B)lnx_(B)+eta x_(A)x_(B)), where x_(A) and x_(B) are the mole fractions of the two components and eta is a dimensionless parameter quantifying deviations from ideal behaviour in terms of the relative strength of A-B interactions compared to A-A and B-B interactions. (i) Use a spreadsheet to calculate Delta _(mix )(G^(real ))/(n)RT for x_(A)=0.01,0.125, 0.25,0.5,0.75,0.875 and 0.99 for eta =0,1 and 3. Report your calculations in a table and, using a labelled plot, determine the numbers of minima in Delta _(mix )(G^(real ))/(n)RT as a function of composition and eta . (ii) For each value of eta , predict the number of liquid phases which you would expect for the mixture. Justify your answer in terms of A-B interactions.

In an experiment, neutrons scatter elastically off target nuclei of atomic mass A=30. Assuming the nuclear force has a maximum range of 2fm, and ignoring recoil, estimate the maximum neutron kinetic energy if only S-wave (l=0) scattering is seen.

6. Consider the following control system. 1) Please derive a closed-loop transfer function (3 pt). 2) If the system is subjected to an unit-step input, when does the system enter into the steady-state (3 pt) ? 3) If the system is subjected to a unit-ramp input, derive a time-domain solution using the partial-fraction expansion and derive the steady-state error (16 pt).

According to Schachter's two-factor theory of emotion emotions develop because of their adaptive value . emotion occurs when the thalamus sends signals simultaneously to the cortex and to the autonomic nervous system . different patterns of autonomic activation lead to the experience of different emotions. the experience of emotion depends on autonomic arousal and your cognitive interpretation of that arousal.
