We have taken the energy of a simple harmonic oscillator. because we are assuming the atoms are vibrating within a simple harmonic potential. (a) is it justified to take the potential of an simple harmonic oscillator? hint: use taylor series expansion of potential as function of position around minimum] (b) is the potential of simple harmonic oscillator still valid at high tem- perature? determine the higher order correction of potentia (c) is the thermal expansion of solids possible, just taking care of the har monic potential? justify your answer using calculation (d) take correction of potential upto fourth order in displacement and calculate the average displacement of the atoms as a function of tem- perature

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
