Explain the operation of a long channel mosfet including an explanation of the roleof the gate and drain in causing current ow. include diagrams of the fet showinghow the depletion and inversion regions change with the applied voltage, and includethe corresponding i-v characteristics.

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?

Abarometer contains mercury with a density of 13600 kg/m3. atmospheric conditions are 95.8 kpa and 20 °c at 20 °c, the vapor pressure of the mercury is 0.000173 kpa. the column of mercury will rise to a height of most nearly. select one: a)- 0.38 m b)- 0.82 m c)- 0.48 m d)- 0.72 m

What is the major difference between thermoplastics and thermosetting plastics from the polymerization structure point of view?
