,specifiedbytriples of (si, fi, bi), defining the start times, finish times, and benefits of each observa- tion request as l = {(1,2,,3,,4,,5,,6,,7,,8,,9,4)}. solve the telescope scheduling problem for this set of observation requests.

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?
