When performing a melting point on a solid compound, 2 melting point determinations were made. one sample, which was 1 mm in height in the capillary, possessed a melting point of 250-251°c. the other sample was 25 mm in height. what would you expect the approximate melting point to be for this 25 mm sample, if the heating rate for both samples was 2 degrees per minute? (hint: use algebra to solve the mp range) 4. 5. for the same solid compound as the question above, if the 1 mm sample was heated at 15 per minute on a gallenkamp melting point apparatus, what would you expect for an approximate melting point? (algebra may be used again! )

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
