Two balls of unequal mass are hung from two springs that are not identical. the springs stretch the same distance as the two systems reach equilibrium. then both springs are compressed and released. part a which one oscillates faster? which one oscillates faster? the spring with the heavier ball. the spring with the lighter ball. springs oscillate with the same frequency. it is impossible do determine without additional data.

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
