In an out of control ceramics workshop, two clay balls collide in mid air and stick together. The first has mass 3.12 kg and collides with a second that is initially at rest. The composite system moves with a speed equal to one-third the original speed of the 3.12 kg ball. What is the mass of the second sphere

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
