Two objects are at rest on a frictionless surface. Object 1 has a mass that is twice that of Object 2. When a constant force is applied to Object 1, it accelerates for a time interval ?t.

You are asked to design a metal alloy for a part with a room temperature application. The part is to be made by casting the metal into shape. When casting the part, liquid metal is poured into a mold that has a cavity with the shape of the part. To reduce cost by conserving energy and to utilize an inexpensive furnace that does not have a high temperature capability, it is desired that the metal alloy not have a high melting temperature. What type of metal alloy phase diagrams should you consider first for this part?
(a) Continuous solid solution (b) Eutectic (c) Compound formation (d) Peritectic

At the end of the star's life, they are dredged up by convection and pushed outward by photons. D. They are forever trapped in the core of the star. E. Low-mass stars do not produce heavy elements.
