Is it possible to have a copper–silver alloy that, at equilibrium, consists of a phase of composition 92 wt% ag–8 wt% cu and also a liquid phase of composition 76 wt% ag–24 wt% cu? if so, what will be the approximate temperature of the alloy? if this is not possible, explain why.

Why is metal often used for cooking pan?

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.
