A closed container initially holds 50 monatomic A particles that have a combined energy of 240 units. After 100 monatomic B particles with a combined energy of 360 units are added to the container, the system is allowed to come to thermal equilibrium.
(a) At equilibrium, how many energy units does each A particle have?
(b) At equilibrium, how many energy units does each B particle have?

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
