Una taza de café de 355 mL es calentada hasta ebullición. Al finalizar el calentamiento, el volumen de café disminuyó a 190 mL. ¿Cuál es el volumen final del café en L? tenga en cuenta que 1 L = 1.000 mL A 355 mL cup of coffee is heated to a boil. At the end of heating, the volume of coffee decreased to 190 mL. What is the final volume of the coffee in L? note that 1 L = 1,000 mL

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
