Consider a copper-based material containing precipitates with an average spacing of 500 nm. The contribution of these precipitates to the yield strength of the alloy is 200 MPa. If the precipitate spacing were decreased to 200 nm, what would be the new contribution of the precipitates to the yield strength of the alloy?

Bob camina 200 m sur, luego trota 400 m suroeste, luego camina 200 m en una dirección 30? norte del este. a. dibuje una gráfica de los movimientos de bob. use una regla y transportador. b. use método gráfico y analíitico para hallar el desplazamiento total que bob recorrió. (magnitud y dirección) c. compare los resultados obtenidos por el método gráfico y analítico. (por ciento de diferencia).

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.
