"La solubilidad de un soluto en un solvente es de 23gr de soluto por cada 100ml de agua, a 20°C. Si se tiene una solución acuosa en la que se disolvieron 2gr de dicho soluto en 100ml de agua": a)¿Se trata de una solución saturada o no saturada? ¿Por qué?
b)¿Se trata de una solución diluida o concentrada? ¿Por qué?

Ahot-air balloonist, rising vertically with a constant speed of 5.00 m/s releases a sandbag at the instant the balloon is 40.0 m above the ground. after it is released, the sandbag encounters no appreciable air drag. compute the velocity of the sandbag at 0.250 s after its release.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

Achild has maximum walking speed of 1.6 m/s. what is the length of the child's legs? 0.26 m
