Un cubo de acero de 20 cm de arista se sumerge totalmente en agua. Si tienen un peso de 564.48 N, calcular. Que empuje recibe Cuál será su peso aparente del cubo

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.
