Cuando el estudiante mantiene extendidos sus brazos horizontalmente, los objetos distan a 1.0 m respecto al eje de rotación y éste gira con una rapidez angular de 0.75 rad/s; el momento de inercia del estudiante y la silla, tienen y una magnitud constante de 3 kg .m². Suponiendo que el estudiante jalará los objetos horizontalmente a 0.30 m del eje de rotación, determinar: a) La nueva rapidez angular del estudiante. b) La energía cinética del estudiante antes y después de que los objetos sean aproximados al eje de rotación

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

the components of a vector are the parts of the vectors that are to each other.
