Correct me if i'm wrong, but if you put a glass of water outside when the relative humidity is 100%, the will not ?

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?

Give an example in which the electrical energy changes to light energy

At what time will the interfering waves have an amplitudeof zero?
