Which statement is an example of macroscopic energy creating a microscopic result?(1 point)
Heat is applied to a solid, causing its molecules to move quickly.
The bonds that hold the nuclei of two atoms are broken when the atoms collide, creating heat.
The chemicals in fireworks oxidize quickly, producing a popping noise.
The excited electrons in neon gas drop to a lower energy level, creating visible light.

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?

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
