As seen from Earth, the Sun has an apparent magnitude of about 26.7. What is the apparent magnitude of the Sun as seen from Saturn, about 10 AU away? Remember that one AU is the distance from Earth to the Sun and that the brightness decreases as the inverse square of the distance. Would the Sun still be the brightest star in the sky?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
