What is the potential difference between the terminals of an ordinary aa or aaa battery? (if you’re not sure, find one and look at the label.)

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.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
