1. A 55kg Olympic diver can jump .65 m high on solid ground. With the help of bouncing on the diving board, she can jump 2.5 m above the board. How much elastic energy is stored in the diving board? (Hint: make the initial situation when the diving board is bent down the most and the final situation when the diver is at her highest point.)

i. like it i'm gonna edit it tomorrow

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.
