In their experiment, rutherford and marsden fired positively charged alpha particles at a very thin sheet of gold. over a period of several months, the scientists made over 100,000 measurements. these measurements showed that a very small number of alpha particles were deflected backwards from the gold foil. use a nuclear model to explain this experimental result.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
