Choose a scientist from (Democritus, John Dalton, JJ Thomson, Ernest Rutherford, Niels Bohr, Erwin Schrodinger or James Chadwick) . Conduct research using outside sources. Be sure to choose reliable resources such as government, scientific, and educational websites. Document all research in your own words. Be sure to properly cite all sources used in your assignment.
Research and respond to the following:

What were experiences in his life that led to his interest in science and the study of the atom? (3-5 sentences paraphrased)

Defend his work on the atom and its contribution to the modern atomic model. (3-5 sentences paraphrased)

Point out which contributions are present in the modern atomic model and which were eventually disproven and thus are not part of the modern model. (3-5 sentences paraphrased)

Works Cited: List all of the websites used to find the information. You should have at least 2.

A23 kg log of wood begins from rest, 300 m up a sluice (a water track used to transport logs, think of it as an inclined plane with negligible friction) inclined at 20° to the horizontal. after it reaches the flat waterway at the bottom it collides elastically with a 100 kg block of wood initially at rest near the base of the incline. (a) how long does it take the 23 kg log to travel down the incline? (b) what is the speed of the 23 kg log at the bottom of the incline? (c) what are the velocities of both blocks of wood after the collision? (d) what is the total kinetic energy before the collision? (e) what is the kinetic energy of the 23 kg log after the collision? (f) what is the kinetic energy of the 100 kg block of wood after the collision? (g) what is the total kinetic energy after the collision? (h) compare the total initial and total final kinetic energies. is this consistent with what you would expect for elastic collisions? explain!
