1. Democritus, a Greek phlosopher, said that matter is 2. What dpes the Greek word atomos mean? 3. About 350 B.C., Aristotle stated that bath and are continuous 4. What are the five postulates of Daltoan's atomic theary? 5. (a) When electricity was applied to a gas filled seal tube, the tube began ta glow and emit aan (b) This eventually led to the discovery of a negatively charged particle caled alan called a/an and a positively charged particke 6...
2 Atomic Physics The Rutherford model of an atom asserts that electrons move in circular or elliptical orbits about the nucleus They are held in orbit by the Coulomb force. In hydrogen a single electron moves in a circular orbit around a single proton. The radius of a hydrogen atom is 5.3. 10-1 m a) What is the Coulomb force between the proton and the electron? (b) What is the speed of the electron?
a. Describe Mendel’s experiments. b. What was the significance of Mendel’s results? c. Compare and contrast dominance, codominance and incomplete dominance patterns of inheritance. d. Does the discovery of more complex patterns of inheritance than what Mendel described invalidate his findings? Why or why not?

Review Part B An early model of the atom, proposed by Rutherford after his discovery of the atomic nucleus, had a positive point charge +Ze (the nucleus) at the center of a sphere of radius R with uniformly distributed negative charge -Ze. Z is the atomic number, the number of protons in the nucleus and the number of electrons in the negative sphere. What is E at the surface of the atom? Give your answer as a...

In the coordination failure model: a. Describe an example of a coordination failure problem. b. What causes business cycles in the coordination failure model? c. Why money is neutral in the coordination failure model? d. Should the government act to stabilize output in the coordination failure model?
