1. In a collision between an a particle and an electron, what general considerations limit the momentum transfer? Does the fact that the force is Coulombic play any role in this respect?
2. How does the Thomson atom differ from a random distribution of protons and electrons in a spherical region?
3. List objections to the Thomson model of the atom.
A 315 kg sailboat has an acceleration of 0.72 m/s2 at an angle of 33° north of east. compute direction of the net force that acts on the sailboat
Why doesn't the repulsive electric force of protons in the atomic nucleus cause the protons to fly apart? What is meant by the half-life of a radioactive sample? Why is there more carbon-14 in living bones than in once-living ancient bones of the sam..
