- For number 3, you will need to look up the intensity pattern for single-slit diffraction. Presume the electron must be confined within the central, most intense region, which gives you an estimate of position uncertainty.
- I've asked number 6 before.
- Number 7 is a famous thought experiment, it can be found in the wikipedia article on the uncertainty principle.
- Number 8 is a straight math problem (math we'll need soon). Don't let the the unfamiliar terms stump you, all you need to do is integration and algebra for parts a-c.
