b.
c. What is the most stable baryon? = proton
d. What are the decay products of a muon = muon neutrino, electron, anti-electron neutrino
2. Electricity
a. resistance of the resistor
15 Ohms
b. EMF when current = 0.18A
c. When the emf = 4V
3. Double slit
4. Forces and Motion

b.
c.
d.
e. How do these factors affect the maximum range? (???)
Mass
Speed
5. Young's double slit
Maximum intensity. Why is the minimum frequency between C-D (minima) not 0?
Intensity is about the number of photons arriving per second, therefore does not affect frequency.
6. Stationary waves
