Three liquids with different densities are dumped into a glass. what do you expect to see?
a. the liquids will float depending on buoyancy
b. all three liquids will combine to equal the density of the water
c. the liquids will separate according to temperature
d. fluid pressure will cause the three liquids to mix evenly

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
