Two objects are dropped into beaker with layers of oil, rubbing alcohol, water and corn syrup. these objects are made of the same substance, but object x is twice as large, so twice as heavy as object z.
which of these two objects will settle further down into the beaker, x, z, both or neither?
(my teacher labeled this as a trick question)

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
