Determine Kc for the reaction (justify all your calculations):
½ N2(g) + ½ O2(g) + ½ Br2(g) NOBr(g)
From the following information at T=298 K
2NO(g) O2(g) + N2(g) Kc = 2.1 x 10^30
NO(g) + ½ Br2(g) NOBr(g) Kc = 1.4

What is the current thinking on the little hierarchy problem in light of a potential Higgs mass above 120 GeV? A few years ago, at least, I remember various phenomenologists saying that this at least makes life rather difficult for the MSSM.

Goldstein's Classical Mechanics has a puzzling few sentences in his discussion of orbits.
Referring to the case of orbit where the energy is low enough for the orbit to be bounded, he says :"This does not necessarily mean that the orbits are closed. All that can be said is that they are bounded, contained between two circles of radii r1 and r2 with turning points always lying on the circles."
Doesn't "bounded" automatically mean "closed"? The object cannot escape from the attractive force and hence returns over and over. At least, that is my understanding of the terms. Wikipedia says "The orbit can be open (so the object never returns) or closed (returning), depending on the total energy (kinetic + potential energy) of the system." But it also says "Orbiting bodies in closed orbits repeat their paths after a constant period of time." So the only way out I see is if a closed orbit is a special case of non-precessing bounded orbit.

An amusement park studied methods for decreasing the waiting time (minutes) for rides by loading and unloading riders more efficiently. Two alternative loading/unloading methods have been proposed. To account for potential differences due to the type of ride and the possible interaction between the method of loading and unloading and the type of ride, a factorial experiment was designed. Use the following data to test for any significant effect due to the loading and unloading method, the type of ride, and interaction. Use α = 0.05.

|---|---|---|---|
| Roller Coaster | Screaming Demon | Log Flume | |
