A block of mass m rests on a 20 degree slope. The coefficients
of static and kinetic friction are 0.80 and 0.50, respectively. The
string is massless and the pulley is frictionless and massless.

When a muscle is stimulated to contract aerobicaly, less lactic acid is formed than when it contracts anaerobically because a. glycolysis does not occur to significant extent under aerobic conditions b. under aerobic conditions in muscle, the major energy-yielding pathway is the pentose phosphate pathway, which does not produce lactate c. under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactat d. muscle is metabolically less active under aerobic than anaerobic conditions
9. (15 points) Show that if n is a positive integer then L() = n(n + 1)2 =3 k=0 10. (BONUS) Consider the following discrete time process: at integer times, a marble arrives which can be one of m colors. Each color is equally likely; all events at different times are independent. As each marble arrives, it is placed into a bowl Unless there is a marble of that color already in the bowl. Then, that marble is removed from the bowl and the new marble does not go into the bowl. (The pair is placed in a separate bin for shipping). Let G, denote the number of marbles currently in the bowl after the nth marble arrives. Compute (a) the expectation E(Gn). (b) lim,+E(Gm).
Paul watches a lot of television sitcoms. When he moves out on his own for the first time, he is really frustrated because all of the apartments he can find to rent seem small and dingy compared to those of even "poor" television characters, even though he has a good job that pays relatively well. He feels like he is not able to be a "real" adult until he gets an apartment that looks like that, and is struggling because his life doesn't seem quite right. This is best understood as an illustration of & Select one: O Altheide's e-audience. O b. Tremblay's cybriety. O c. Herman and Chomsky's manufactured consent. O d. Baudrillard's hyperreality.
