Ch. 4 Asymptotic Theory From the discussion of last Chapter it is obvious that determining the dis- tribution of h(X1, X2, . . Xr) is by no means a trival exercise. It turns out that more often than not we cannot determine the distribution exactly. Because of the importance of the problem, however, we are forced to develop approximations the subject of this Chapter

Fluid statics Study of fluid at rest 1 e. not in motion or not flowing On any plane, shear force is zero(no velocity gradient or shear deformation hence only pressure forces exist

I. Choose the Correct Answer 1. The magnitude of the force of gravity between two identical objects is given by Fo. If the mass of each object is doubled but the distance between them is halved, then the new force of between the objects will be

I. Choose the Correct Answer 1. Which of the following quantities are independent of the choice of inertial frame? (There may be more than one correct answer) (A)Velocity (B)Acceleration (C)Force (D)Work Solution: In all the inertial frame, the forces acted on a body are same,=ma=F'=ma', therefore the force and acceleration are independent of the choice of inertial frame

Moral Luck One of the important themes in the freewill debate is the idea that freedom is necessary for moral responsibility. In effect, if hard determinism is the correct view, then we should not hold ourselves or others morally responsible. Libertarians, in particular, seem to hold that in order to be responsible for an act, we must be its \sole author. Here is the principle at issue: Control Principle: You are only responsible for what you have control over. If you steal an axe from my garage and use it to break into a gas station, there's no point in holding me responsible, I didn't

of the humoral branch of the immune system Research on complement began in the 1890s, when Jules bordet at the institut pasteur in paris showed that sheep antiserum to the bacterium vibrio cholerae caused lysis of the bacteria and that heating the antiserum destroyed its bacteriolytic activity. Surprisingly, the ability to lyse the bacteria was restored to the heated serum by adding fresh serum that contained no antibodies directed a The Functions of Complement

Oxidative phosphorylation occurs at cell membrane since there are no mitochondria) Cell wall Cytoplasm Cell membrane The cell wall is outside of cell membrane -rigid, protecting cell from osmotic lysis
