In Chapter 4 (at the end of Section 4.7) I claimed that, for a system with one degree of freedom, positions of stable equilibrium "normally" correspond to minima of the potential energy U (q). Using Lagrangian mechanics, you can now prove this claim. (a) Consider a one-degree system of N particles wi

The measured volumetric flow rate of ethane at 10.0 atm absolute and 35C is 1.00 X 103 Llh. Using an estimated value of the second virial coefficient in the truncated virial equation (Equation 5.3-4), (a) calculate V(Llmol); (b) estimate the compressibility factor, Z; and (c) determine the mass flow

What determines the vertical intercept of the Security Market Line (SML)? What determines its slope? And what will happen to an assets price if it initially plots onto a point above the SML?

Experimental Psychology 7
Design a correlation-based study or a quasi-experiment to test each of the following: a. Hot weather is associated with higher rates of violence in the streets. b. Rap music causes people to become more sexist (rather than the other way around). c. Childhood schizophrenia can be predicted from cognit

Suppose that a polymer of glucose with alternating \(\alpha(1 \rightarrow 4)\) and \(\beta(1 \rightarrow 4)\) glycosidic linkages has just been discovered. Draw a Haworth projection for a repeating tetramer (two repeating dimers) of such a polysaccharide. Would you expect this polymer to have primari
