A thin-walled hollow cylinder with mass m1 and radius R1 rolls without slipping on the inner wall of a larger thin-walled hollow cylinder with mass m2 and radius R2 >> R1. Both cylinders' axes are aligned and horizontal, and some magical mechanism ensures this perfect friction contact between them. Unfortunately for you, the larger cylinder rolls without slipping on a horizontal surface. Describe the motion including small oscillation frequencies near any equilibria if the systems is released from rest with the inner cylinder at some angle α0.

Suppose you perform the following multiple regression: Y = B0 + B1X1 + B2X2 + B3X3. You find that X1 and X3 have a near perfect correlation. How would you conclude on the utility of your regression result? This is a problem of multicollinearity which renders the entire regression invalid. This is a problem of multicollinearity which nevertheless does not invalidate the utility of the model as a whole This is NOT a regression problem and inferences made using the model and the respective coefficients remain valid. This is a problem of multicollinearity. However inferences made concerning the individual contribution of the model coefficients remain valid

We are looking at the market for gasoline in the United States, this week. Begin with the market in equilibrium. A report is released that we should expect the price of gasoline to rise in the near future, with up to a 50-cent increase sometime next week. Assume that we all have access to this information. Graph the changes and answer the following questions:
How do the unhappy participants react?

1. Investigate contemporary institutional slavery or human trafficking around the globe, using a specific example. What societal dynamics do these situations have in common with slavery in the United States?
2. Do you believe that slavery is fundamentally wrong? Explain yes or no. Many commodities would be considerably more expensive without the people who work for near to nothing around the world. Would you be willing to pay higher prices if it meant an end to such poor wages and conditions for labor? What about how this affects prices around the world, such as in developing countries?

What practical application can we expect from particle physics a century or two from now? What use can we make of quark-gluon plasmas or strange quarks? How can we harness W- and Z-bosons or the Higgs boson? Nuclear physics has given us nuclear plants and the promise of fusion power in the near future. What about particle physics? If we extend our timeframe, what promise does string theory give us? Can we make use of black holes?

A soccer player kicks a lock horizontally of a 46 m high cliff into a pool of water. If the player hears the sound of the splash 3.26 s later, (a)what was the initial speed given to the rock in m/s?assume a speed of sound in air is 343 m/s. (b)What if the temperature near the cliff suddenly falls to 0゚ C reducing the speed of sound of 331 m/s, what would the initial speed of the rock have to be in m/s for the soccer player to hear the sound of the splash 3.26 s after kicking the rock?
