Hanging from the ceiling over a baby bed, well out of baby’s reach, is a string with plastic shapes, as shown here. The string is taut (there is no slack), as shown by the straight segments. Each plastic shape has the same mass _m_ , and they are equally spaced by a distance _d_ , as shown. The angles labeled \theta describe the angle formed by the end of the string and the ceiling at each end. The center length of sting is horizontal. The remaining two segments each form an angle with the horizontal, labeled \phi . Let T_{1} be the tension in the leftmost section of the string, T_{2} be the tension in the section adjacent to it, and T_{3} be the tension in the horizontal segment.

There was a growing concern at the Environmental and Agriculture Department about the rising levels of COâ in the atmosphere. It was clear that human activities, especially the burning of fossil fuels, were the primary cause of this increase. The department assigned a team of data scientists to research the potential consequences of climate patterns in the United States. They studied the trends of COâ emissions over the years and noticed a significant uptick in recent times. The team simulated various scenarios using climate models and predicted that if the current trend continues, there will be disastrous consequences for the climate. The four graphs displayed inFigure 8.11depict the identical dataset from four different researchers.

Box A has a horizontal force of three times that of box B. (a) Which box is traveling faster at this distance away from the starting point? Briefly explain your reasoning. (b) Based on experimental data, an equation that fits the data is suggested for the final speed, _V_ , which may not be correct: V = KF , where _K_ is a constant with appropriate units and _F_ is the horizontal applied force. Is this equation consistent with your answer from part a? Explain why or why not. Does this equation make sense? Explain why or why not.

The rules of politics are not always the same as the rules of economics. In discussions of setting budgets for government agencies, there is a strategy called âclosing the Washington Monument.â When an agency faces the unwelcome prospect of a budget cut, it may decide to close a high-visibility attraction enjoyed by many people (like the Washington Monument). Explain in terms of diminishing marginal utility why the Washington Monument strategy is so misleading.Hint: If you are really trying to make the best of a budget cut, should you cut the items in your budget with the highest marginal utility or the lowest marginal utility? Does the Washington Monument strategy cut the items with the highest marginal utility or the lowest marginal utility?
