Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.

Does the response "It would start a fire" correctly answer the question "What would happen if all the oil leaked out of a running car engine?"?

Recommendation: Congressional oversight for intelligence-and counterterrorism-is now dysfunctional. Congress should address this problem. We have considered various alternatives: A joint committee on the old model of the Joint Committee on Atomic Energy is one. A single committee in each house of Congress, combining authorizing and appropriating authorities, is another. The new committee or committees should conduct continuing studies of the activities of the intelligence agencies and report problems relating to the development and use of intelligence to all members of the House and Senate. We have already recommended that the total level of funding for intelligence be made public, and that the national intelligence program be appropriated to the National Intelligence Director, not to the secretary of defense. We also recommend that the intelligence committee should have a subcommittee specifically dedicated to oversight, freed from the consuming responsibility of working on the budget. The resolution creating the new intelligence committee structure should grant subpoena authority to the committee or committees. The majority party's representation on this committee should never exceed the minority's representation by more than one. Four of the members appointed to this committee or committees should be a member who also serves on each of the following additional committees: Armed Services, Judiciary, Foreign Affairs, and the Defense Appropriations subcommittee. In this way the other major congressional interests can be brought together in the new committee's work. Members should serve indefinitely on the intelligence committees, without set terms, thereby letting them accumulate expertise. The committees should be smaller-perhaps seven or nine members in each house-so that each member feels a greater sense of responsibility, and accountability, for the quality of the committee's work. The leaders of the Department of Homeland Security now appear before 88 committees and subcommittees of Congress. One expert witness (not a member of the administration) told us that this is perhaps the single largest obstacle impeding the department's successful development. The one attempt to consolidate such committee authority, the House Select Committee on Homeland Security, may be eliminated. The Senate does not have even this. Congress needs to establish for the Department of Homeland Security the kind of clear authority and responsibility that exist to enable the Justice Department to deal with crime and the Defense Department to deal with threats to national security.

Reducing resource use means just what it says using fewer resources. There are lots of ways to reduce our use of resources. Buy durable goods. Choose items that are well made so they will last longer. Youll buy fewer items in the long run, so youll save money as well as resources. Thats a win-win! Repair rather than replace. Fix your bike rather than buying a new one. Sew on a button instead of buying a new shirt. Youll use fewer resources and save money. Buy only what you need. Dont buy a gallon of milk if you can only drink half of it before it spoils. Instead, buy a half gallon and drink all of it. You wont be wasting resources (or money!) Buy local. For example, buy local produce at a farmers market, like the one in Figure 2.20. A lot of resources are saved by not shipping goods long distances. Products bought at farmers markets use less packaging, too! About a third of what we throw out is packaging.

Question: "What are two examples of repair rather than replacing?"

Response: "Buy smaller quantity of milk, buy local"

Problem: Some of the most unusual effects of Hellenization can be seen in Afghanistan and India, in the region of the relatively late-arising Greco-Bactrian Kingdom (250 BC-125 BC) in modern Afghanistan, Pakistan, and Tajikistan and the Greco-Indian Kingdom (180 BC - 10 CE) in modern Afghanistan and India. There on the newly formed Silk Road Greek culture apparently hybridized with Indian, and especially Buddhist culture. The resulting syncretism known as Greco-Buddhism heavily influenced the development of Buddhism and created a culture of Greco-Buddhist art. These Greco-Buddhist kingdoms sent some of the first Buddhist missionaries to China, Sri Lanka, and the Mediterranean (Greco-Buddhist monasticism). The first figural portrayals of the Buddha, previously avoided by Buddhists, appeared at this time; they were modeled on Greek statues of Apollo. Several Buddhist traditions may have been influenced by the ancient Greek religion: the concept of Boddhisatvas is reminiscent of Greek divine heroes, and some Mahayana ceremonial practices (burning incense, gifts of flowers, and food placed on altars) are similar to those practiced by the ancient Greeks. One Greek king, Menander I, probably became Buddhist, and was immortalized in Buddhist literature as 'Milinda'. The process of Hellenization extended to the sciences, where ideas from Greek astronomy filtered eastward and had profoundly influenced Indian astronomy by the early centuries AD. For example, Greek astronomical instruments dating to the 3rd century BC were found in the Greco-Bactrian city of Ai Khanoum in modern-day Afghanistan while the Greek concept of a spherical earth surrounded by the spheres of planets was adopted in India and eventually supplanted the long-standing Indian cosmological belief of a flat and circular earth. The Yavanajataka and Paulisa Siddhanta texts in particular show Greek influence.

Question: "Greco-Buddhism was the result of the meshing between Greek culture and culture of which country?"

Answer: "Bangladesh"

What if two children push a swing at the same time? Would the swing go higher? Yes, together their force would be more. It is common for forces to be combined. Most objects on Earth have at least two forces acting on them. Do you know what one of them is? Of course, that force is gravity. How many forces do you have on you right now? Gravity pulls you down toward the center of Earth. Your legs exert a downward force. They hold you up against the pull of gravity. Consider the example in Figure 1.3. A book is resting on a table. Gravity pulls the book downward. It has a force of 20 newtons. At the same time, the table pushes the book upward. Its force is also 20 newtons. The table opposes the pull of gravity.

Question: "If two children push a swing at the same time, will the swing go higher?"
