98 ! throughout this lesson, you learned about the lives and contributions of key scientists in this area of physics. create a timeline that ties them all together. the timeline does not need to be highly detailed, but it should do the following: include at least the four major scientists covered in this unit: oersted, ampère, faraday, and tesla. include key contributions of each scientist and provide a year, if possible, for those contributions. note any relationships among these and other scientists, especially if one developed something based on the work of another. arrange the scientists chronologically by their first key contribution, not by their birth date.

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
