Problem 5. Reaction wheels. Relevant learning goals: • Analyze problems involving the conservation of angular momentum. Subskills: 1, 5 How do satellites change their orientation? This is a requirement of most satellites and spacecraft. For example, a space telescope needs to point to its targets with high precision. Firing bursts from small rocket engines is far too crude for the task. Most spacecraft contain reaction wheels, also known as momentum wheels. They are flywheels with electric motors to spin up or slow down their rotation. When a wheel spins up in one direction, the spacecraft spins in the opposite direction. The Hubble Space Telescope is a tube 13.2 m long with a mass of 11,100 kg. It has a reaction wheel that is a solid disk of radius of 20 cm and a mass of 45 kg. The telescope turns at a maximum rate of 6º per minute (very slow). (a) How fast do you need to spin the reaction wheel to turn the telescope at its maximum rate? The diameter of the Hubble telescope is about 2.4m, but you can treat it as a thin rod in this problem. (b) How many reaction wheels do you need to turn in any direction?

questions to a small number of people in order to record as much detail as possible. 20. The research method that involves watching the social interaction of people and taking notes, data which is later analyzed for patterns and trends, is known as 21. The ethical obligation to accept research findings that contradict personal beliefs and assumptions, as well as to practice research methods without bias, is known in sociology as 22. A measurement which produces wildly different scores from one day to the next when circumstances have not changed is a measure lacking 23. A measurement which does not capture the theoretical concept that it is intended to capture is a measure lacking 24. Research journals use a system of to ensure that only the best research is published by having other professional researchers on staff to anonymously evaluate and approve incoming papers and studies. 25. When researchers unintentionally affect the behavior of research subjects and thus alter experimental results, this is phenomenon known in sociology as the 26. Written response (answer with a paragraph): Describe an example of a seemingly personal problem and how the sociological imagination creates a broader understanding of it as a social problem? In other words, what are the social influences on this issue 27. Written response (answer with a paragraph): How would the functionalist and conflict perspectives differ in their understanding of the mass media? In other words, how would both perspectives answer the question of what the media does and why?
