Unformatted text preview: 4. A simple pendulum is made up of a 2.0 kg mass suspended on a thin aluminum wire. This pendulumhas a period of exactly 4.0 s when operated near the equator at a temperature of 122°F. The pendulum is then moved to an Antarctic weather station where the temperature is — 49°F. The linear coefficient of thermal expansion for aluminum is 24 x 10'6/°C. a. (10, points) What is the length of the pendulum wire at the equator? b.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
