Week 16:  18 December to 22 December 2023

18 December 2023:

In Class:  Variable Resistors and Resistivity:

  • R = 
  •  ρL
     A 
  • R = resistance
    ρ = resistivity
    L = length of conductor
    A = cross-sectional area

    • Expectations:  Students will be able to solve problems using the resistivity equation.

    Lab 12:
    Finish data collection for the Circular Motion Lab.

    Expectations:  Students will be able to use a spreadsheet to solve for mass of the satellite and length of the string.

    Due:  Page 3:136 (73 – 77) and page 3:146 (154).

    Homework:  Pages 3:137-138 (78 – 87).  Finish the Circular Motion lab report.

    19 December 2023:
