    Mirror/Lens Equation and Resistors in Parallel

    I apologize for my pathetic lack of basic math, but could you walk me through the process of how to get the answer?

    36 would be the lowest common denominator. 1/36+1/36+1/36=3/36? 36/3=12 Correct?

    In addition, sometimes I am asked to solve for R2 (using the Parallel circuits equation) and do (using the mirror/lens equation).

    Mirror/Lens Equation and Resistors in Parallel

    I'm not sure how to find the least common denominator when given these formulas:

    Do I have to break these problems up into component vectors?

    #8: A person walks 60.0 m east, then 80.0 m NW. #9: A person walks 15 m west, then walks 7.0 m @ 15 degrees South of West. #10: Two forces act on an object. A 45 N force pushing to the north, and a 70 N force pushing at 20 degrees to the east of north. #11: Some people go for a walk...

    Solving Pressure: P = 7.35N / (.24m x .2m)

    @RoyalCat: How should plug them in?

    Solving Pressure: P = 7.35N / (.24m x .2m)

    1. Relevant equations P=F/A 2. The attempt at a solution P= 7.35 N ------------- (.24m)(.2m) Answer= 150.0 PA. <-- That is the correct answer which my instructor gave me. Although, whenever I plus this into my calculator I wind up with 6.125 or 6.16666... (when...
