    Correct Answer
    A. B
    Explanation
    Resistance should be the same for any of them, so use V=IR to find the resistance for each row, A,C,D all get a resistance of 2.4 ohms. B is different

    Correct Answer
    A. A
    Explanation
    When rubbed together one object will GAIN electrons (negative) and the other LOSE electrons (positive) opposite charges, and they would attract

    • A

    • B

    • C

    • D

    Correct Answer
    A. C
    Explanation
    need to increase length AND make it thinner (if make shorter but thinner these have opposite effects as shorter reduces resistance)
