      Protons

    • C. 

      Electrons

    • D. 

      All of the above because they all make up the atoms

  • 2. 
    In the static electricity lab, which of the following was true?
    • A. 

      The friction between your hair and the balloon caused your hair to lose electrons and the negatively charged balloon was then attracted to your positively charged hair.

    • B. 

      The friction between your hair and the balloon caused your hair to gain electrons and the negatively charged balloon was then attracted to your positively charged hair.

    • C. 

      The friction between your hair and the balloon caused your hair to lose electrons and the positively charged balloon was then attracted to your positively charged hair.

    • D. 

      The friction between your hair and the balloon caused your hair to lose electrons and the negatively charged balloon was then attracted to your negatively charged hair.

  • 3.

      2 g/mL

    • B. 

      0.5 g/mL

    • C. 

      0.5 g*mL

    • D. 

      2 g*mL

  • 4. 
    True/False:  A Leyden jar could kill you.

      True

    • B. 

      False

  • 5. 
    The roses smelled lovely is an example of:
    • A. 

      Qualitative data

    • B. 

      Quantitative data

  • 6. 
    Lightning forms when:
    • A. 

      The bottoms of clouds become positively charged and attract electrons from the surface of the earth.

    • B. 

      Storms cause electrons to be ionized from air molecules and when they all happen in a straight line . . . uh oh!

    • C. 

      Zeus causes it to happen.

    • D. 

      There is a potential difference between the top and bottom of a cloud which causes streamers to form near the earth and lightning happens when the electrons are able to flow from the cloud to the earth.

  • 7. 
    The resistance flowing through a 120 Volt circuit with 10 Amps of current would be:
    • A. 

      1200 Ohms

    • B. 

      12 Ohms

    • C. 

      1200 Watts

    • D. 

      12 Watts

  • 8. 
    Electrical power is calculated by multiplying the:
    • A. 

      Current X Resistance

    • B. 

      Current X Voltage

    • C. 

      Voltage X Resistance

  • 9. 
    The reason you could use a pickle light for a light bulb is because:
    • A. 

      The arcing between the nails makes protons glow orange when electricity runs through the pickle.

    • B. 

      You can use any sort of fruit or vegetable as a light bulb, they will all glow orange.

    • C. 

      Electrons in the sodium in the pickle get excited and jump to higher energy levels releasing photons of light when they fall back down.
