  2. Which of the following particles is larger than the rest? a. Alpha particle b. beta particle c. neutron A. Alpha particle, 2 protons and 2 neutrons 1 - $100

  3. 1 - $200 • List the three types of radiation from least penetrating power to most? • beta , alpha, gamma • Alpha , beta, gamma.

  4. 1 - $300 • A helium nucleus with two protons and two neutrons is called a(n) • Alpha particle

  5. 1 - $400 • One type of radioactive device that indicates the intensity of radiation with a clicking sound that increases in frequency as more radiation is present is a(n)_________. • Geiger counter

  6. 1 - $500 • Many people work near a source of nuclear radiation. To detect the amount of exposure they have to radiation, they most likely will use a • Film badge,.., contains regular x-ray film which is mailed in each month to check for exposure.

  7. 2 - $100 • A complete, unbroken path through which electric charges flow is an electric • a. resistance b. circuit c. ohm • B. Circuit, path for the flow of electrons

  8. 2 - $200 • What is the name for materials that transfer flow of electrons easily? • Conductors, usually a metal.

  9. 2 - $300 • If an electrical circuit is described as a closed circuit, does that mean the device is electrified or not? • ON, closed = complete = electric flow

  10. 2 - $400 • What does AC stand for in electrical terms? • Alternating Current

  11. 2 - $500 • When more electric current goes through a wire, what effect does the high current have on the wire? • Gets hotter, more current to be resisted.

  12. 3 - $100 • The type of radioactive particle that can be stopped by a sheet of paper is the • a. beta b. gamma c. alpha • C. alpha; two protons and two neutrons

  13. 3 - $200 • Which radioisotope is commonly used in dating archeological artifacts? • Carbon – 14, compare to atmospheric levels

  14. 3 - $300 • The process by which nuclei having low masses are united to form nuclei with larger masses is nuclear ____________. • Fusion: fuse together

  15. 3 - $400 • Nuclear power plants generate electricity using nuclear __________. • Fission; they break apart U-235 into two smaller.

  16. 3 - $500 • Uranium-238 is used in the process of making atomic energy. What is the difference between uranium- 238 and uranium- 236? • Two neutrons; if protons change, element changes.

  17. 4 - $100 • When an electric current flows, which subatomic part moves through the conductor? • a. proton b. electron c. neutron • B. electron; electricity, negatives move.

  18. 4 - $200 • When an electric current flows, which direction does the energy flow? • From the negative to positive; electricity/electrons

  19. 4 - $300 • The SI (metric) unit of electric current is the • Ampere; amps are the flow of current

  20. 4 - $400 • From the two types of circuits, which is below? • Series, one after the other, single path

  21. 4 - $500 • If you had a circuit with four light bulbs and one 12 volt battery. Which circuit type will have brighter bulbs? • parallel; each bulb is directly connected to the 12 V

  22. 5 - $100 • What is half-life of a radioisotope? • The amount of time needed for HALF of the sample to decay.

  23. 5 - $200 • A sample has a half-life of 3 days. If you start with 60 grams, how much will remain after 6 days? • 15 grams = = =6days/3 days = 2 halve lifes • 60 / 2 / 2 = 15

  24. 5 - $300 • How much of a sample remains after 3 half lives? • 1/8 th the original

  25. 5 - $400 • The formula “V = I x R “ is known as • Ohm’s law

  26. 5 - $500 • What is the current flowing through a circuit with 18 volts and a resistance of 6 ohms? ( V = I x R) • 3 amps; 18v = (?) x 6

  27. Final Jeopardy • List the three things that affect the electrical resistance in a conductor. (Factors that affect the electrical flow) • The wires ; length, thickness, and temperature
