EDEXCEL PHYSICS ADDITIONAL P2 QUIZ VARIOUS TOPICS

Please don't use this quiz as a staple revision source. I have made flash cards for P2 (not electronically) and when filtering through which answers I know and which I don't, this quiz is based on all the flash cards I didn't know.

1. How do coolants control chain reactions?

  • Removing the thermal energy produced in fission reactions so it can be used to heat water to produce steam to power turbines
  • By slowing down fast moving electrons
  • By using kinetic energy
  • Changing thermal energy into electrical energy to power turbines

2. What happens in radiotherapy?

  • A beta source is used to target cancerous cells by rotating an intense beam of gamma rays, most cancer cells can be killed with little damage to healthy cells.
  • A gamma source of cobalt is used to target cancerous cells by rotating an intense beam of gamma rays, most cancer cells can be killed with little damage to healthy cells.
  • A gamma source of iodine is used to target cancerous cells by rotating an intense beam of gamma rays, most cancer cells can be killed with little damage to healthy cells.
  • An alpha source of cobalt is used to target cancerous cells by rotating an intense beam of gamma rays, most cancer cells can be killed with little damage to healthy cells.

3. Disadvantages of nuclear power?

  • High risk of nuclear accidents
  • Expensive and renewable
  • Expensive, bad reputation with the public, waste is radioactive for years
  • Lots of background radiation produced, waste is hard to deal with

4. What is terminal velocity?

  • A constant velocity - when resultant force is 100
  • An alternating velocity
  • A constant velocity - when air resistance is equal to the weight of the object and the resultant force is now 0
  • A slow velocity

5. How does the KE produced from fission, in nuclear power stations, power turbines?

  • When KE is turned into heat and used to boil water to make steam - the steam powers turbines
  • The KE faces air resistance
  • When KE just powers turbines
  • The KE is changed to electrical energy which powers the turbines
