6. What is the formula for specific heat capacity?

  • Energy = mass / specific heat capacity / weight
  • Change in temperature = mass / specific heat capacity x energy
  • Energy = mass x specific heat capacity x change in temperature
  • Specific heat capacity = energy x mass x change in temperature

7. What is red-shift?

  • The shifting of light to the red side of the spectrum due to speed.
  • The shifting of light to the red side of the spectrum due to a decrease in wavelength.
  • The shifting of light to the red side of the spectrum due to an increase in wavelength.
  • The shifting of light to the red side of the spectrum due to distance.

8. What is conduction?

  • When metals are used in a circuit.
  • The transfer of thermal energy through particles coming into contact with one another.
  • Particles changing from one state to another.
  • The transfer of energy through cool particles being replaced by hot particles.

9. Which of the following is incorrect about sound waves?

  • They're made of compressions and rarefactions.
  • They're perpendicular to the direction of travel and energy transfer.
  • They're longitudinal.
  • They're parallel to the direction of travel and energy transfer.

10. Name the main advantage of nuclear power.

  • It is the biggest supplier of electricity in the UK.
  • It does not produce greenhouse gases.
  • It is a renewable energy resource.
  • It is a very safe process to produce electricity this way.

11. What does the amplitude of a sound wave affect?

  • The direction of travel.
  • The pitch.
  • The volume.
  • The length.

12. Which of the following is true about refraction?

  • The angle of incidence is equal to the angle of refraction.
  • The angle of refraction is greater than 90 degrees.
  • The angle of incidence is greater than the angle of refraction.
  • The angle of incidence is less than the angle of refraction.

13. Radiation is transferred via what?

  • Rays.
  • Particles.
  • Waves.
  • Beams.

14. How are nuclear power stations powered?

  • Uranium is reacted with aluminium to produce steam which turns the turbine.
  • Uranium rods are kept in water, when removed from the water they produce steam which turns a turbine.
  • Uranium rods are dipped into water which creates steam to turn the turbine.
  • Uranium is burnt to produce steam which turns a turbine.

15. When are waves diffracted the most?

  • When the size of the slit is equal to the wavelength.
  • When the size of the slit is smaller than the frequency.
  • When the size of the slit is greater than the wavelength.
  • When the size of the slit is equal to the frequency.

16. Which of the following is untrue about images formed by plane mirrors?

  • The image is virtual.
  • The image is in front of the mirror.
  • The image is behind the mirror.
  • The image is laterally inverted.

17. When a vehicle travels towards you, what is happening?

  • The pitch is increasing: the wavelength decreases, frequency increases.
  • The pitch is decreasing: the wavelength increases, the frequency decreases.
  • The pitch is increasing: the frequency decreases, the wavelength increases.
  • The pitch is decreasing: the wavelength decreases, the frequency increases.

18. Which electromagnetic wave has the smallest wavelength?

  • Infra-red waves.
  • Visible light.
  • Gamma rays.
  • Radio waves.

19. Which of the following does not describe a loud, high pitched noise?

  • High frequency.
  • Low frequency.
  • Big amplitude.
  • Small wavelength.
