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.
