Answer
  • Thick curtains
  • Cavity wall insulation
  • Hot water tank jacket

Question 12

Answer
  • 1.5
  • 3
  • 20

Question 14

Question

Answer
  • True
  • False

Question 15

Question
What do transformers do when transferring electricity from the National Grid to consumers?
Answer
  • Maintain the voltage of electricity.
  • Increase the voltage so that current is decreased whilst transferring electricity through pylons and then decrease to lower voltages for consumers.

What two ways provide energy during peak demands of electricity?
Answer
  • Carbon capture fields.
  • pumped storage systems such as that of a hyrdroelectric power
  • Biofuel from vegetable oils.

Answer
  • True
  • False

Question 20

Question

Answer
  • Perpendicular to the direction of energy transfer
  • parallel to the direction of energy transfer

Question 21

Question
Longitudinal waves show areas of compression and rarefraction?
Answer
  • True
  • False

Question 22

Question
What is the formula for wave speed?
Answer
  • Wave speed = frequency x wavelength
  • Wave speed = frequency divided by wavelength

Question 24

Question
When waves diffract,, how big will the diffraction be if the gap is slightly wider than the wavelength?
Answer
  • Diffracts only at edges.
  • Little diffraction
  • Maximum diffraction

Question 25

Question

Answer
  • True
  • False

Question 26

Question

Answer
  • True
  • False
