  • True
  • False

Frage 15

Frage
What do transformers do when transferring electricity from the National Grid to consumers?
Antworten
  • Maintain the voltage of electricity.

Frage 21

Frage
Longitudinal waves show areas of compression and rarefraction?
Antworten
  • True
  • False

Frage 22

Frage
What is the formula for wave speed?
Antworten

Antworten
  • Diffracts only at edges.
  • Little diffraction
  • Maximum diffraction
