Questions and Answers

What is the relationship between elasticity and inertia in the vibration of a stringed guitar?

  • They both result in increased pressure
  • Inertia is directly proportional to elasticity
  • Elasticity leads to compression while inertia leads to rarefaction
  • They are opposite to each other (correct)

    • What causes a one stringed guitar to vibrate when it is moved from position 2 back to its rest position?

  • The restoring force due to its elasticity (correct)
  • The compression of air molecules around it
  • The increasing inertia from its movement
  • The increase in pressure caused by nearby molecules

    • Why does a one stringed guitar move through its equilibrium point after reaching its rest position?

  • In response to the high compression of air molecules
  • Because of the low elasticity of the string
  • Due to the high inertia of the string (correct)
  • Caused by an increase in air pressure
