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