Question 1
Question
How is sound produced?
Answer
Through the creation of electrical energy which travels though through an elastic medium
Through the displacement of an elastic medium
Through the creation of mechanical energy that breaks down an elastic medium
Through the displacement of a mechanical medium
Question 2
Question
When does a) compression and b) rarefaction occur?
Answer
a) When there is a reduction in pressure at a point in the elastic medium b) When there is an increase in pressure at a point in the elastic medium
a) When there is an increase in pressure at a point in the elastic medium b) When there is a decrease in pressure at a point in the elastic medium
a) When there is no pressure change at a point in the elastic medium b) When there is a decrease in pressure at a point in the elastic menium
a) When there is an increase in pressure at a point in the elastic medium b) When there is no pressure change at a point in the elastic medium
Question 3
Question
How is the sound transmitted across the elastic medium (to the ear)?
Answer
It's propagated along a wave of mechanical energy until it is funneled into the ear by the pinnae
It is propagated along a wave of neural energy until it is funneled into the ear by the pinnae
It is propagated along a wave of neural energy until it makes contact with the pinnae resulting in an action potential
It is propagated along a wave of mechanical energy until it makes contact with the pinnae resulting in an action potential
Question 4
Question

Answer
When there is carbon dioxide present to fuel the energy
When there is an elastic medium present such as in water or in a vacuum
