Frage 1
Frage
How is sound produced?
Antworten
-
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
Frage 2
Frage
When does a) compression and b) rarefaction occur?
Antworten
-
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
Frage 3
Frage
How is the sound transmitted across the elastic medium (to the ear)?
Antworten
-
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
Frage 4
Frage

Antworten
-
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
-
In a vacuum only
-
When there is en elastic medium present
