Your lungs aren’t the ones that make the sound
<h3><u>Answer;</u></h3>
electric potential
<h3><u>Explanation;</u></h3>
Electric potential is the electric potential energy per unit charge.
Mathematically; V =PE/q
Where; PE is the electric potential energy, V is the electric potential and q is the charge.
Electric potential is more commonly known as voltage. If you know the potential at a point, and you then place a charge at that point, the potential energy associated with that charge in that potential is simply the charge multiplied by the potential.
Evidence: Data gathered
Experiment: Looking through a telescope
Observations: Testing what happens
Reasoning: Thinking a problem through
I believe that these should be correct.
Hoping you pass!
The answer is D. As the ambulance gets closer, the sound waves are compressed relative to the person; so the frequency increases.
