<span>If an object is moving, the amount of kinetic energy it has directly depends upon which of the following factors?</span>
- the object's mass
- the object's velocity
Answer:
Our final answer is option (c) that is :
A resonant mode of your vocal tract.
Explanation:
Lets understand pitch of a sound first:
Pitch: Is the rate of vibrations produced and also the degree of lowness and highness of a tone.
Pitch formant:
When we take air inside our vocal tract it oscillates at different pitches depending upon the cast and capacity of the opening of the vocal tract.
Formant comes from the vocal tract and also at a resonance of our vocal tract.
So basically the vocal tract play a vital role for the formant.
Final answer is : A formant is a resonant mode of our vocal tract.

For this problem, we use the equations derived for rectilinear motion at constant acceleration. The equations are:
a = (v - v₀)/t
x = v₀t + 0.5at²
where
a is acceleration
v and v₀ are the final and initial velocities, respectively
x is the distance
t is the time
First, let's determine the a to be used in the second equation:
a = (7.5 m/s - 0 m/s)/1.7 s = 4.411 m/s²
x = (0)(1.7s) + 0.5(4.411 m/s²)(1.7 s)²
x = 6.375 m
