Answer: Different vocal tract and harmonics
Explanation:
We are given that a small boy and a grown woman both speak at approximately the same pitch.
To distinguish between the two, we check their harmonics which is different for both of them owing to the different vocal tracts they have. Owing to different vocal tracts, they each produce different harmonic which is actually the multiple of frequency of the wave. Thus, we can make the determination using this.
The answer is ionic bonds
Answer:2 s
Explanation:
Given
initial velocity 
distance travel 
time taken to travel 70 feet


using
to get roots

t=2 and -2.19
only feasible time is 2 s
thus it requires 2 s to cover 70 feet
Explanation:
When treating the electron as a wave, the concept of electrons orbiting the nucleus allows for the distinct energy levels.The diameter of electron orbits matches the orbit radii which also discrete the energy levels.
The small number of deflected particles were repelled from powerful heavy positively charged central cores which is known as the atomic nucleus.
