Answer: High frequency= High harmonics= Different formants
Explanation:
We are given that sopranos can sing notes at very high frequencies.
Now, when they sing high notes it is difficult to understand their words.
According to the concept of harmonics, it is the integer multiple of the fundamental frequency. And formants are the different frequencies which in turn give us different vocalizations.
Now, the frequency is over 1000 Hz this implies that the harmonics will be greater and in turn formants will be different. So, this is the reason it is difficult to understand the words of sopranos when they are singing at very high frequencies.

Explanation:
The potential energy <em><u>(is the energy by virtue of a particular object's location relative to that of other objects. This term is most of the time linked or associated with restoring forces such as a spring or the force of gravity.) </u></em>seems to be U = mgy 
. In fact, the mgy term has disappeared from the development.

Answer:
(a) = 3.7 × 10⁻⁵
(b) = 4.1 × 10⁻⁶ N.M²/C
Explanation:
(a) Diameter of the sphere, d = 1.2 m
Radius of the sphere, r = 0.6 m
Surface charge density, = 8.1 mC/m2 = 8.1 × 10⁻⁶ C/m²
Total charge on the surface of the sphere,
Q = Charge density × Surface area
= 4πr²σ
= 4 (3.14) (0.12²) (8.1 × 10⁻⁶)
= 3.66 × 10⁻⁵C
≅ 3.7 × 10⁻⁵C
Therefore, the net charge on the sphere is 3.7 × 10⁻⁵C
(b)
Total electric flux (∅)
=Q / ε₀
ε₀ = 8.854 × 10⁻¹² N⁻¹C² m⁻²
Q = 3.66 × 10⁻⁵C
= 3.66 × 10⁻⁵ / 8.854 × 10⁻¹²
= 4.1 × 10⁻⁶ N.M²/C
