Answer:
50 dB.
Explanation:
given,
Amplification needed by the woman,I= 1 x 10⁵ I₀
where as I₀ is the threshold frequency
overall hearing loss of the woman= ?
Using the equation of sound intensity level
The overall hearing loss of woman is equal to 50 dB.
One way to do it is she could right down the data that she got
Silver: bonds with other atoms because of the weak forces of the valence electrons
FALSE - The strong forces of the valence electrons is actually the reason why silver bonds with other atoms.
Water: bonds allow for liquid state at room temperature and prevent conduction
FALSE - Water is a good conductor.
Carbon: bonds with other atoms through strong shared electrical bonds
TRUE - Carbon shares covalent bonds with other atoms.
Niobium: bonds allow for a strong conductivity found in stainless steel
FALSE - Iron and Carbon make up steel.
It all depends on what kind of wave, and what kind of medium.
For mechanical waves, like sound and earthquakes, the speed
is determined by the mechanical properties of the medium, like
density and stiffness.
For electromagnetic waves, like radio and light, the speed is
determined by the electrical properties of the medium, like
magnetic permeability and electrostatic permittivity.
That's a big part of the reason why sound and light travel
at different speeds through air, water, and jello.
