I think the correct answer would be tympanic membrane. It is a necessary part of the human ear which most known as the eardrum. It is responsible of receiving vibrations from sounds in the surroundings and transmitting these to the auditory ossicles.

At the surface, atmospheric pressure is 1.013 × 10^5 Pa. People can normally snorkel down to a depth of roughly one meter. What
natulia [17]

Answer:

1.01 × 10⁵ Pa  

Explanation:

At the surface, atmospheric pressure is 1.013 × 10⁵ Pa.

We need to find the total pressure on the air in the lungs of a person to a depth of 1 meter.

Pressure at a depth is given by :

P=\rho gh

Where

\rho is the density of air, \rho=1.225\ kg/m^3

So,

P=1.225\times 9.8\times 1\\\\=12\ Pa

Total pressure, P = Atmospheric pressure + 12 Pa

= 1.013 × 10⁵ Pa + 12 Pa

= 1.01 × 10⁵ Pa

Hence, the total pressure is 1.01 × 10⁵ Pa.

What is the relationship between the wavelength of the peak (maximum) of the Gaussian curve and the temperature in degrees Kelvi
Tomtit [17]

Answer:

\lambda_{max}=\frac{b}{T}

Explanation:

Wien's displacement law states that the radiation of the black body curve for different temperatures will give peak values at different wavelengths and this wavelength is related inversely to the temperature.

Formally the law of Wien displacement states that the black body's spectral radiation per unit of wavelength, will give peaks at the wavelength of  \lambda_{max} which is given by the mathematical expression.

\lambda_{max}=\frac{b}{T}

Here, b is proportionality constant  with value of 2.897771955...\times 10^{-3} mK

The wavelength of the peak of the Gaussian curve is inversely related to temperature in degree kelvin.
