As the temperature increases, frequency of sound from each organ pipe will increase as well.
Photon
energy is the energy carried by a single photon with a certain wavelength and
frequency. These terms are related by an equation. <span>
E = hv
<span>where h is the Planck's constant (6.626 x
10-34 J s), v is the frequency which is related to the wavelength by:
λv = c where λ is the wavelength and c is the speed of light (3.00 x
108 m/s)
</span>
Therefore, the energy equation
<span>E = hc / λ
E = (6.626 x 10-34 J s)(3.00 x 10^8 m/s) / 0.0120 m = <span>1.657 x 10^-23 J</span></span></span>
Answer:
a) F₁₂₀ = 1.34 pa A , b) F₂₀ = 0.746 pa A
Explanation:
Part. A
. The definition of pressure is
P = F / A
As the air can approach an ideal gas we can use the ideal gas equation
P V = n R T
Let's write this equation for two temperatures
P₁ V = n R T₁
P₂2 V = n R T₂
P₁ / P₂ = T₁ / T₂
point 1 has a pressure of P₁ = pa and a temperature of (20 + 273) K, point 2 is at (120 + 273) K, we calculate the pressure P₂
P₂ = P₁ T₂ / T₁
P₂ = pa 393/293
P₂ = 1.34 pa
We calculate the strength
P₂ = F₁₂₀ / A
F₁₂₀ = 1.34 pa A
Part B
In this case the data is
Point 1 has a temperature of 393K and an atmospheric pressure (P₁ = pa), point 2 has a temperature of 293K, let's calculate its pressure
P₁ / P₂ = T₁ / T₂
P₂ = P₁ T₂ / T₁
P₂ = pa 293/393
P₂ = 0.746 pa
Let's calculate the force (F20), from this point
F₂₀ / A = 0.746 pa
F₂₀ = 0.746 pa A
It B as i think it fits in the substrate of the atoms
