Answer: Decreases the transparency of the atmosphere to infrared light.
Explanation: Green House gases are gases such as Carbondioxide,Methane,Water Vapor etc which are present in the Atmosphere,they trap and emit heat in the form of radiations. Green house gases act like a barrier preventing some of the radiations especially of the IR(INFRA-RED) to leave the Earth,which eventually leads to increase in the overall Temperature of the Earth.
The higher the concentration of the Green house gases,the lesser the transparency of the Atmosphere to the Infrared radiation.
Answer:
The sound intensity of source #2 is 38.3 W/m²
Explanation:
Given;
sound intensity of source #1, I₁ = 38.3 W/m²
sound intensity of source #2, I₂ = 2.6 dB greater than 38.3 W/m²
To determine he sound intensity of source #2 in W/m², we must convert 2.6 dB to sound intensity in W/m².
Thus, sound intensity of source #2 = 38.3 W/m² + 1.8197 x 10⁻¹² W/m² = 38.3 W/m²
Therefore, the sound intensity of source #2 is 38.3 W/m²

Answer:
Part a)
Part b)
Part c)
in order to find the average speed we need to know about the the gas molar mass or we need to know which gas it is.
Explanation:
Part a)
As per ideal gas equation we know that
here we know that
n = 3.80 moles
now from above equation we have
Part b)
Average kinetic energy of the gas is given as
here we know that
T = 425.6 K
now we have
Part c)
in order to find the average speed we need to know about the the gas molar mass or we need to know which gas it is.
