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:
31 m/s
Explanation:
As both the monkey and the darts are subjected to constant gravitational acceleration g = 9.8 m/s2 and both start from rest (vertically speaking). Their vertical position will always be the same. For the dart to hit the monkey, its horizontal position must be the same as the monkey's, which is unchanged before reaching the ground. Therefore, the time it takes for the dart to travel across 70 m must be less than the time it takes for the monkey to drop 25m to the ground. We can find it out using the following equation of motion
For the dart to takes less that 2.26 s to travel 70m, its horizontal speed must at least be 70 / 2.26 = 31 m/s
Answer:
Stars that have lower apparent magnitudes have more brightness.
Explanation:
Greek astronomer Hipparchus devised a system of arranging the luminosity of stars with their apparent magnitude. The brightest stars were in the first magnitude class, and the dimmer stars were in the latter magnitude classes.
Later in the 19th century technology had developed to accurately measure a star's brightness. It was established that a factor of exactly 100 times in intensity was due to difference of 5 magnitudes.

Given :
Pressure, P = 0.4 lb/in².
Depth, h = 42 in.
To Find :
The density of a liquid.
Solution :
Pressure at height h of a liquid of density is given by :
....1)
Here, g = 386.04 in/s²( acceleration due to gravity )
Putting all values in equation 1, we get :
Hence, this is the required solution.
