Answer:
b. There is no definite top to the atmosphere. The pressure and density gradually get smaller as the altitude gets larger.
Explanation:
There is no specific top of the atmosphere. It varies from place to place. But generally it is considered to be 480 kilometers thick. But majority of its thickness is limited to 16 km only above earth surface. The pressure and density gradually get smaller as the altitude gets larger. The air pressure at sea level is 14.7 pounds per square inch and it decreases to 10 pounds per square inch at a height of 3 kilometers. From the above discussion we say that option B is correct
Answer:
The wavelength is 
Explanation:
From the question we are told that
The thickness is 
The refractive index of the non-reflective coating is 
The refractive index of glass is 
Generally the condition for destructive interference is mathematically represented as
Where 
is the angle of refraction which is 0° when the light is strongly transmitted
and n is the order maximum interference
so
at the point n = 1
at n =2
Now we know that the wavelength range of visible light is between
So the wavelength of visible light that is been transmitted is
The answer is D- it has a high resistance and is a conductor
hope this helps !

The pressure between two costs is proportional to the product of the charges.
If solely one of the expenses is decreased by way of a element of 3, then the pressure is decreased with the aid of a thing of 3.
If each prices are reduced by a thing of 3, then the pressure is reduced via a issue of 9.
