Answer:
optical
Explanation:
Polarization fall under optical property of material.
Polarization is a property of certain electromagnetic waves in which the direction and the magnitude of electric field are related in some way. Plane polarized light consist of waves in which direction of vibration of waves is same for all waves. Light may be polarized by reflection or by passing it through filters.
Answer:
24 degrees Fahrenheit.
Explanation:
The moist adiabatic rate is related to the variation of the temperature as the altitude increases.
A typical value is around 9ºF/km. This means that for each km, the temperature decreases 9ºF.
In this problem, we have that:
The temperature at the ground level is 60 degrees Fahrenheit.
So 4km above sea level it is going to be 60 - 4*9 = 24 degrees Fahrenheit.
The conflict between Russia and Chechnya began 20 years ago when Chechnya located in Russia's North Caucasus region that had announced its independence. This attempt of separation from the union has started the war killing many nationals. As of writing, Chechnya is a de facto independent state while being formally part of Russia.
