The answer that is most suitable is earth's hydrologic cycle.
Water does not remain locked up in the oceans, icecaps, groundwater systems , or the atmosphere. Instead water is continually moving from one reservoir to another. This movement of water is called the hydrologic cycle.
Although water in the hydrologic cycle is constantly in motion, it never leaves the earth. The earth is nearly a "closed system" like a terrarium. This means the earth neither gains nor loses much matter, including water.

Answer:
The intensity of the emerging light reduced to 25%
Explanation:
Given :
Unpolarized light intensity = 
Initial polarizer angle = 0°
Final polarizer angle between optic axis and transmission axis = 45°
Unpolarized light passes through first polarizer the intensity reduces to half.
after second polarizer the intensity is half till the last polarizer,


Therefore, the intensity of the emerging light reduced to 25%
Answer:
56 kg m/s
Explanation:
Δp = mΔv
Δp = (7.0 kg) (8.0 m/s − 0 m/s)
Δp = 56 kg m/s
Answer and Explanation:
A potential divider, as the name itself gives a clear description of a simplified circuit which divides the potential across different circuit elements.
The potential divider circuit divides the potential depending upon the respective value of the elements of the circuit,
Given circuit diagram shows a potential divider circuit.
The working of this circuit is as :

where
V = Input voltage
V' = output voltage
