Answer: A. Thermohaline circulation
Explanation:
The thermohaline circulation is a phenomena which involves the movement of the oceanic currents because of the differences that occur in the temperature and salinity of oceanic water. These two factors changes the salinity and density of the water and fluctuating the climatic conditions. Cold water is particularly denser than the warm water. The water with more salinity is also denser over water with less salinity. The deep oceanic water currents brings changes in the density as well as the salinity of water hence, the circulation of water is called as thermohaline circulation. Some part of warm water will evaporate from the surface layer of the ocean this will lead to the flow of warm wind currents and water to the regions of cold regions of the seawater.
On the basis of the above description, A. Thermohaline circulation is the correct option.
Yes it is true that electrical fences displays a warning about voltage and amperage of the fence. It has to be first understood that power is directly proportional to voltage as well as current. So higher the voltage or higher the current flowing through the fenses, higher will be the power. So any person touching the fence should always be aware of the voltage and current flowing through the fence, otherwise it can be very deadly. Sometimes it can be seen that a high voltage is being passed through the fence and the current passed is comparitively low. This will not decrease the total power flowing through the fence.

The answer is true. fluorescence demonstrates a sparkly like light beam and also can bounce off of other beams
Answer:
174.85 W
Explanation:
Area of plate = 3.14 x (15x 10⁻²)²
= 706.5 x 10⁻⁴ m²
heat being radiated by convection = 12 x 706.5 x 10⁻⁴ ( 180 - 15 )
= 139.88 W. This energy needs to be fed by heat source to maintain a constant temperature of 180 degree.
If power of electric source is P
P x .8 = 139.88
P = 139.88 / .8
= 174.85 W
