Answer:
The net magnetic field ta the center of square is
.
Explanation:
Current, I = 12 A , side ,a = 10 cm = 0.1 m
Let the magnetic field due to the one side is B.
The magnetic field is given by
![B = \frac{\mu o}{4\pi}\times \frac{I}{r}\times \left (Sin A +Sin B \right )\\\\B = 10^{-7}\times \frac{12}{0.05}\times \left ( sin 45 + sin 45 \right )\\\\B = 3.4\times 10^{-5} T](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Cmu%20o%7D%7B4%5Cpi%7D%5Ctimes%20%5Cfrac%7BI%7D%7Br%7D%5Ctimes%20%5Cleft%20%28Sin%20A%20%2BSin%20B%20%20%5Cright%20%29%5C%5C%5C%5CB%20%3D%2010%5E%7B-7%7D%5Ctimes%20%5Cfrac%7B12%7D%7B0.05%7D%5Ctimes%20%5Cleft%20%28%20sin%2045%20%2B%20%20sin%2045%20%20%5Cright%20%29%5C%5C%5C%5CB%20%3D%203.4%5Ctimes%2010%5E%7B-5%7D%20T)
Net magnetic field at the center of the square is
B' = 4 B
![B'= 4\times 3.4\times 10^{-5}\\\\B' = 1.36\times10^{-4} T](https://tex.z-dn.net/?f=B%27%3D%204%5Ctimes%203.4%5Ctimes%2010%5E%7B-5%7D%5C%5C%5C%5CB%27%20%3D%201.36%5Ctimes10%5E%7B-4%7D%20T)
Since, the options are not given the question is incomplete the complete question is as follows.:
Which of the following is a major way in which oceans contribute to weather systems?
provide a diverse habitat for many organisms
experience changes in amounts of dissolved salts
store and transport the Sun's heat energy
reach depths that can be as much as 12000 meters
Answer: Store and transport the Sun's heat energy.
Explanation:
Oceanic currents are just like a conveyor belt. It helps in transportation of the warm water and the precipitation from the equator to the poles and the cold water in the poles towards the tropics. This way the oceans counteract the uneven distribution of the radiation of sun that reaches upto the surface earth. This will regulate the global climate.
The term which is considered as being undefined is referred to as a point and is therefore denoted as option A in this context.
<h3>What is a Point?</h3>
This is defined as as small round mark written on a plane which signifies the position or location of a substance. This can also be seen as a dot and is also used to separate a group of numbers such as in the case of decimals etc.
It is referred to as being undefined alongside a plane, line etc as a result of it only being explained using specific examples and descriptions unlike a segment which can be viewed and understood easily when working on the parameter.
This is therefore the reason why a point is undefined and the most appropriate choice.
