The drawing shows four situations in which a positively charged particle is moving with a velocity v through a magnetic field b. in each case, the magnetic field is directed out of the screen toward you, and the velocity is directed to the right. in only one of these drawings is the magnetic force f physically reasonable. which one is it?

Option 1.

Explanation:

The correct diagram can be determined by using the right hand rule. This can be used to estimate the of two vector forces. Therefore, the direction of the velocity v is to the right while that of the magnetic field B is out the plane. Since the in figure, we have a positively charged particle, the position of the magnetic force F is shown in option 1.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
