what does einstein’s theory of relatively, which posits that movement in space and time is relative to the person measuring them, mean? check all that apply.
1.each person’s perception is one’s own truth.
2.reality is unique to each individual.
3.space and time are constructs that do not exist.
4.each person perceives space and time differently.
5.what people perceive is not necessarily accurate or true.

The theory of special relativity explains how space and time are linked to objects that move at a constant speed in a straight line.

The correct answers are: 1, 2, 4 and 5.

"Einstein concluded that simultaneity is relative; (4) events that are simultaneous for one observer may not be for another." (1) "This led to the counter intuitive idea that time flows differently according to the state of movement, and the conclusion that distance is also relative."

Another strange conclusion of Einstein's work comes from the understanding that time moves in relation to the observer (2, 5).

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.
