What are the problems scientists are trying to solve in order to get to Mars? 5 reasonings

Answers

Answer 1

Answer:

Durante el simulacro, los tripulantes experimentarán las mismas condiciones que si estuvieran viajando a Marte, con agua y comida dosificada, y comunicaciones limitadas.

Pero las condiciones psicólogicas, aunque duras, no son las únicas a las que un astronauta debe enfrentarse en un vuelo tan largo aún nunca realizado.

Los expertos auguran que costará al menos 25 años, que se reducen a 15 en las previsiones más optimistas, antes de que seamos capaces de viajar a Marte.

Which statement describes the power of government provided by the Articles of
Confederation?

Answers

The power of government provided by the Articles of Confederation only consisted of one branch, which was Congress.

The Articles of Confederation was the United States' first constitution. It is known for being very weak and giving little to no power to the federal government. With the Articles, the federal government could not tax the states, regulate trade, draft soldiers, or even create and enforce laws properly. The Articles of Confederation only gave the government one branch, which was Congress. Congress could do numerous things, but it still wasn't enough to build a strong country. Since the government only had one branch, it was very hard to create and enforce laws. In order to pass a law, 9 out of 13 of the states had to agree to it, and in order to amend the Articles, all of the states had to agree. There was no system of courts, so the judiciary branch was essentially up to the states, this meant they could choose to ignore any laws since none would be enforced properly.

Eventually, during the Constitutional Convention of 1787, the Articles of Confederation was meant to be reworked. It ended up getting thrown out all together and the United States Constitution was created instead.

Do you think that the relationship between the settlers and the American Indians effected the success or failure of the settlements?

Answers

Answer:

yes, i do.

Explanation:

the relationship between the settlers and american indians was far from perfect. early settlers arrived with diseases that many american indians died from, and let's not forget the trail of tears when american indians were forced to relocate. there were even times when american indians fought back and attacked settler at their settlements.

if the settlers had been fair and honest with the american indians from the start, the settlements could've been much more successful, attacked less, and the relationship between them and settlers could've been much better.

Answer:

The relationship between the native Americans very much effected the successes and the failures of the colonies. The colonists often didn't have wonderful relationships with the natives because they would cheat them into sighing over land and proposing trades that where in their favor. The natives had better fighting skills and knew the land so when it came time for the natives to fight back the colonies didn't stand a chance.

Answers

Answer:

The Mandate of Heaven.

Explanation:

The Mandate of Heaven was the concept that rulers were bestowed a right to rule by Heaven, and that this mandate granted legitimacy to a dynasty. For one to maintain the Mandate of Heaven, they were to govern by moral societal norms. Those who governed immorally would be considered to have forfeited their mandate; ultimately leading to political upheaval and a new dynasty claiming the mandate.

A famous example of the Mandate of Heaven being used to overthrow a dynasty is the case of 1046 BCE, in which the Zhou people overthrew the wildly immoral Shang dynasty, in turn claiming the mandate and birthing the Zhou dynasty.
