The math suggests that for every parsec the rate of moving away is 71 km/s, so when two galaxies are separated by two parsecs we come to 142 km/s speed of moving away from each other. If we take the first light ever (from what is known so far) the cosmic microwave radiation, is 46 billion light-years away from us at all directions, which comes at 4,200 megaparsecs, which comes at 13.7 billion light-years, so it will come to 29,820,000 km/s. It all depends from the distance between the galaxies which is calculated by their type of colour and movement in comparison to other galaxies.

According to the Tenth Amendment, the powers of________ are limited to only
Travka [436]

Answer:

the federal government

Explanation:

The Tenth Amendment to the United States Constitution restricts the federal government's powers to those specified in the Constitution and its amendments, leaving all other powers to the states and "the general population." This is significant in light of the fact that the federal government has only recently defined forces, which are limited to those "recorded" in the Constitution, otherwise known as identified forces. Without that constraining modifier, the federal government, specifically Congress, has been held to have unenumerated powers under what is known as the "necessary and proper" provision (Article I, Section 8), which allows Congress to make any laws that are necessary and proper to carry out the listed obligations, those that are specifically named. The manner in which the crucial and valid provision was integrated has been deciphered to imply that it encompasses many powers.
