Answer:

A force exists that we knew nothing about that causes the acceleration.

Explanation:

In 1998, scientists observed from distances of supernovae in remote galaxies that the enlargement of the universe is accelerating. Besides, there is evidence that suggests that the universe is  flat and infinite, as well as accelerating in its expansion.

ioda

Answer:

a. To calculate the report, the only observation that is valid and accurate, are observation 1, 3, 6, 8,9. Because in this observation, the two observed answers are the same for the student, therefore our calculation, to be accurate, we should only use this observations that are the same to calculate .

Observation 1,6,9 which was YES for the two observers

Observation 3 and 8 which was No for the two observers.

This means that from the observation we can term valid, the number of YES is greater than the number of NO.

That means the child is aggressive. Though the research has so much error in the reliability of the observation.

b. The observation does not demonstrate inter observers reliability, because their records in an observation are not the same, that means a specific method to record the childs answer of YES or NO was not defined, and this made the research to have more, error.

We can't tell the result in observation 2,4,5,7,10 because those observation contradict each other, and this has limited the acceptance of the result of this observational research,

How can you relate the nature of anthropology sociology and political science to your daily life​
melomori [17]

Explanation:

Part of what most of the people today do every day in their daily life​ includes learning things they did not know before.

For example, by the definition of anthropology, it focuses on studying the culture of a particular society in the past or present. While sociology generally involves studying the behavior of a particular group. Political science, on the other hand, studies the governments, especially how they use their powers.

<em>By combining the knowledge of these fields of study, it will be possible to understand why and how a particular culture differs from ours</em>, such as the Native American culture.
