5 0

Answer:

- the first direct detection of gravitational waves came in 2015

- gravitational waves are predicted to travel through space at the speed of light

-  the existence of gravitational waves is predicted by Einstein's general theory of relativity

Explanation:

The gravitational waves are waves that are produced by the objects, and depending on the mass of the object they can be stronger or weaker in their influence.

These waves have been in the minds of the scientists for more than a century now, with Einstein predicting them in his theory of relativity. The only problem with these waves was that there was no proof of them. The proof finally came in 2015 when these waves were detected from the first time, with two black holes to be thanked for that as they were the source of them.

These waves are predicted to be able to travel with the speed of light through space when they have small amplitudes.

According to Hebrew traditions, it was around 1250 BCE that Moses led them out of A. Egypt B. Canaan C. Palestine D. Mesopotamia
Oliga [24]

Answer:

A. Egypt

Explanation:

The Hebrew traditions say that a men named Moses was the one that led the Hebrews out of Egypt and into the Promised Land, somewhere around 1250 BCE. According to the legend, Moses was a men that communicated with God, so he was well respected among the Hebrews. Because the Hebrews were enslaved by the Egyptians and treated very badly, they wanted to escape into freedom, but were afraid to do so. Moses was not afraid though, and he openly stood up to the pharaoh and led the Hebrews out of Egypt successfully, eventually reaching the Promised Land.

The existence of Moses as a historical figure is disputed by the historians though, as there are no evidence of any sort that he actually existed, so he is thought to be a mythological figure. On the other hand, it is thought that there is a possibility that a men with this name existed in the 13th century BCE, and that he was well respected and had some leading role among the Hebrews, so latter numerous things, often exaggerated, were attributed to him.
