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.

The first one, valleys. Rivers had to be built over, no one wanted their farms to be turned into a railroad (or at least those with common sense), and deserts had no water and was really hot during the day and cold at night.

Now that you understand the basics about the Berlin Airlift, formulate three questions about this event that you want to know mo
tangare [24]

The correct answer to this open question is the following.

The three questions about the Berlin Airlift are the following.

1.- Why did Soviet leader Joseph Stalin order such an "evil" thing?

2.- What was the reaction of the western European allies to that decision?

3.- How everything ended after almost one year of the blockade?

Here are my answers.

1.- Why did Soviet leader Joseph Stalin order such an "evil" thing?

The Soviet Union needed to have a powerful answer against the allied forces after the recent events. Furthermore, Joseph Stalin wanted to show his power. After Joseph Stalin ordered the blockade of Berlin, people were totally disconnected and could not have any type of contact with the outer world.

2.- What was the reaction of the western European allies to that decision?

The United States and Great Britain would not allow the Soviet Union to spread its influence by cutting Americans off from friendly peoples and territories. That was mainly the goal when they decided to start the Berlin airlift.

That is why on June 26, 1948, Great Britain and the United States started to send help and supplies to Berlin using airplanes. President Harry S. Truman wanted to avoid a direct confrontation with Russia or the possibility of another war in the region, that is why he opted for help by air.

3.- How everything ended after almost one year of the blockade?

In May 1949, the USSR lifted the blockade. It was clear to Stalin that his blockade has failed.
