Answers:</h2>
-The first direct detection of gravitational waves came in 2015
-The existence of gravitational waves is predicted by Einstein's general theory of relativity
-Gravitational waves carry energy away from their sources of emission
<h2>
Explanation:</h2>
Gravitational waves were discovered (theoretically) by Albert Einstein in 1916 and "observed" for the first time in direct form in 2015 (although the results were published in 2016).
These gravitational waves are fluctuations or disturbances of space-time produced by a massive accelerated body, modifying the distances and the dimensions of objects in an imperceptible way.
In this context, an excellent example is the system of two neutron stars that orbit high speeds, producing a deformation that propagates like a wave,<u> in the same way as when a stone is thrown into the water</u>. So, in this sense, gravitational waves carry energy away from their sources
.
Therefore, the correct options are D, E and F.

Answer:
The gravitational pull from the Moon has the greatest effect on the size of the tides.

Elaborate rehearsal involves organizing and breaking down information into easier groups to expand capacity. Rehearsal is the verbal repetition of information. These techniques are especially important for the improvement of long-term memory.
Six strategies of elaborate rehearsal are:
1. Rephrase information into your own words.
2. Create your own study questions and answer them.
3. Use images to help you.
4. Group terms that are of the same topic together.
5. Use a mnemonic strategy.
6. Space our your learning and don't try to cram in on sitting.
